Seedance
ByteDance's AI video-generation model line, known for long, high-resolution clips with audio generated in sync.
Definition
Seedance is ByteDance's family of AI video-generation models, competing with systems like Sora and Veo. It turns a text prompt, image, or other reference material into a video clip, and its newer versions generate audio alongside the visuals in a shared process so that sound effects and on-screen action line up naturally, rather than adding sound as a separate step afterward. Later releases extended how long a single clip can run, raised output resolution, and increased the number of reference inputs, such as example images or style guides, a creator can feed in to steer a generation. ByteDance, which also owns TikTok, offers Seedance through its Jimeng and Doubao apps, with API access rolling out through its Volcano Engine cloud platform.
