What is Seedance?

Seedance is ByteDance's AI video model family, and the one most other apps quietly run on. The current flagship, Seedance 2.5, generates clips of up to 30 seconds in a single pass — no stitching shorter segments together — with dialogue, sound effects and music generated alongside the picture, at up to 1080p (a 4K variant followed for film and TV work). It accepts text, image and reference-video inputs, and it is the default video engine inside ByteDance's own Dreamina and CapCut apps.

There is no consumer Seedance subscription: developers buy it as an API through BytePlus ModelArk, billed per million tokens, which works out at roughly $0.10 a second at 480p, $0.23 at 720p and $0.57 at 1080p. Failed or moderated renders are not billed. Everyone else meets Seedance inside Dreamina, CapCut or a third-party platform, at that platform's own credit prices — so the same clip can cost very different amounts depending on where you run it.

Who Seedance Is Best For

Best for: Video creators, editors, and marketing teams get the most from Seedance — among the longest single-pass clips of any major model; native sound removes a whole post-production step.

Not ideal for: It may not suit you if any of these are dealbreakers: no standalone app or subscription — access is via API or other apps; per-token pricing takes maths to predict.
