Seedance 2.5

ByteDance's longest single take: up to 30 seconds with sound, guided by images, clips and audio you upload.

What is Seedance 2.5?

Seedance 2.5 is ByteDance's video model for long single shots, with sound made in the same pass as the picture.

It generates 4 to 30 seconds in one continuous take at 480p, 720p or 1080p. On Nsketch you can steer it with up to 30 reference images, 3 reference videos and 10 audio clips, or pin the opening and closing frames instead.

Length is the reason to pick it. Most video models stop around 8 to 15 seconds, so a longer scene means generating pieces and cutting them together, with jumps in faces and lighting at every cut. Seedance 2.5 plans the whole take at once, so a character stays the same person from the first second to the last.

Prompts to try with Seedance 2.5

“A single continuous shot of a matte black perfume bottle on wet basalt. The camera starts on one water droplet, slowly orbits the bottle as silver dust rises into a glass halo around it, then pulls back to a dark studio. Soft rain and a low synth hum. 12 seconds, 9:16.”

Good to know before you generate

  • Credits are per second: 15 a second at 480p, 34 at 720p and 85 at 1080p. A 4-second 480p clip costs 60.
  • Use either first and last frames or reference media in one generation, not both.
  • Reference videos add to the cost and switch the aspect ratio to match the reference.
  • Reference videos and audio clips are each capped at 30 seconds in total.
