Tsumugi's🔨WishMallet Help

This app turns one photo and a short description into a video with a voice, entirely inside your own PC. This page explains the screens and how to create a video step by step, so you can follow it even if this is your first time.

🚀 Your first video in 3 steps

Once setup is finished, try making one video with a sample photo. The tour that appears the first time you start the app guides you through the same steps on the screen.

① Add one photo“+ Add” on the “Create” tab → the sample 01_tsumugi.jpg
② Answer 3 questionsAnswer in “🧭 Guided writing”, then press “✨ Format prompt”
③ Create the video“Create the video” → when it is ready, “▶ Play”

In ② you only answer three things: “Age, gender and occupation?” in ① (for example 13, female, Japanese), “Features” in ① (for example junior-high student) and “What are they saying?” in ② (for example Hi, nice to meet you!). Detail, quality and the other settings can stay as they are (the length starts at 1 second, which finishes fastest).

The detailed steps are in 3. How to create a video, and where everything is on the screen is in 2. The screens.

1What this app can do

How it works: a photo, a voice (optional) and a description go in, and a video with a voice is made inside your PC 🖼 Photo 🗣 Voice (optional) 📝 Description 💻 Made insideyour PC 🎬 Videowith a voice
Your photos, voices and descriptions are never sent over the internet

To run the app you need Windows 11, an NVIDIA graphics card (12 GB or more of video memory), 64 GB or more of memory and 105 GB or more of free disk space. It does not run on AMD (Radeon) or Intel graphics cards. You can check before you buy with the System check (Web quick version).

🎁 Before you buy, you can use the 7-day free trial (up to 3 videos a day). See 8. The Settings screen, “Free trial”.

2The screens

The diagram below is a simplified view of the screen when the “Create” tab is open. The red circles match the explanations under the diagram.

Use the tabs along the top to switch screens.

TabWhat the screen is for
CreateAdd a photo and a description, and create a video. The progress while it is being made and the finished video also appear here.
HistoryA list of the videos you have made so far. You can watch them, re-create them, cut out favorite moments and more.
Best shotsA photo album of your “favorite single frames” cut out of your videos.
SettingsLanguage (Japanese / English), save location, license, diagnostics for when something goes wrong, and more.

While the “Create” tab is open, the following buttons appear at the right end of the tabs (💾 Save to history is at the bottom of the “Create” screen, next to Create the video).

ButtonWhat it does
🧹 Clear all inputsClears the reference pictures, voices, reference videos and the description, and puts detail, length, shape and quality back to their first values (you will be asked to confirm; the photo and video files on your PC are not deleted). What you typed in Guided writing is not cleared (the button with the same name inside the guide clears it).

Hover the mouse over a button or an input box to see a short explanation. When in doubt, hover first.

3How to create a video

Open the “Create” tab and work from top to bottom.

The first time you start the app, a short walkthrough (the tour) appears over the screen. Just keep pressing “Next” and you follow the same flow as this chapter. If you do not need it, you can close it right away with the “×” at the top right, “End tour”, the Esc key or a click on the dark background (it will not appear again). To see it again, go to “Settings” → “About” → Take the tour.

① Add a photo (reference picture)

You can also drag and drop files onto the ① area. What happens depends on what you add:

What you add to ①What happens
🖼 Photo or illustration
PNG / JPEG / WebP
It goes into a new slot (up to 9).
🔊 Voice or sound
WAV / MP3 / M4A / FLAC / OGG
Added with + Add a sound in a photo's slot, it becomes that person's voice. Dropped straight onto ①, it becomes a “Sound only (no picture)” slot; you can add a photo later with + Add a picture.
🎞 Video
MP4 / MOV / MKV / WebM
The “Choose a picture and a sound” screen opens. Pick one moment of the video to use as the photo and a part to use as the voice (up to 5 seconds), then press Add; both go into one slot together (untick “Add the sound too” if you do not need the sound).

② Describe the video you want

Write the video you want to see in the description box. A single line is enough (for example A fantasy story). There are three ways to write it.

🧭 Guided writingThe easiest. Just answer questions and the description is written for you. Start here if you are new.
✨ Auto promptWrite a few words and press it. It is rewritten into English wording that suits video generation.
✍ Write it yourselfPut the words you want spoken in double quotes (for example "Welcome!"). They are spoken in the language you wrote them in.

🧭 How to use Guided writing

Press 🧭 Guided writing at the top right of the box and a screen with the following three columns opens. Answering only what you know is fine (anything can stay empty).

👤 ① CharactersFor each photo: age, gender, occupation, features and outfit. The age can be just a number. Tick “Non-human” for a dog, a cat and so on, and “Anime” for an anime drawing.
🎬 ② Scenes (scenario)Where they are and what is happening, who says what, and subtitles. Use “+ Add a scene” to add scenes in the order things happen.
📝 ③ The descriptionThe text built from ① and ② appears right away. The box above it is for the background music of the whole video.

✨ How to use Auto prompt

How to show subtitles (Guided writing)What to do
Use the spoken words as the subtitleType the words in “What are they saying?” and tick “Show subtitles” (leave the subtitle box empty).
Show a subtitle that differs from the spoken words
(a translation, narration and so on)
Type the words in “What are they saying?”, type the text you want to show in the subtitle box to the right of “Show subtitles”, and tick “Show subtitles”.
No voice, only a subtitleLeave “What are they saying?” empty, type the text in the subtitle box and tick “Show subtitles”.
No subtitlesDo not tick “Show subtitles”.
Tip for getting what you want: results are steadier when you describe the place, the time of day, the person's movement and the spoken line one by one, in concrete terms. The quickest way is to start from the text made by “Guided writing” and adjust it little by little.

