What is Seedance 1.5 Pro?
Seedance 1.5 Pro is ByteDance's breakthrough audio-visual AI video model, the first to generate synchronized video and audio in a single pass. Built on a 4.5-billion-parameter Dual-Branch Diffusion Transformer, it eliminates the disconnect between sight and sound that plagues traditional AI video tools. Dialogue matches lip movements at phoneme-level precision, sound effects arrive exactly when actions occur, and background music responds to the semantic content of your scene — all without post-production.
The model supports multilingual dialogue across 8+ languages including English, Mandarin, Japanese, Korean, Spanish, and Indonesian, with multi-person conversations maintaining distinct vocal identities. With resolution up to 1080p and cinematic camera controls — dolly zooms, tracking shots, crane movements — Seedance 1.5 Pro bridges the gap between AI experimentation and professional video production.
