ByteDance's audio-video series — cinematic multi-shot clips from the 2.0 flagship to fast 1.0 tiers.
Seedance 2.0 generates coherent multi-shot sequences with stereo audio jointly — ByteDance's flagship capability, per its official launch.
ByteDance pitches 1.5 Pro on millisecond-level lip sync across multiple languages, with environmental sound and music in the same generation.
1.0 Fast is officially ~3x faster than 1.0 Pro at a fraction of the price — iterate there, then re-run the winning prompt on 2.0.

Commercial advertising is ByteDance's own headline use case — multi-shot sequences with sound, generated as one piece.
Officially pitched for explainers: narration-friendly pacing and shots that hold a subject steady.
ByteDance demos lean on complex motion — pair figure skating, wuxia choreography — where multi-subject interaction matters.
Multilingual speech with lip sync makes 1.5 Pro the tier for dialogue shots and character delivery.
Seedance is ByteDance's video generation series, built by its Seed team. The 2.0 generation uses a unified multimodal architecture that generates multi-shot video and audio jointly — stereo sound, stable motion and complex multi-subject interaction in one pass. Earlier tiers stay on the roster because they draft faster and cost less; Vormly runs six variants side by side so you can match cost to the shot.
Naming note: our 1.0 Quality and 1.0 Fast tiers run ByteDance's official seedance-1.0-pro and seedance-1.0-pro-fast models.