Transform the person in one photo (Guided writing)

You can make the person in the photo younger, change their gender, or turn them into a cat or an anime character. No difficult description is needed. Just fill in “① Characters” in 🧭 Guided writing as shown in the table below and press ✨ Format prompt.

What you wantWhat to enter in “① Characters” (example)Result
🙂 Animate the photo as it isOnly Gender “male” and Occupation “Japanese”. Leave Age empty, and leave “Non-human” and “Anime” untickedThe person in the photo moves and talks just as they are
🧒 Become youngerAge “16”, Gender “male”, Occupation “Japanese” (writing “high school student” in Features gets you closer)A 16-year-old look that keeps the facial features
🔄 Change genderAge “16”, Gender “female”, Occupation “Japanese” (put the hairstyle and outfit in “Features” and “What are they wearing?”)A female look that keeps the facial features
🌏 Change the look (appearance)Age “16”, Gender “female”, and a word that describes the look in Occupation (for example “Caucasian” or “Black”)The impression of the look changes while the facial features are kept
👶 Become a babyAge “0”, plus Gender and OccupationA 0-year-old baby
👴 Become 100 years oldAge “100”, plus Gender and OccupationA 100-year-old look with wrinkles and white hair
🐈 Become a catTick “Non-human”, Occupation “cat”, plus Gender (and for example “calico kitten” in Features)A lifelike cat from head to toe
🐱 Become an anime catTick both “Non-human” and “Anime”, Occupation “cat”A cat drawn in anime style
🎨 Turn the person in the photo into animeTick “Anime” (Gender and Occupation as they are for the person in the photo)A Japanese anime character whose face resembles the person
This does not reproduce what the person really looked like. When you transform someone by entering a number in the Age box (becoming younger, changing gender and so on), the app creates a new face of the age and gender you specify, based on features in the photo such as the eyes, nose, mouth and the outline of the face. It cannot know what that person's face actually looked like at 16. Think of the result as a different person, of another age or gender, who resembles the person in the photo.
When you change the age, gender or look, always enter a number in the Age box (the person's current age is fine). If Age is empty, the video is made with the look in the photo.
To begin with, try the sample JP_Mail_50.jpg (a 50-year-old man); the change is easy to see. The detailed steps are in 9. Handy tips, “⭐ With your own photo: ‘I want to look younger!’ …”.

③ Add a video as a reference for motion (only when you need it)

⚠ A reference video roughly doubles the video memory and time needed (it is processed together with the output, at the same size and length). When you use one, set the detail or the length to about half of what you usually use.

To use a video as the source of a “face and voice” rather than as a motion reference, add it to ① instead of ③ (→ the “What you add to ①” table above).

④ Choose the detail, length and quality

At first they can stay as they are (the starting values are detail 0.9, length 1 second, shape Landscape 16:9 and quality 20, which is “Speed”). If you are not sure, just press one of the purpose buttons under “Quality” (Fast preview to Best). For details, see 4. Detail, length and quality, and how long it takes.

⑤ Create the video

While a video is being created, close other apps that use the graphics card (games, video editing, video playback in a browser and so on). Leaving them open makes the video more likely to fail for lack of memory.

4Detail, length and quality, and how long it takes

This table shows at a glance which items affect the “time (⏱)” and the “video memory (🧠)”. If a video fails for lack of memory, lower a 🧠 item; to wait less, lower a ⏱ item.

The fast model for Turbo is installed together with the rest during setup. On a PC that still has an older setup, turning Turbo on downloads about 19.5 GB (the progress is shown next to “Turbo”).

When you add background music, set the length to 5 seconds or more

If the video is shorter than 5 seconds, it may come out silent even if you specify background music. This is because, among the official samples of the video AI (MiniMax H3), the ones with a photo, background music and spoken lines are made at 5 seconds, so 5 seconds or more is the guideline when you add background music.

Video length (seconds)

LengthWhen you add background music
🟥 1–3 secondsNot recommended. The music may be left out and the video may be silent. Use this to try out the look quickly.
🟨 4 secondsPossible, but there are few official samples with background music at this length, and the video may be silent.
🟩 5 secondsThe most recommended. The same length as the official samples with background music.
🟩 6 seconds or moreMakes it easier to combine background music, spoken lines and ambient sound.

When you use spoken lines, ambient sound and background music all together, 5–6 seconds works reliably. This caution also appears when you hover over “What about background music?” in Guided writing (from app 1.12.37).

Seed (Random / Same as last time / Custom value)

Even with the same description, the framing and motion change every time you create a video. The number that decides this is called the “seed”.

To enter a number yourself: just type a number in the box to the right of Seed. It switches to “Custom value” automatically. You can also edit the number shown by “Same as last time”. While the box is empty, you cannot press Create the video (from app 1.12.80).
When “Same as last time” cannot be chosen: if you have not created any video yet, or with an old history entry that has no recorded seed, you cannot choose “Same as last time” (use “Random” or “Custom value”). Once you have created one video, you can choose “Same as last time” from then on.

Even with the same seed, the result changes if you change the description, detail, length, quality, Turbo or photos. It is not for creating exactly the same video again; think of it as a way to get a similar feel.

