Features
Why Seedance 2.0 Fast
Sub-minute turnaround on shorts
A 6-second 9:16 Fast clip is usually back before you've finished reading the prompt back. Built for creators publishing every day.
TikTok-native framing
9:16 is the default. Fast is tuned on the kind of motion and timing that tracks well on short-form vertical feeds.
Draft-to-delivery pipeline
Use Fast to explore 10 versions of an idea, then promote the winner to full Seedance 2.0 for the hero cut. Idea-cost drops dramatically.
Lower credit cost per clip
Fast consumes fewer credits than standard Seedance 2.0 per generation. On a Sunra subscription, the same weekly allowance covers 2-3x more drafts — the cheapest way to explore ideas in AI video.
Image-to-video at draft speed
Upload a product shot or a still from Sunra's image generator and Fast animates it in seconds. Test motion directions and camera angles before committing to a full-quality Seedance 2.0 render.
Stable character identity
Fast inherits Seedance 2.0's character consistency — faces, outfits, and proportions stay locked across the clip. No mid-frame drift, even at accelerated render speed.
