What Seedance does
Seedance is ByteDance's flagship AI video generation model, built by the team behind TikTok and CapCut. Seedance 2.0, released in February 2026, accepts text, images, video, and audio as inputs (up to 12 assets in a single generation) and produces cinematic, multi-shot video with native synchronized audio, consistent characters, and frame-level precision. It is one of the few video models that generates picture and sound together.
Key capabilities
Seedance 2.0 outputs high-quality 1080p video and offers two modes: a Standard mode tuned for maximum quality and a Fast mode for quick iterations. It supports clips up to roughly 20 seconds with realistic physics and strong prompt adherence, and can automatically create dialogue, ambient soundscapes, and sound effects matched to the visuals frame by frame. Outside China, the model is accessible through ByteDance's Dreamina platform and via third-party APIs such as fal and AtlasCloud.
Who it's for
Seedance targets creators, marketers, filmmakers, and developers who need short cinematic video with synchronized audio for social content, advertising, previsualization, and product demos.
