About Seedance 2.5 - Text to Video
ByteDance Seedance 2.5 generates video from a text prompt, with synchronized audio on by default. Supports 480p, 720p, 1080p, and 4k output (1080p and 4k use 10-bit color and H.265/HEVC encoding), durations from 4 to 30 seconds, and multiple aspect ratios.
Draft mode renders a quick 480p preview for checking the scene, motion, and prompt. Its draft task ID then renders the final video at 1080p or 4k with the same prompt, media, and settings, and stays valid for seven days after the draft is created.
