Seedance 2.0 Extend Video: Make Short Clips Last Longer (Without Melting)
Seedance 2.0 extend video is useful when a 3s hero needs a 6s ad beat. I extend on Seedance 2.0 only after the first seconds are clean.
TL;DR
| Situation | Move |
|---|---|
| Strong first 2–3s | Extend carefully |
| Already morphing | Cut; regen from last good frame |
| Need new camera idea | First/last frame beat instead |
| Looping PDP | Prefer designed loop over blind extend |
Practical rules
- Extend from a stable last frame.
- Keep camera language the same.
- Don’t stack three extends hoping chaos settles.
Pair with first/last frame when the beat must land on a pose.