Purpose buttons (under Quality)

ButtonWhat it setsWhen to use it
Fast previewTurbo on, quality 10When you want the fastest “preview” of the framing and motion. Not suitable for checking the finished look.
SpeedTurbo off, quality 20When you want to see a normal finish in a shorter time (this is the initial setting).
StandardTurbo off, quality 30Everyday use. A good balance between speed and how good the video looks.
HighTurbo off, quality 40When fine details, motion and a steady voice matter.
BestTurbo off, quality 50For the final finish.
Recommended flow: check the framing and motion with Fast preview → adjust the description → when you like it, re-create it with Standard or higher.

How long it takes

At the very bottom of the settings (under the Seed box) you see how long it will take. There are two kinds of estimate.

🆕 First-run estimateShown on a PC that has not created a single video yet. A rough figure calculated from the length and quality only (see the diagram below).
📈 On this PCAfter one video it switches to this. It is based on the time videos actually took on that PC, so it is more accurate. Example: “On this PC: about 6 min 50 sec (from 3 past runs with the same settings)”
Example of the first-run estimate: a length of 3 seconds gives three blocks of 2 min 10 s, quality 20 gives two, five in total, about 10 min 45 s ⏱ Length 3 s (one per second) ✨ Quality 20 (one per 10) Total 2 min 10 s 2 min 10 s 2 min 10 s 2 min 10 s 2 min 10 s = about 10 min 45 s
The first-run estimate is a sum: about 2 min 10 s per second of length + about 2 min 10 s per 10 of quality

5Using History

The “History” tab lists the videos you have created, newest first. Type a photo's file name, part of a description or a creation date (for example 2026/9/9) in the search box at the top to narrow the list.

ButtonWhat it does
▶ Play (or click the thumbnail)Plays the video.
🖼 ThumbnailsPick your favorite moment from the video. You can use that moment as the cover (thumbnail), or keep it as a photo with ⭐ Save to album.
🎬 Edit videoFound inside Thumbnails. Hide faces and other parts, lay mask images over it or delete frames you do not need, and save a video for sharing as a separate file (the original video stays as it is). For details, see “Edit video” below. You cannot press it while a video is being created (editing also uses the graphics card, so running both at once makes the generation more likely to fail).
📁 Save folderOpens the folder that holds the video.
View inputsShows a list of the photos, voices and reference videos used at that time.
🔁 Make it againBrings the same photos, description and settings back to the “Create” screen. What you typed in Guided writing comes back too. If the description was rewritten with ✨ Auto prompt, Undo brings back the text from before (what you typed yourself). Handy when you want to change a little and create again. The seed carries over the value that was actually used at that time, and “Same as last time” is selected from the start (switch back to “Random” if you want to change it).
🔁 Load these settingsBrings settings you kept with “💾 Save to history” back to the “Create” screen. What you typed in Guided writing comes back too.
📤 ExportWrites out a file for trying the same settings on another PC or in the cloud (for advanced users → 7. Export).
Copy descriptionCopies the description used at that time.
Delete entryDeletes that history entry. On the confirmation screen, choose “Remove from list” (removes it from the list only; the video file stays, so you can bring it back later from “Settings” → “History”) or “Delete the video too” (deletes the whole save folder; this cannot be undone).
Delete in a 🛡 For sharing rowVideos for sharing made with “Edit video” are listed one row each under the original video. You can delete just that one item (the original video is not deleted).

A failed entry keeps its “Failure details”. They are a useful clue when you contact support.

Edit video (hide faces, lay mask images, delete frames you do not need)

This screen hides “parts you do not want to show” in a finished video and removes scenes you do not need, to create one more video for sharing. The original video is not changed. All editing happens inside that PC only, and no video or image is sent anywhere.

How to open it: in “History”, press 🖼 Thumbnails for the video, then press 🎬 Edit video at the bottom left.

From top to bottom the screen has three levels: ① the video (the dotted oval is a “hidden place”) → ② the mask image strip and the frame strip (the upper row holds mask images laid in front of the video; the lower row is the video's frames laid out side by side, and striped frames are “frames to delete”) → ③ the row of buttons. Pick a moment on the strip, check it in the video, and edit with the buttons.

The first time you use “Sensitive body parts” or 🔞 Review mosaic, a screen asks to download detection data (about 12 MB). Press I have read the license, fetch it and it is ready from then on (the detection data for faces, people and license plates is included from the start). Your videos and images are never sent anywhere.

Step 1: Watch the video and pick a moment

What you wantHow
Play / pauseClick on the video to switch between play and pause each time (▶ and ❚❚ marks appear in the middle of the screen). The Space key does the same.
Go to the moment you want to seeClick the frame strip (or drag it). The moment you clicked appears in the video.
Move just a little← → move one frame at a time; hold Shift as well to move 0.5 seconds at a time.
See where things are hiddenTick ☑ Show hidden places to show outlines around the hidden places (it is ticked from the start). Untick it to see exactly how the published video will look.
Compare with the unedited videoSwitch between Processed and Original to check the original video too.

Step 2: Hide what you do not want to show

There are three ways to hide things. You can combine all of them (adding one later does not remove the earlier edits).

