What is Seedance Pro Fast
Seedance Pro Fast is ByteDance's fast image-to-video model from the Seedance 1.0 line, released in 2025. The base Pro version of this line once topped independent video generation rankings, and Pro Fast is its accelerated variant: it generates noticeably faster and cheaper at close picture quality. The word Fast here means a priority on speed, not cut-down resolution.
The model works as image-to-video: you upload a single frame and Seedance Pro Fast animates it, giving motion to the object and scene. That sets it apart from the newer Seedance 2.0 line, which adds native audio, multimodal references and first- and last-frame control. Pro Fast focuses on one thing: quickly and cleanly turning a static image into a short clip.
An important difference from the 2.0 generation is the absence of audio. Like the whole 1.0 line, Pro Fast creates a silent video. In return it offers resolution up to 1080p and high speed, which makes it handy for storyboards, product inserts and batch work where you need to quickly go through many frames. For finer control there is a camera fix: it keeps the frame static when only the object should move.
On Genosai the model runs online: you do not need a developer account, API keys or your own infrastructure. You open the video studio in the browser, upload a frame, describe the desired motion, and get a short clip. Seedance Pro Fast suits anyone who values speed and a clean picture without sound: marketers, storyboard authors and everyone who animates ready images in volume.
Capabilities
Seedance Pro Fast focuses on fast, high-quality frame animation. Here is what the model does in practice.
Image-to-video
The model's key mode is animating a single uploaded image. You pass a frame and describe how it should move: a subtle camera dolly, an object turn, wind in frame or character motion. The model keeps the composition of the source and adds dynamics to it, turning a static photo into a short clip.
Resolution and duration
Seedance Pro Fast generates at 480p, 720p and 1080p, so it fits both fast drafts and a clean final clip. Duration is 3 to 10 seconds: enough for inserts, storyboards and short scenes. Different aspect ratios let you assemble a clip for a horizontal, vertical or wide frame; motion comes out best when the format matches the source image.
Speed and cost
Pro Fast's main strength is speed. It is the accelerated tier of the 1.0 line: it generates noticeably faster and cheaper than the regular Pro version at close quality. Because of that the model is handy for batch work — when you need to animate a dozen frames and pick the best, without spending time and budget on a slow render.
Camera fix
For control over dynamics there is a camera fix. When it is on, the frame stays static and only the object in it gets motion. This is handy if you want to animate, say, a waving flag or a character's expression but do not want the camera to fly around the scene. The effect depends on the source, so it is worth checking the result on a specific frame.
Examples
There is no demo gallery for Seedance Pro Fast on Genosai yet, so instead of ready clips we describe the typical scenarios the model is built for. The first scenario is animating a product photo: you upload a shot of an item and set subtle motion — a slow turnaround, a highlight, a camera move around the object.
The second scenario is a portrait or character: you animate a static frame by adding expression, hair motion or a slight head turn. The third scenario is a storyboard: you quickly run a series of frames through Pro Fast to see how each scene comes alive in motion and pick the good ones. The fourth scenario is a landscape or atmospheric frame with a fixed camera, where only water, clouds or fire move. In all cases the model generates a silent video at up to 1080p.
How to use on Genosai
Launching Seedance Pro Fast on Genosai requires no setup: everything happens in the browser and the model is already connected. The basic path from a frame to a finished clip looks like this.
- Sign in to your Genosai account and open the video studio.
- Pick Seedance Pro Fast in the model list.
- Upload the source frame you want to animate.
- Describe the desired motion: a camera dolly, an object turn or motion in frame.
- If needed, turn on the camera fix and set the resolution and duration.
- Run the generation, then download the clip or refine the prompt and repeat.
Prompts
These templates show how to phrase tasks for Seedance Pro Fast. Replace the text in square brackets with your own data and describe the motion specifically — the model adds it to the uploaded frame.
Animate the product frame [description]: slow object turnaround, subtle highlight, camera slowly moves in, 1080p.Portrait [description]: light expression, hair motion, calm head turn, keep the composition.Landscape [description] with camera fix: only water and clouds move, static frame, 720p.Storyboard: animate the uploaded frame [scene], a short camera move [dolly/zoom], 5 seconds.Atmospheric frame [description]: slow smoke and light motion, soft dynamics, no sharp moves.Product insert: [product] on [background], camera arcs around the object, clean light, 720p.Character [description]: a light step forward, natural gait, fabric motion, 10 seconds.Generation cost
On Genosai the cost of Seedance Pro Fast depends on the resolution and duration of the clip and is on average from 18 to 72 credits per generation. A short clip at a low resolution is closer to the lower bound, and a longer one at 1080p closer to the upper. You pay for actual generations, with no monthly subscription, so the spend is easy to plan for a task.
As the accelerated tier of the 1.0 line, Pro Fast is noticeably cheaper than the regular Pro version, so it is handy for batch work and storyboards. Starter credits after sign-up let you try Seedance Pro Fast for free. Current packages and balance are in the Pricing section.
Comparison
Seedance Pro Fast is the choice when you need to quickly and cleanly animate a ready frame without sound. If you need a clip with audio, references and frame control, move up to the 2.0 line: the fast Seedance 2.0 Fast or the flagship Seedance 2.0. Within the older 1.0 line there is the cheaper Seedance V1 Lite, and among other families Veo 3.1 Fast is close in class.
| Model | Strength | Price on Genosai |
|---|---|---|
| Seedance Pro Fast | Fast i2v up to 1080p, no audio | from 18 to 72 credits |
| Seedance V1 Lite | Cheapest i2v of the 1.0 line | from 2 credits/sec |
| Seedance 2.0 Fast | Audio and references, up to 720p | from 15.5 credits/sec |
| Seedance 2.0 | 1080p and audio, top quality | from 9 credits/sec |
| Veo 3.1 Fast | Fast video at high resolution | 720p=60, 1080p=65 |
All models are available in one Genosai interface, so you can compare them on your own frame and pick the best by price and quality. A practical approach is Pro Fast for fast frame animation without sound, and moving to the 2.0 line for scenes with dialogue and effects.
Limitations and tips
Seedance Pro Fast belongs to the earlier 1.0 generation, so it has no audio, no multimodal references and no first- and last-frame control — all of that arrived in the 2.0 line. If you need a clip with sound or fine control over the scene, use Seedance 2.0 Fast or Seedance 2.0. The exact set of available parameters may depend on the studio — rely on the actual result.
Since this is image-to-video, the clip quality depends heavily on the source frame. Upload a clean image without extra noise, and match the clip format to the source aspect ratio — that way motion comes out more naturally. Describe the motion specifically: the clearer what should move and how, the more predictable the result. For scenes where the camera should stay put, turn on the camera fix.
Work iteratively and use the model's main advantage — speed: run the frame at a low resolution, check the character of the motion, then regenerate at 1080p for the final. That way you save credits and reach the result faster, without spending the budget on slow takes.
