Seedance 2.5: 30 seconds, real control

ByteDance Seed’s Seedance 2.5 is out: one-pass clips up to 30 seconds, with room to extend across more rounds when you need a longer cut.1

In the same pass you can stack up to 30 images, 10 video clips, and 10 audio clips as references — enough to lock faces, motion, and sound together instead of hoping one still carries the whole scene. Timestamp-level edits, green-screen swaps, camera-path rewrites, and clay / reference-based editing are the control layer that actually changes the workflow.1

It’s live in Jimeng AI and Doubao Pro video generation. If you’re building multi-shot work, start with a clay block-in for camera and blocking, then dress materials from stills — that’s the move 2.5 is built to reward.1
