Production teams needing 30-second AI clips with audio; mainly in ByteDance's Chinese apps so far, with no stated price.

Kenning's take

What it does

Seedance 2.5 generates up to 30 seconds of video with matching audio in a single pass, which can be extended twice. It reads reference videos more closely, edits more reliably, and adds tools such as green-screen editing for production work. Press reports it launched on 31 July 2026 in ByteDance's own apps, with BytePlus API access after.

  • Up to 30-second clips, extendable twice
  • Joint audio and video
  • Reference video understanding
  • Green-screen and white-model control

Who it suits. Video creators and production teams who need longer AI clips.
