Seedance 2

Seedance 2 is ByteDance's flagship text-to-video generation model, distributed through hosted APIs and positioned by integrators as the company's most advanced video system. It accepts a broad range of conditioning inputs, including text prompts, still images, audio clips, and existing video, which lets creators guide motion, style, and sound design from a single request. The architecture is described as producing cinematic output with native audio, real-world physics, and director-level camera control, indicating a unified multimodal design that handles motion and sound jointly rather than treating audio as a separate post-processing stage. Reference-to-video endpoints further let users anchor outputs to example clips for character, scene, or stylistic consistency across generations.

Practically, Seedance 2 fits workflows that need high-fidelity short-form video with synchronized sound, such as advertising spots, music-driven social content, and previsualization for film and game production. Integrators expose it through several endpoints, including optimized "fast" variants, so teams can trade latency for fidelity depending on whether they are iterating on a storyboard or rendering a final cut. Native 4K generation is highlighted as a headline feature, giving creators room to crop, stabilize, or re-frame footage without visible quality loss. Because the model combines text, image, audio, and video conditioning in one pipeline, it is well suited to projects where a single reference asset, whether a mood board, a voice sample, or a brief clip, should shape the entire output.