MethodHow to do it
🛡 Privacy blur
(finds places automatically)
In “What should be hidden?” choose Faces / Whole people / Sensitive body parts / License plates, set the Strength (Standard, Strong, Maximum) and press Auto process. It looks through the whole video and finds the places to hide automatically. To change how they are hidden (Blur, Mosaic, Black box), choose it under “Show advanced settings”.
🔞 Review mosaic
(for stores)
Choose the store (DLsite / FANZA Doujin) and the Strength (Recommended, Stronger) and press Auto process. The groin, anus and contact areas are hidden automatically. To hide the chest and buttocks too, add them under “Additional parts”. This is automatic processing that refers to each service's publishing standards; it does not guarantee that the video passes review.
Hide this too
(mark it yourself)
Press the button, then drag on the video to draw an oval around the place. Choose Hide it for (1 second around this moment / The whole video) and press Hide this place. Use it for places that were not found automatically.

You can review the hidden places with the following two drop-down lists.

Drop-down listWhat it does
Hidden places: NLists the places being hidden now (Face 1, License plate 2 and so on). Pick one to jump to the moment where that place first appears. For an edit you do not need, press Delete on the right to stop hiding it throughout the video (you can bring it back with “Undo”, which appears on the screen). You can do the same by clicking the outline in the video directly and pressing Remove this mask.
Scenes to check: NScenes where automatic detection judged that “something may not be fully hidden” (tracking stopped partway, it touches the edge of the frame, it appeared only for an instant and so on). Pick one to jump to that scene, then look and check with your own eyes. If there is no problem, press Delete to remove it from the list (the hiding stays as it is; this only marks the scene as checked).

Step 3: Delete frames you do not need

Things that got into the shot by accident and moments that went wrong can be removed frame by frame.

What you wantHow
Delete the frame you are looking atPress 🗑 Delete this frame. The Delete key also works (while a mask image is selected, Delete removes that mask image instead; click the frame strip to go back to deleting frames).
Bring back a deleted frameGo to that frame and press ↩ Keep this frame (pressing Delete again also brings it back). Undo all deletions brings them all back at once.
See how much you deletedDeleted frames are marked on the strip, and the number and length are shown, like “Frames to delete: 12 (0.5 s)”.

Step 4: Lay mask images over the video (cinemagraph / motion comic)

What motion comics are good for and tips for making them are in 🎞 Make a motion comic.

When you lay a partly transparent image (a mask image) in front of the video, the video moves only in the transparent parts. You can make a comic page where “only the panel being read moves” (a motion comic), or a photo where only one part moves (a cinemagraph).

How mask images work: lay a comic page with one panel made transparent in front of the video, and the video behind shows and moves only in that panel ▶ ▶ + Mask image (front)a panel made clear Video (back)moves as usual Resultonly that panel moves
The mask image sits in front of the video. The video behind shows only through the transparent parts
What you wantHow
Add a mask imageClick the dotted + Add a mask image (an empty space) just above the frame strip and pick an image. It fills that whole empty range (one image alone covers the whole video).
Line up one image per panelPick several images at once in the file window, and they are placed in file-name order (01, 02, 03…), splitting the empty range evenly. For a comic, prepare images with one panel made transparent each, in reading order, and those panels move one after another.
Make a mask image from this framePick a moment and press 🖼 Make a mask image from this frame to open the “Make a mask image” screen. Drag to surround the area you want to move (⬭ Oval / ▭ Rectangle), then press Make this area transparent (as many areas as you like; ↩ Undo one brings the last one back). Save turns it into a PNG and puts it in the last empty space of the strip (if there is none, the last mask image is halved and the new one goes after it; if the strip is empty, it starts at the beginning). Pressing ✕ Close before saving makes nothing.
Shift when it is shownDrag the mask image. When it bumps into another mask image, it pushes that one along instead of overlapping. Once they are packed against the start or end of the video, it stops. After selecting one, ← → also move it one frame at a time (0.5 seconds with Shift).
Change how long it is shownDrag the left or right edge of the mask image (mask images it bumps into are pushed along).
Change the imageDouble-click the mask image, or select it and press Change image (the range stays the same).
Remove itClick the mask image to select it, then press the Delete key or Delete. Only the selected mask image is removed (use Undo in the notice to bring it back).
Remake or remove it (right-click)Right-click a mask image on the strip to get ✏ Edit and 🗑 Delete. “Edit” opens that mask image on the “Make a mask image” screen so you can add more transparent areas (saving replaces it with a new PNG, and the range stays the same). “Delete” works like the Delete button.
Check how it looksIn the “Processed” view, the mask images are laid over the video both when it is paused and while it plays (the “Original” view does not show them). On the strip, the panels made transparent are painted purple.

Step 5: Save it as a video for sharing

AI can miss things. Before you publish a video, always watch it yourself from start to finish and check it.

🎞 Make a motion comic (bring comic panels to life one at a time)

A “motion comic” is a video of a comic page where only the character in the panel being read moves and talks. With this app, you can turn a single comic page into a vertical short video where the panels come to life one after another.

📱 A popular short-video formatIt is one of the “formats that can go viral” for vertical shorts on TikTok, YouTube Shorts and Instagram Reels.
📈 A million views is not rareComic-style short videos passing 1 million views are not unusual. Companies also use them in ads and promotions.
🔥 Anime and manga are huge on TikTokFor some works, related videos are viewed hundreds of millions to over a billion times.

Why use mask images?

Even if you ask the video AI (MiniMax H3) to “move only this panel”, when the same character's face appears several times on the page, the faces in other panels may move or lip-sync too. To the AI, every face looks like the same person.

