Create stunning AI videos with synchronized audio from text and images using Seedance 1.5 Pro by ByteDance
Sound and Vision, All in One Take
Seedance 1.5 Pro is the first AI video model to natively generate audio and video together — not as separate processes stitched in post, but as a unified generation. Every clip comes with synchronized dialogue, spatial sound effects, and ambient audio that perfectly matches the visuals on screen.
Cinematic Camera Control
Seedance 1.5 Pro understands cinematic language. Describe dolly zooms, tracking shots, crane movements, or continuous long takes and the model executes them with professional-grade precision. Combine that with advanced lighting instructions and compositional terms for truly film-quality results.
Multilingual Lip-Sync and Voice
Characters in your videos can speak naturally with precise lip-sync across multiple languages and regional dialects — including English, Mandarin, Japanese, Korean, Spanish, and even Sichuan and Shaanxi dialects. The voice quality is expressive and natural, far from the robotic output of earlier models.
10x Faster Than Previous Generation
Thanks to an optimized multi-stage distillation framework, Seedance 1.5 Pro delivers over 10x faster inference than its predecessor. Typical response times range from 45 seconds to 3 minutes depending on complexity and resolution — fast enough for rapid iteration and high-volume content production workflows.
