Seedance 2.0 is ByteDance's next-generation AI video generator that produces cinema-grade video with synchronized audio in a single model. Released in February 2026, it adopts a unified multimodal audio-video joint generation architecture, supporting text, image, audio, and video inputs for the most comprehensive content creation capabilities in the industry. For the first time, a single AI model generates video with native audio, including phoneme-perfect lip-sync in 8+ languages, multi-shot storytelling with natural cuts and transitions, and physics-based sound effects. Seedance 2.0 generates videos up to 15 seconds at resolutions from 480p to 2K at 24fps, supporting up to 12-file multimodal input. Creators can control performance, lighting, shadow, and camera movement with full precision. The model features World ID character consistency, maintaining perfect consistency for faces, clothing, text, scenes, and visual styles across entire videos. Available through ByteDance's Dreamina platform with free daily credits, Seedance 2.0 also offers API access for developers and integration through third-party platforms.