That is where mask images help. When you lay a “still picture” with only the panel you want to move made transparent over the video, the video shows only inside that transparent panel and the other panels stay still. Prepare one mask image per panel, line them up in order, and you have a motion comic whose panels move one at a time.

How mask images work: without masks, the same character's face moves in two panels at once; with a mask image laid over the video, only the panel made transparent moves lay a mask image ❌ Without masks other faces move too ✅ With masks only one panel moves
The striped areas are the mask image (a still picture). Only the panel with the green frame shows the video behind and moves

How to make one (4 steps)

① Make a video from a comic pagePut the comic page in “① Reference pictures” and choose “Portrait 9:16 (phone)”. Describe the movements, expressions and lines in the prompt
② Open Edit video“History” → 🖼 Thumbnails → 🎬 Edit video
③ Make a mask image per panel“🖼 Make a mask image from this frame” → surround the panel to move → “Make this area transparent” → Save. Repeat for each panel in reading order
④ Check, save and postEven out the mask lengths on the strip and click the video to play it. After “Save video for sharing”, post it as a short!
TipsDetails
📚 Follow the reading orderJapanese comics are read from the top row to the bottom row, and right to left within a row. Make (and line up) the mask images in this order so the story flows naturally.
📷 Keep the camera stillIf the whole page zooms or shakes, the still picture (the mask image) and the video no longer line up. Writing “camera fixed” in the prompt helps.
⏱ About 2 to 3 seconds per panelFor a 10-second video with 4 panels, that is about 2.5 seconds each. New mask images go to the end of the strip (if there is no room, the last one is halved to make space), so finally drag the edges on the strip to even out the lengths.
🗂 Add image files at onceIf you have PNGs with one panel made transparent (one per panel), pick several at once with the dotted + Add a mask image on the strip, and they are lined up in file-name order, split evenly.
✏ Remake with a right-clickRight-click a mask image on the strip → ✏ Edit to add more transparent areas. 🗑 Delete removes only that mask image.
💾 Safe to close midwayMask images are remembered for each video. Close the screen, and next time you open “Edit video” you can continue where you left off.

For step-by-step operations, see “Step 4: Lay mask images over the video” in 5. Using History.

Use only comics and illustrations that you own the rights to or are allowed to use (→ 11. Using the app safely).

7Export (for advanced users)

The instructions and messages in exported files follow the Japanese or English language selected in Settings. Your prompts, material names and file names are kept as entered.

This chapter is for people who want to re-create a video on another PC or on a cloud service. You do not need it for everyday use.

📤 Export is a button that writes the settings you are using now (description, which photo is which, detail, length, quality and so on) into one file. Open the file in another environment and you can re-create the video with the same settings. It is not a button that exports the video itself (the video is in your save folder).

🎁 During the free trial you can open the export screen and check its contents. Export (writing the file) is a full-version feature.

The photo, voice and video files themselves are not included. Only the file names are recorded. In the other environment, add the files with the same names, as in the list shown on the screen. If a name is different, the file cannot be loaded.

Three kinds of files

FormatWhen to use it
🖥 ① For ComfyUI (standard)To open it in ComfyUI installed on your own PC. It works the same way as this app, so the result is the closest.
☁️ ② For ComfyUI (high quality)To re-create the video at a higher quality on the cloud service Floyo.
🌐 ③ For Google ColabWhen your own PC has no high-performance graphics card. It runs on Google's cloud and does everything automatically, from setup to creating the video.

How to use them

  1. ① ComfyUI (standard): copy the exported .json to the PC with ComfyUI, and put the photos and voices into ComfyUI's input folder with the same names. Open ComfyUI in a browser, drag and drop the .json onto the screen and run it.
  2. ② ComfyUI (high quality): open the ComfyUI screen on Floyo, drag and drop the .json, upload the photos and voices, and run it. If “Missing Models” appears, follow Floyo's guidance to get the parts.
  3. ③ Google Colab: in Google Colab, load the .ipynb from “File → Upload notebook”, choose a GPU (G4 is the best choice; if you cannot select it, A100) under “Runtime → Change runtime type”, turn on “High-RAM” if the option is there, and choose “Run all”. When it pauses partway, upload the photos and voices with the names shown. When it finishes, the video is downloaded to your PC automatically.

Choosing a GPU in Google Colab

A guide to which of the GPUs offered under “Change runtime type” suit this app. For video creation, the amount of video memory matters most (→ How do they compare with home cards?).

GPUFitWhy
G4◎ Best choiceAbout 96 GB of video memory (NVIDIA RTX PRO 6000 Blackwell). The full set of AI parts (about 42.5 GB) fits as it is, so the waits are the shortest.
A100◎Powerful and stable. However, on Colab it can be the 40 GB model, which has less video memory than G4, so some swapping happens.
L4○24 GB. It works, but there is a lot of swapping, so it takes time.
T4△ Not recommended16 GB. The standard T4 stops for lack of memory. Even with High-RAM it is very tight and takes a very long time.
You can start for free. Google Colab needs no sign-up if you have a Google account (however, G4, A100 and L4 are GPUs you can select on a paid plan such as Colab Pro. The free tier usually offers only the T4, which is not suited to creating videos). For Floyo, enter KATORI30 in the Promo Code box on the payment screen to try it free for 30 days. → 9. Handy tips

How do cloud graphics cards compare with home ones?

