Seedance 2 Fast turns anime, action and one-take camera ideas into 720p clips with sound you can post today, at about four-fifths of Seedance 2.0's price.
Every model below runs on the same credit balance, so one prompt can go up against a rival in two clicks.
Posted on X by the people who made them, with the model named: bodies moving fast, anime that holds together, a camera that never stops.
Creators who build shorts from a storyboard and reference images work in this order.
Generate your character or product with an image model, then attach it to the shot.
One line per beat: 0–2s, 2–4s and on. Say what moves and what the camera does.
A 6-second 480p run is 350 credits: find the camera path and the action there.
Run the winning prompt again at 720p, 745 credits for six seconds, sound included.
Run it in your browser: no subscription tier to unlock it, no app region to switch, no graphics card to buy and nothing to install. ByteDance keeps the weights private, so this is how you skip the local setup.
Creative engine
Write the scene, or attach one or two images to hold a character, a product or a look.
Pick 4, 6, 8 or 10 seconds at 480p or 720p. Audio comes back in the same pass.
The estimate updates as you change length and resolution; the number you see is the number you pay.
Two of the Fast prompts shared on r/seedance2pro, a floating library and a room that renovates itself, are built around one continuous shot. This clip glides through a rabbit's treehouse down to a cooking fire in eight seconds.
Every step lands here: the camera tracks a dancer's footwork on a wet neon street, then circles out to the skyline. The Fast vs Pro fight test on r/aivideo drew about 180 upvotes.
The most-upvoted Fast post on Reddit is a retro anime short with more than 650 upvotes, and one reply asks how the shots stay so consistent. This cooking montage keeps one cook and one art style from egg coop to plated meal.
Prompt requests fill the replies under the best Fast clips on Reddit: "please provide prompt". Here is a creator's own, word for word, beside the video it made.
Three sentences, and the clip still gets the splash, the birds and the frozen rain.
A street musician plays a violin in the middle of a busy city. As the music begins, time freezes—birds stop mid-air, rain hangs motionless, cars freeze, while only the musician continues walking through the silent world. Cinematic camera work, emotional lighting, hyper-realistic, movie-quality visuals.

The matchups people ask about, with the differences as they stand on Kavel.
Same prompts, lengths and 480p or 720p for about four-fifths of the credits. The full model adds 1080p, end frames, multi-shot and a sound switch. One tester picked Fast outright for photorealistic shots.
See Seedance 2.0“I preferred seedance fast to the 2.0 even before enhanced fast for photorealistic stuff”
Both run 480p or 720p from text or images. A tester who ran both gives Fast the edge on realism and morphing; Mini is the lighter spend at about three-fifths of the price.
See Seedance 2 Mini“Fast tends to have better overall quality in terms of realism and less morphing compared to Mini.”
Seedance 2.5 runs up to thirty seconds at up to 1080p. For a clip of the same length at 720p, Fast costs about half as much, so a film cut from short shots gets nearly twice the takes.
See Seedance 2.5"Any similar model that can be ran locally?" comes up under Seedance comparisons. Nothing to install here, and one reply in the Fast vs Pro fight thread put it plainly.
“Fast remains superior to any local model.”

You can start free: log in and Kavel adds free credits, no card, to test an idea on Kavel's own video engine. Seedance 2 Fast runs on any paid plan or credit pack, with the cost shown before you generate.
A 6-second clip is 350 credits at 480p and 745 at 720p, sound included. The cheapest run is 235 credits for four seconds at 480p; the longest, ten seconds at 720p, is 1,240.
It renders 480p or 720p. When a shot needs 1080p, run the same prompt on Seedance 2.0 or Seedance 2.5 from the same credit balance.
Each clip runs 4, 6, 8 or 10 seconds. For a longer piece, generate it shot by shot and keep the same reference image and character description in every prompt.
Fast takes the same prompts and images at 480p or 720p for about four-fifths of the price. Seedance 2.0 adds 1080p, an end frame, multi-shot prompts and a sound on/off switch.
Yes. Every clip comes back with audio generated in the same pass, and the audio adds nothing to the credit price.
Yes. Switch to image to video and attach one or two images, then describe the motion and the camera. The image holds your character, product or style through the clip.
No. A run that fails puts its credits back in your balance automatically, unless the prompt broke the content policy.
Paste a creator's prompt or write your own beats and get a 720p clip with sound for a fifth less than Seedance 2.0, exact credit cost in view before you press generate.
