Seedance 2 is a multi-modal AI video generator that accepts up to four input types—images (up to 9), videos (up to 3), audio files (up to 3), and text prompts—combined into a single generation (up to 12 files). Users assign roles to assets with @ references (e.g., @image1 as first frame, @video1 for camera movement). The model produces 4–15 second cinematic clips with built-in sound, lip-sync, beat synchronization, visual consistency, camera replication, video editing and smooth one-take continuity for commercial and creative projects.
