Seedance 2.5

by ByteDance

Seedance 2.5 generates up to 30 seconds of video in one pass, roughly double the native length of Seedance 2.0, with sound effects, ambience and lip-synced speech rendered in the same pass. One model id covers text-to-video, image-to-video (with an optional last frame) and reference-to-video. Reference mode takes images, video clips and audio cited in the prompt as @Image1, @Video1 and @Audio1, and can also edit or extend a supplied clip. Output is 480p, 720p or 1080p across 16:9, 9:16, 21:9, 4:3, 3:4 and 1:1.
