Frequently asked questions
How is Seedance 2.5 different from 2.0?
2.5 makes videos up to 30 seconds (2.0 — 15s), adds sound at no extra cost and can edit or extend an existing video. 4K is available only on Seedance 2.0.
How does video editing work?
Upload a 4–15 second video, choose "Edit video" and describe the change (e.g. "make it night"). The result has the same length as the source. "Extend" continues the video instead.
What is Unlimited Seedance 2.5?
It turns on automatically with the Business plan: Seedance 2.5 videos (480p, 5s) are generated from a queue without spending credits. The fair-use terms are listed on the pricing page.
