Seedance 2.5: 30-Second AI Video From One Photo
Five to ten seconds is where most engines hit their wall, and everything past it becomes editing work: stitched takes, faces that drift between cuts, sound that refuses to line up. Seedance 2.5 \u2014 ByteDance\u2019s long-form bet in the Dreamina family \u2014 removes the wall instead of working around it: one still grows into a single native 30-second take with audio locked to the picture. What follows: capabilities, pricing on this site, where the budget tier fits, and the free way in.
What Seedance 2.5 does
- 4–30 second single-pass clips — the longest of any model on our lineup (Vidu Q4: 16s, Kling: 10s, Veo: 8s)
- Synchronized native audio — dialogue and effects locked to motion, no extra charge
- 480p / 720p / 1080p on the same model
- Coherent long takes — characters, lighting and sound stay consistent because it's one generation, not glued clips
