Seedance 2.5

Seedance 2.5 is ByteDance's next‑generation AI video model that generates a single native 30‑second clip in 4K resolution, eliminating the need for stitching multiple short segments. The model accepts up to 50 multimodal reference assets—text, images, video, and audio—so users can guide generation with detailed visual and auditory cues. It supports a wide range of file formats and allows combinations such as text + image + video + audio. Key upgrades over the earlier Seedance 2.0 include native 4K output, longer continuous clips, a larger reference budget, stronger character and scene consistency, and local area editing that lets users adjust specific parts of a clip without regenerating the whole video. Seedance 2.5 is aimed at social media creators, marketing and advertising teams, ecommerce sellers, and agencies that need production‑ready videos with consistent branding and the ability to iterate quickly.
