Seedance 2.0 Fast is a multimodal AI video generation platform that converts prompts and references into short cinematic clips. Users can upload up to 12 mixed reference files (images, videos, audio) and use an @ syntax to assign roles for characters, motion and rhythm. The engine supports text-to-video, image-to-video, motion transfer from reference videos, native audio synthesis with precise lip-sync, automatic storyboarding (AI agent mode), and physics-aware motion for realistic interactions. It produces consistent multi-shot narratives at 1080p in seconds and offers subscription and credit-based pricing for production workflows.
