Seedance 2.0 Fast keeps the same three workflows as the standard tier: text-to-video, image-to-video with an optional end frame, and reference-to-video with image, video, and audio references. Use it when you want shorter iteration loops, faster A/B checks, and a lighter draft tier before you commit to standard Seedance 2.0.
Best for Storyboard passes before standard runs, Quick route comparisons across Seedance Fast, Veo Fast, and LTX Fast, and Quick timing checks for audio-led shots.

Why Seedance 2.0 Fast matters
Optimized fast variant (Fal lists Fast as the optimized route inside the Seedance 2 endpoint family)
Same workflow family (Text-to-video, image-to-video, and reference-to-video stay available in the same Seedance 2 stack)
Native audio plus multimodal references (Fast still sits inside the same audio-native and multimodal Seedance family)
Comparison-ready (Pairs naturally against Veo 3.1 Fast and LTX 2.3 Fast)
Built for escalation (Move successful drafts into standard Seedance 2.0 for polished finals)
Seedance 2.0 Fast works best when each run tests one decision. Keep the brief in Subject -> Action -> Camera -> Style order, then choose the fastest route: text, start/end image, or references.
Tip: duration + aspect ratio are set in the UI — your prompt controls subject, action, camera, lighting, style, and sound.
Text-to-video test prompt
Use when you want a fast read on framing, motion, or mood from language alone.
Text = test the brief itself.
Template (copy/paste)
Subject:
[Who/what appears]
Action:
[One visible beat only]
Camera:
[One short move]
Style:
[Lighting + palette]
Goal:
[What this run is proving: timing / framing / motion / audio]
Rule:
Do not combine multiple decisions in the same Fast run.
Example
Handheld smartphone UGC clip of a woman unboxing a new skincare bottle at a kitchen table. She peels the seal, smiles, and turns the bottle toward camera. Soft window daylight, natural colors, subtle room tone + packaging crinkle.
Image-to-video transition test
Use when you need to validate how a start frame lands on an end frame.
Start/End = test the transition and landing frame.
Template (copy/paste)
Start image:
[What is fixed from frame 1]
End image (optional):
[What the last frame should land on]
Motion path:
[How the subject travels between the two]
Camera:
[One move only]
What should stay identical across versions:
[Lighting / wardrobe / background / pace]
Use this when the question is transition quality, not final polish.
Reference continuity test
Use when you are checking whether the same reference pack holds together across variants.
References = test continuity with the same source pack.
Template (copy/paste)
Prompt intent:
[What the short draft should prove]
Image refs:
@Image1 = [identity]
@Image2 = [product / wardrobe / palette]
Video refs:
@Video1 = [camera rhythm / pacing]
Audio refs:
@Audio1 = [ambience / beat / dialogue texture]
Variant under test:
[Only one variable: camera / pace / framing / sound]
Rule:
Keep the same source pack while changing one thing.
Comparison / handoff prompt
Use this when Fast is selecting a winner before the standard tier.
Compare = package the winner for standard Seedance 2.0.
Template (copy/paste)
What stays fixed across A/B:
[Subject / refs / setting / duration / ratio]
Variant A:
[Camera / pacing / sound choice]
Variant B:
[One changed variable only]
Winner criteria:
[What counts as success]
If approved, move into standard Seedance 2.0 with:
[Extra polish, richer sound design, fuller shot plan]
