How to Make an AI Animated Short Where the Characters Stay Themselves: Design in Stills With Krea 3, Animate With Seedance 2.5
Watch enough AI animation and you start to notice what goes wrong. It is rarely the motion. It is the slow drift: the jacket changes colour between shots, the hero's face gets a little rounder each scene, the background trades a flat illustrated style for something glossy and photographic halfway through. Each clip looks fine alone. Cut together, they look like six films by six artists.
A short called No Ordinary Love, by an artist who posts as antrofrog, does not have that problem. It runs about a minute, moves through roughly ten settings, and its two leads look like the same two people from the first frame to the last. Krea published a breakdown of how to make a film like it on November 2, and the method underneath is simple enough to state in one sentence.
Decide everything in still images. Then ask the video model to do one small thing at a time.
That sounds obvious. Almost nobody works this way, because typing a scene into a video model and watching it come alive is so much more fun than painting ten background plates first. The fun is exactly what causes the drift.
Why stills first works
A video model is asked to invent a lot at once: what the character looks like, what they wear, what the room looks like, how the light falls, what happens, and how the camera moves. Every one of those is a chance to make a different choice from the last clip.
When you start each clip from a finished still, most of those choices are already made. The costume, the palette, the line weight and the setting are all in the frame. The video model only has to answer "what moves, and how." Fewer open questions means fewer places for the film to wander.
Krea's guide puts it in one line worth taping above your desk: "Let the still carry the suit and the dress."
It is also cheaper. Fixing a face in a still takes seconds. Fixing a face that has drifted across four generated clips means regenerating all four.
The tools, and what antrofrog actually used
Be clear about what is known here. antrofrog credits his tools: Midjourney 8.2 for one lead, George, and Krea 3 for the other, Gina. He has not published his prompts, shot list or settings. Krea's article fills in a recommended method around those credits, and it is Krea's own guide to its own tools, so read it as a vendor recipe built around a real film rather than a transcript of how the film was made.
The two tools in the recipe:
Krea 3 is Krea's image editing model. It can take up to 8 reference images in one edit, which is what lets you say "put this character into this room, in this style." It has three modes. The guide recommends fast for trying poses, high for the still you will actually animate, and ultra for looser instructions. Most edits finish in under 8 seconds at 2K resolution, the guide says, while ultra can take several minutes.
Seedance 2.5 is ByteDance's video model, available inside Krea. It can animate from a start frame or from reference images, makes clips from 4 to 30 seconds, and can generate sound along with the picture.
Put this into practice: the six-step recipe
This is Krea's recommended method, tightened into a sequence you can follow for your own short.
1. Write the beats before you make a single image. No Ordinary Love moves through six story beats in about a minute. Write yours as one line each: who, where, what happens. If a beat needs dialogue, rethink it. The film has none, and that is a big part of why it works (more on that below).
2. Design each character as a single hero still. Make one clean, front-facing image per character in the costume they will wear for the whole film. Use whatever image tool you like; antrofrog used two different ones. Save these images. They are your character references for everything that follows.
3. Paint every setting in one flat style. Krea's suggestion is to make all the backgrounds first, in a single consistent look, before any character goes into them. Same palette, same line weight, same level of detail. Lay all ten thumbnails side by side. If one looks like it came from a different film, redo it now, while it costs seconds.
4. Place the characters into the plates with Krea 3. For each shot, give Krea 3 the background, the character reference, and one example image of your style, then describe the pose. Use fast mode to try poses and high mode for the keeper. You now have a start frame for every shot. Krea notes that dedicated style references for Krea 3 are "coming soon," so for now that single style example image is doing the work.
5. Animate each start frame with one action and one camera move. In Seedance 2.5, keep each clip to 4 to 8 seconds. The guide is specific: one action, one camera move, ambient sound only, mouth closed. "She turns toward the window, slow push in, rain on glass" is a good prompt. "She walks across the room, picks up a letter, reads it and starts to cry while the camera circles" is four clips pretending to be one.
6. Draft cheap, then finish. Generate at 480p first. When a take has the right timing and staging, render that one at full quality. Then cut the film in your editor and lay the music in there, not in the video model. Krea also offers plugins for Premiere Pro and After Effects if you want to generate a replacement shot without leaving your timeline.
The small rules that do a lot of work
A few details in the guide look minor and are not.
Closed mouths. Asking for a closed mouth sidesteps lip sync entirely. Generated mouths that do not match words are one of the fastest ways an AI film loses its audience. A dialogue-free film with music sidesteps the problem rather than fighting it.
Ambient sound only. Seedance can make sound with the picture. Ask it for rain, footsteps and room tone, and add the music yourself in the edit. That way the soundtrack stays continuous across cuts instead of restarting with every clip.
Four to eight seconds. The model can go to 30 seconds. Longer clips give it more time to change its mind about the character. Short clips with one action each are easier to judge, cheaper to redo, and cut together more cleanly.
Illustrated, not photoreal. Krea blocks uploaded images and video that show realistic human faces, which is one reason the guide works from illustrated frames. It also happens to be the style where consistency is easiest to see and easiest to hold.
What it costs
Seedance 2.5 on Krea needs the Pro plan or higher. Krea's pricing page lists Pro at $35 a month, dropping to $21 a month with yearly billing, with 20,000 compute units a month. Krea does not publish a clear per-clip price on that page, so the honest way to budget is to draft at 480p and watch your unit balance for the first few shots before committing to the whole film.
The bigger cost is time, and the recipe moves it. You will spend longer on stills than you are used to, and much less time regenerating video that drifted.
Where it breaks
This is a reconstruction. The creator did not publish his process. You are following Krea's best guess plus his tool credits, not his notebook.
Faces still drift. Krea's own technical report for Krea 3 says it "is not perfect at preserving identity across edits." Starting every clip from a still reduces drift. It does not remove it. Check every start frame against your hero still before you animate it.
Small text is still weak. The same report says very dense small lettering is still imperfect. Shop signs and handwritten letters in your settings may need fixing by hand.
No dialogue, by design. The method avoids talking because talking is where it breaks. If your story needs characters to speak on camera, this recipe gets you the look but not the performance.
Music rights are on you. No Ordinary Love is set to a copyrighted song, and Krea's guide tells you to use music you own or have licensed. It also advises against attaching commercial recordings as sound references in Seedance. If the film is for a client, a festival or a monetised channel, clear the music first.
A paid plan and a vendor's word. The animation step needs Krea Pro, and the speed figures above are Krea's own. Nobody independent has published timing tests for this exact pipeline.
The habit worth keeping
You do not have to use Krea to use this idea. Any image tool that takes references and any video model that starts from a frame will reward the same discipline: settle the look in stills, keep the clips short, give each one a single job, and leave the soundtrack to the edit.
Pick one beat of a story you have been meaning to make. Paint its setting, place one character, and animate six seconds of it. If that clip looks like it belongs in the same film as the still you started from, you have the method. The other nine scenes are just more of the same.
