About Seedance 2.5 - Image to Video
ByteDance Seedance 2.5 animates a starting frame from a text motion prompt, with optional end-frame control for transitions and synchronized audio on by default. Supports 480p, 720p, and 1080p output (1080p uses 10-bit color and H.265/HEVC encoding) and durations from 4 to 30 seconds. The output keeps the aspect ratio of the first-frame image.
