ByteDance's audio-visual generation model with a 4.5B-parameter Dual-Branch Diffusion Transformer architecture. Seedance 1.5 Pro generates video and audio together in one pass, which avoids the timing issues of sequential dubbing. It supports multi-language lip-sync (English, Mandarin, Japanese, Korean, Spanish, and more), cinematic camera control (pan, tilt, zoom, orbit), multi-character dialogue, and character consistency across shots. It produces clips of 4–12 seconds at up to 1080p.
