Seedance 2.0 Fast
The speed-optimized Seedance 2.0 variant — same director controls, faster turnaround for previews and iteration.
About this model
Seedance 2.0 Fast shares the Seedance 2.0 architecture — text-to-video, first/last frame, omni-reference, and optional audio generation — but prioritizes throughput over maximum resolution. It outputs at 480p and 720p, making it ideal for testing motion direction, camera language, and reference combinations before spending credits on a full 1080p Seedance 2.0 render. On HiArt, use Fast as the video equivalent of a rough comp: iterate on the canvas, then promote the winning prompt to Seedance 2.0.
Best for
- Same three modes as Seedance 2.0: text-to-video, first/last frame, omni-reference
- Faster generation for rapid motion preview cycles
- 480p and 720p output — lighter files for review and client sign-off
- Optional native audio generation for timing tests
- Omni-reference support for combined image, video, and audio inputs
- Lower credit cost per iteration than full Seedance 2.0
Common workflows
- Motion previews before final 1080p delivery
- Testing omni-reference combinations cheaply
- Client review loops for pacing and camera direction
- Storyboard animatics synced to a temp audio track
- A/B testing multiple motion prompts on the same still frames
How to use on HiArt
- 01Start with Seedance 2.0 Fast on a video node when exploring motion ideas.
- 02Use the same references and prompt structure you plan for the final render.
- 03Review at 720p, adjust prompt and references, and regenerate quickly.
- 04Once approved, switch the node to Seedance 2.0 and render at 1080p with audio enabled.

FAQ
- Does Seedance 2.0 Fast have fewer features than Seedance 2.0?
- No — the modes and reference limits are the same. The difference is output resolution (480p/720p only) and faster, lower-cost iteration.
- Can I preview audio with the Fast variant?
- Yes. Enable audio generation to test dialogue timing and rhythm before committing to a full-quality 1080p render.