This helps you decide when “my own PC is too slow” or “I am not sure whether to buy a new graphics card”. The first thing to know is that what matters in video creation is “the amount of video memory” rather than speed.

The full set of AI parts this app uses is about 42.5 GB even in its smallest configuration. Whatever does not fit in video memory is calculated while being swapped to and from the PC's main memory each time, and that waiting makes it slower. Even the top home card has 32 GB of video memory, so a home graphics card cannot hold the full set of parts. This is the biggest difference from the cloud.

EnvironmentVideo memoryCompared with 42.5 GBWhat happens
Your own PC (this app's minimum)12 GBabout 30.5 GB shortIt runs, but with a lot of swapping, so it takes time. With a length of 1 second and one photo, you can try up to detail 2.
GeForce RTX 4090 (a high-end home card)24 GBabout 18.5 GB shortMuch faster, but the swapping remains.
GeForce RTX 5090 (the top home card)32 GBabout 10.5 GB shortAmong the strongest for home use. Even so, not everything fits.
Google Colab (L4)24 GBabout 18.5 GB shortThe same amount of video memory as the RTX 4090. However, its memory reads and writes at about one third of the 4090's speed, so the waits are longer.
Google Colab (A100 40 GB)40 GBabout 2.5 GB shortComes close to fitting everything.
Google Colab (A100 80 GB)80 GBabout 37.5 GB to spareThe full set of parts fits as it is. Hardly any swapping happens.
Google Colab (G4)96 GBabout 53.5 GB to spareThe most headroom among the GPUs Colab offers. It is an NVIDIA RTX PRO 6000 Blackwell, with the video memory of 3 RTX 5090 cards.
Floyo (H100 NVL)94 GBabout 51.5 GB to spareAs much headroom as G4. Its video memory equals about 2.9 RTX 5090 cards, and its memory reads and writes about 2.2 times as fast.

On a smartphone, you can scroll the table above sideways.

The larger the detail, the longer the video and the more photos you use, the more this difference shows. In order, they rank as follows.

RTX 4090 < RTX 5090 < Colab (A100 40 GB) < Colab (A100 80 GB) < Colab (G4) / Floyo (H100 NVL)

This does not mean “Floyo is 3 times as fast as the RTX 5090”. The figure of 2.9 cards compares the amount of video memory. The actual speed also varies with the detail, length and quality, and with how busy the service is that day. It is also a different thing from a ranking of gaming performance.

Which one should you choose?

💡 Could a GPU actually cost you less?
If the cloud charges JPY 100 per 10 seconds, 10 clips a day adds up to JPY 30,000 a month. On your own GPU, each clip costs only a few yen in electricity. For a few clips a month the cloud is fine, but the more you create, the more a GPU becomes the cheapest choice. → Could an expensive GPU cost less? (calculate with your own numbers)

Sources of the figures: the 42.5 GB full set of parts is from the official ComfyUI blog; Floyo's H100 NVL (94 GB, 3.9 TB/s) is from Floyo's official information; the RTX 5090 (32 GB, 1.792 TB/s), A100 and L4 (24 GB, 300 GB/s) are from NVIDIA's official specifications, and Colab's G4 (NVIDIA RTX PRO 6000 Blackwell, 96 GB) is from Google Cloud's official specifications (as of October 2026). Besides video memory, there are also differences in how AI calculations are done and in hardware generations, so please treat the comparison above as a guide.

When Google Colab stops or shows an error

Even if an error appears in red, the work done up to that point is kept. You do not need to start over. Press the ▶ to the left of where it stopped and run just that block (cell) again.

What you see on the screenWhat to do
NVIDIA GPU is unavailable.In the menu at the top, choose “Runtime” → “Change runtime type”, select a GPU (G4 is recommended; otherwise A100), and choose “Run all” again (→ Choosing a GPU).
Insufficient system RAMOn the same screen, turn on High-RAM or change the GPU to G4 or A100. The standard T4 is not enough.
It stops at the upload of photos or voicesChoose a file with the same name as the file name shown on the screen. You cannot go on if the name is different. Run the cell again to choose again.
Downloading the parts (AI models) stopped partwayRun the 04_Download_MiniMax_H3_models cell again. It skips what has already been downloaded correctly and fetches only what is missing.
“could not fetch”, “HEAD … does not match” or “installed versions differ”: a version mismatchUpdate this app to the latest version, then export again. An exported file remembers the versions of the parts that were verified to work at the time it was made, and is built not to switch to newer versions on its own (that way the same result can be re-created).
After you left it for a while, it went back to the initial stateGoogle Colab disconnects after a certain time and its contents are erased. Choose “Run all” again (it starts over from downloading the parts).

At the very bottom of the notebook there is also 10_Troubleshooting. Please take a look there first too.

If it still does not work (contacting support)

Prepare the following three things and send them to the support contact written in your purchase email. The cause can then be found quickly.

  1. The error text: copy the last few lines of the red text (the line that starts with “❌” and the lines below it are enough). A photo of the screen is fine too.
  2. The run log: press the folder icon at the left edge of Google Colab, right-click wishmallet_studio_export_report.txt and download it. The log up to the point where it stopped is saved automatically.
  3. The exported file: the .ipynb you used, itself. It records when and with which version it was made.

If the app itself also seems to be misbehaving, please also send the ZIP made with Save support information under “Settings” → “Support” (→ 10. Troubleshooting). It does not include photos, voices, videos, descriptions or your activation code.

