Seedance 2.0 is a cloud-based AI video generation platform that transforms text prompts or images into coherent multi-shot 2K videos with native audio. Using a Dual-Branch Diffusion Transformer, it jointly generates video and audio in one pass—delivering synchronized dialogue, Foley, and ambient sound with phoneme-level lip-sync across multiple languages. The engine automates scene transitions, maintains persistent characters, supports image-to-video motion synthesis, and is optimized for speed and commercial use with credit-based plans and RESTful API access.
