Longer takes, wider frames with Seedance 2.5

ByteDance Seed's newest video model — up to 30 seconds a clip, 21:9 through 9:16.

Seedance 2.5 is the current generation of ByteDance Seed's video model, and it is the widest-ranging video option in the LazyKiwi workbench. Where Seedance 2.0 caps aspect ratio at 1:1 and steps duration in fixed jumps, 2.5 opens every second from 4s to 30s and adds cinematic 21:9 and 4:3 / 3:4 framing. It accepts a text prompt, a single reference image, or a start and end frame pair, takes prompts up to 5,000 characters, and reads up to nine reference images in one run. Specs: up to 480p or 720p.
