Seedance

Seedance is ByteDance’s multimodal AI video model that generates cinematic, multi-shot narrative sequences with synchronized stereo audio.

Developed by the team behind TikTok and CapCut, Seedance 2.0 moves beyond single-clip generation to produce cohesive, edited scenes up to 15 seconds long. The model employs a quad-modal input system (text, image, audio, and video) that allows creators to lock in specific character faces, motion styles, and soundscapes through an all-around reference architecture. By integrating dual-channel stereo technology, it ensures that sound effects like the strike of a match or the rustle of fabric are perfectly synced with the visual frame. This technology effectively shifts the AI workflow from asset generation to digital directing, providing professional-grade 1080p output with physical accuracy that rivals traditional production.