Exported files go into the exports folder inside your save folder. In another environment the graphics card is different, so the picture will not be exactly the same. Lowering the length or detail makes failures less likely.

9Handy tips

⭐ Get a prompt for the video you want from just a few words (✨ Auto prompt)

Write the video you want to see in a few words and press ✨ Auto prompt. The AI rewrites it into a prompt (description) in the officially recommended format for making that video. No photos or voices are needed.

The AI plans scenes that fit the length and shape you set and fills out the description. Reading the result shows you how a description should be written to get the video you have in mind. Once you are used to it, add places, people, movements and lines, or add photos and voices, to get closer to exactly what you imagine.

Recommended steps

  1. Set the conditions first. To start, a very short video is best: Detail 0.5 / Length 1 sec / Shape Landscape 16:9 / Quality 20. It finishes quickly, so you can soon see whether your words become the video you imagined.
  2. In “② Describe the video you want”, write the video you want in a few words and press ✨ Auto prompt (30 seconds to 2 minutes; the first time takes a few minutes longer because the needed parts are downloaded).
  3. When the prompt is ready, press Create the video.

For example, you can start from words like these.

Tip: do not make one sentence too long. Keep writing short sentences separated by periods, and you are more likely to get the video you imagined (for example: A giant castle floats above the clouds. A flock of white birds flies over a beautiful girl standing at its entrance).

⭐ With your own photo: “I want to look younger!”, “I want to be an anime character!”, “I want to change my gender!”

All you need is one photo and 🧭 Guided writing. You do not need to write a description yourself. Start by setting the video length to 1–2 seconds so that you see the result quickly.

Common steps

  1. On the “Create” tab, press + Add and choose one photo in which the face is clearly visible. A photo of just one person, facing the front, from the chest up is recommended. You can also try the sample JP_Mail_50.jpg.
  2. Press 🧭 Guided writing at the top right of the description.
  3. Fill in “① Characters” as described for each goal below.
  4. In “Where are they and what is happening?” under “② Scenes”, write the place and the camera direction (for example: “They are sitting on a park bench. The camera shows the face from the front.”). Type a line in “What are they saying?” to make a talking video (it can be left empty).
  5. Press ✨ Format prompt, and when the description is ready, press Create the video.

“I want to look younger!”

  1. In “Age, gender and occupation?”, enter the age you want to be as a number only (for example 16), the gender (for example male) and the occupation (for example Japanese).
  2. In “Features”, a short note of the look you want gets you closer (for example high school student).
  3. Do not tick “Non-human” or “Anime”.

“I want to be an anime character!”

  1. Enter the gender and occupation as they are for the person in the photo (for example male and Japanese). Age can stay empty (if you enter it, the character is of that age).
  2. Tick “Anime”.
  3. With several people in the video, tick only the person you want as anime. The other people and the background stay as in the photos, and only that person becomes anime. Tick everyone and the whole video becomes anime.

“I want to change my gender!”

  1. In Gender, enter the gender you want (for example female).
  2. Enter a number in Age too (your current age is fine). If Age is empty, the video is made with the look in the photo.
  3. Write the hairstyle and outfit in “Features” and “What are they wearing?” to get closer to that look (for example long straight hair and high school uniform).
About the resulting face: a younger face or a face of another gender is a newly created face based on features in the photo such as the eyes, nose, mouth and outline. It does not reproduce the face you really had when you were young. Think of it as “a different person, of another age or gender, who resembles you”.

Other things you can do

What you wantWhat to enter in “① Characters”
👶 Become a babyAge “0”, plus Gender and Occupation
👴 See yourself at 100Age “100”, plus Gender and Occupation
🌏 Change the look (appearance)Age (for example “16”), Gender, and a word that describes the look in Occupation (for example “Caucasian” or “Black”)
🐈 Become a catTick “Non-human”, Occupation “cat”, plus Gender (and for example “calico kitten” in Features)
🐱 Become an anime catTick both “Non-human” and “Anime”, Occupation “cat”

The same list is also in 3. How to create a video, “Transform the person in one photo”.

When the change does not work well: (1) Check that a number is entered in the Age box (it is needed when you change the age, gender or look). (2) Add concrete details of the look you want to “Features”. (3) Set the seed to “Random” and create the video a few times.

When you use a photo of someone other than yourself, always get that person's permission (→ 11. Using the app safely).

⭐ Make a “motion comic” from a comic page

From a single comic page, you can make a vertical short video where only the panel being read moves and talks (a motion comic). It is a popular format that can go viral on TikTok, YouTube Shorts and Instagram Reels.

Even if you ask the AI (MiniMax H3) to “move only this panel”, other panels may move too when the same character's face appears several times on the page. Lay mask images, with only the panel to move made transparent, over the video in 🎬 Edit video, and the panels move one at a time.

⭐ I cannot write a good description

Press 🧭 Guided writing at the top right of the description on the “Create” screen. Just answer the questions and the description is written for you.

Tip: “Where are they and what is happening?” works reliably when you include the place, the time of day and the movement, one of each (for example: making coffee in a café in the evening).

⭐ I want to keep “one high-quality photo” without spending much time

Create a short 1-second video at good quality and keep one frame of it as a photo. It takes only a few minutes.

