ByteDance · Seedance 2.5
Seedance 2.5
One take, thirty seconds, fully directed.
What it is
Seedance 2.5 is ByteDance's follow-up to Seedance 2.0. It generates a 30-second audio-video clip in a single pass, then extends it in rounds that keep characters, scenes and pacing consistent across several minutes.
Its reference set is the widest in this catalogue: up to 30 images, 10 video clips and 10 audio clips in one request, including clay renders for blocking and camera paths. Timestamp-level editing then lets you fix one moment without regenerating the whole take.
Profiles describe the model, not a guarantee: the Skill folder is what makes the work repeatable, and the agent's settings decide what the model can reach.
What it's best at
The work this engine is built for, and where it earns its place in a run.
One-take storytelling
Thirty seconds organized as setup, development, turn and resolution, with multi-round extension beyond that.
Fifty references
Clay renders for blocking, motion and camera references, plus up to ten audio clips — all in one request.
Timestamp editing
Direct or edit a specific second, with green-screen, camera-perspective and reference-based editing.
Native audio
Dialogue, music and effects generated in sync with the picture.
A good first run
Three video Skills to try on Seedance 2.5 — each one a folder of instructions the model can pick up straight away.
Other models
