Seedance 2.0 FastWhat Seedance 2.0 Fast Can Do for Your Drafts
Test an Idea Before You Build It Out
Rough out an opening, swap the angle, or rework the last beat. Fast is tuned for shorter waits, so you can try several versions of a scene in one sitting. Sample from ByteDance's Seedance 2.0 family, not confirmed Fast output.
Spell Out the Movement You Want
Say what moves, where the camera travels and where the shot lands. A short clip is enough to check a reveal, a follow shot or a cut between two moments. Sample from ByteDance's Seedance 2.0 family, not confirmed Fast output.
Steer the Scene with Your Own Media
Begin with a still, or switch to reference to video and add images, clips and audio. Your references show the model the look, place and motion you have in mind. Sample from ByteDance's Seedance 2.0 family, not confirmed Fast output.
Add Sound in the Same Pass
Turn on audio and write the sound into your prompt: a line of speech, room tone, footsteps, rain. You then judge picture and sound together instead of in separate steps. Sample from ByteDance's Seedance 2.0 family, not confirmed Fast output.

Seedance 2.0 Fast Pros and Cons
A plain look at where Fast helps and where another Seedance model may suit you better.
Pros
Built for shorter waits — Fast is the lower-latency take on Seedance 2.0, which helps when you want many drafts in a row.
Three ways in — Text to video, image to video and reference to video all run on Fast, so you can start from whatever you already have.
Start and end frames — Image to video takes a first frame and an optional last frame to guide where the shot ends up.
Sound when you want it — Audio is an option, not a default. Leave it off for silent tests or switch it on to hear the scene.
Cons
Tops out at 720p — There is no 1080p option. Seedance 2.0 and Seedance 2.5 offer 1080p if you need a sharper master.
15-second limit — Each clip runs 4 to 15 seconds. Seedance 2.5 goes up to 30 seconds for a longer scene.
Wait time is not fixed — Speed is the design goal, but finish time depends on demand and on your request. There is no guaranteed turnaround.