  1. Create a video with these settings: just one photo (no voices or reference videos) / detail 2 / length 1 second / any shape you like / quality 20 or more.
  2. Open 🖼 Thumbnails in “History”, drag the strip at the bottom to find a good moment, and press ⭐ Save to album.
  3. Open the photo in “Best shots”, press 💾 Save full quality and pick a purpose (not sure? “⭐ Master image”). The AI enlarges it to just the right size and saves it as a PNG (details in 6. Best shots). 🎁 During the free trial you can see the list of purposes and the preview.
Key point: normally a larger detail makes it easier to run out of memory, but with a length of 1 second and one photo, even a PC with 12 GB of video memory can create at detail 2. At quality 10 the picture may break down, so set the quality to 20 or more.

⭐ The video does not look good

  1. First, set the quality to Best and create the video again.
  2. If that is still not enough, raise the detail as far as you can. With a length of 1 second, even a low-performance PC can try up to detail 2.
  3. If it stops for lack of memory, buying a new graphics card is one option. But it is an expensive purchase, so before that, please also see “⭐ Try the cloud without spending money” below and 7. Export, “How do cloud graphics cards compare with home ones?”. Even if you upgrade to the top home card, the full set of parts does not fit.
    💡 On the other hand, if you create a lot, buying a GPU can cost less than paying for the cloud again and again → Could an expensive GPU cost less?

⭐ I want to re-create a video I like with a small change

You like the framing and motion, but you want to fix only the outfit or the spoken line, or raise only the quality. In such cases, use the “seed”.

  1. On the “History” tab, press 🔁 Make it again for that video.
  2. The settings come back to the “Create” screen, and the seed is set to “Same as last time”.
  3. Change only what you want to fix (the description, the quality and so on) and press Create the video.

You will not get exactly the same video. Think of it as getting close to a similar feel. Conversely, when you want to see various ideas from the same description, leave it on “Random”.

⭐ Try the cloud without spending money

Write out the same settings with 📤 Export and re-create the video on a cloud service (→ 7. Export). You can start both without spending money. See “How do cloud graphics cards compare with home ones?” for how powerful a graphics card you can rent.

ServiceHow to try it without spending money
Google ColabYou can start for free. With a Google account, you need neither a sign-up nor a credit card. However, G4 and A100, which suit video creation, are GPUs you can select on a paid plan such as Colab Pro. The free tier usually offers only the T4, so in that case use a paid plan or Floyo below.
FloyoYou can use the code KATORI30 to try it free for 30 days. Create an account, choose a plan under Pricing, and enter the code in the Promo Code box on the Checkout (payment) screen. The box does not appear on the screens before you choose a plan.

The Floyo code is the one published on Floyo's official site as of September 2026. It may end at the distributor's discretion.

10Troubleshooting

Look for the heading that matches. On every screen, “How to fix it” with numbered steps appears under an error; start by following those.

🩺 “Check the video engine” does not reach “Ready”

For each item shown on the screen, the way to fix it appears as numbered steps. Work through them from the top.

🚫 “Create the video” cannot be pressed

🧠 Videos fail for lack of memory

  1. Close other apps that use the graphics card (browsers, games, video players and so on).
  2. On the failure screen, press Try again with detail … (lowers the detail) or Try again at … seconds (shortens the video). The “…” is the value the app proposes.
  3. Reduce the number of photos. With a reference video, use about half your usual detail or length (a reference video needs about twice the memory).

🧩 “Guided writing” or “Auto prompt” stops with an error about a missing component

  1. Open “Ubuntu” from the Start menu.
  2. Type sudo apt install build-essential and press Enter (the password is the one you set when you first set up Ubuntu).
  3. When it finishes, go back to the app and try again.

Even if this feature is unavailable, it does not affect creating videos. If you are in a hurry, the link “just translate into English with Chrome”, which appears under ② with this error, also lets you go on (Google Chrome is needed).

📝 “The description is too long to translate and convert into the MiniMax H3 official format here.” appears

It exceeds what the formatting AI in this app can handle at once. Repeating the same long description in every scene reaches the limit quickly.

  1. Shorten the description, or write the parts repeated in every scene only once, and try again.
  2. To use it as it is, press 📋 How to convert it with ChatGPT or Gemini under the error, copy the text that appears with 📋 Copy and paste it into ChatGPT or Gemini. Paste the resulting text into the description box, then press Create the video.

⚡ “Create the video” cannot be pressed even though Turbo is on

If the fast model for Turbo is not on this PC yet (for example, a PC with an older setup), about 19.5 GB is still being downloaded. The progress is shown next to “Turbo”; please wait until it finishes.

🌐 “The remaining free videos could not be checked” appears

During the free trial, the number of videos is counted on our server. Check that you are connected to the internet and press Check again.

🔄 The update fails

Check that you are connected to the internet, wait a while, and then try “Settings” → “Updates” → Check now.

📤 An exported file gives an error in another environment

How to fix Google Colab when it stops, and what we would like you to send us, are summarized in 7. Export, “When Google Colab stops or shows an error”.

💾 “Save full quality” fails

  1. Close other apps that use the graphics card, such as games or video playback.
  2. Press Stop now under “Settings” → “⏸ Auto shutdown of the video engine”, then try again.
  3. If it still fails, update the NVIDIA driver.

If it says “The files for AI enlargement are missing.”, reinstall the app (run the installer again). Until then, you can still save a PNG with the “📷 Original size” purpose.

📮 If it is still not solved

Under “Settings” → “Support”, write what the problem is and press Save support information. Attach the ZIP file it makes and contact the support address written in your purchase email.
