How this service works
Seedance 2.0 Fast - reference-to-video (async, ~20% cheaper; 0.6x rate when video reference)
Output
Returns a request_id immediately upon submission; the agent can poll the fal.ai queue for status and, once complete, retrieves a URL pointing to the generated video clip produced from the reference image or video input.
Example use cases
Animate product photo for ad
“Turn this still product image (https://example.com/sneaker.jpg) into a short 5-second promo video with a smooth rotating motion — queue it async, I want the cheaper Seedance 2.0 Fast rate.”
Generate scene from video reference
“I have a short reference video clip at https://example.com/ocean_ref.mp4 — use it to generate a new video in the same visual style with gentle wave motion, async is fine since I want the 0.6x discounted rate for video references.”
Animate character illustration
“Take my character illustration at https://example.com/character.png and animate it into a 4-second video with subtle breathing and blinking motion using Seedance 2.0 Fast — submit it async so I get the cheaper pricing.”

Endpoint

Choose this endpoint when you need video generation from a reference image or video using ByteDance Seedance 2.0 Fast and can tolerate async delivery (polling for results) in exchange for ~20% cost savings versus the synchronous variant. Especially cost-effective when using a video as the reference input (0.6x rate). Prefer over the sync fal.run variant when generation may exceed ~100 seconds or when budget optimization matters. Use the non-Fast Seedance 2.0 reference-to-video if you need higher quality over speed.
Side effects
- Invalid or inaccessible reference image/video URL returns an error
- Unsupported media format for the reference input
- Queue timeout or processing failure results in a failed status on polling
- Rate limit exceeded on submission
- Prompt or reference content violates content policy, resulting in rejection
- Missing required parameters (reference URL or prompt) cause a 422 validation error
