- You render 8-second scenes — Sora's baseline matches typical UGC scene length
- Cost is your primary constraint and you can work with chained renders
Choose Seedance 2.0 if…
- You want cinematic realism with high-quality scene composition
- You need both text-to-video and image-to-video paths in a single engine
- You render short 4-second scenes where Seedance's baseline is the natural fit
- You want HQ output at a similar price to Sora HQ (70 cr vs 65 cr per 8s scene)
