Seeddance is a unified AI creative platform that combines multiple video, image and music models into a single multimodal workflow. Users can upload up to 12 assets (images, videos, audio, text), use a universal @ reference syntax to assign roles to each asset, and generate 4–15 second cinematic videos with built-in dual-channel stereo audio, lip-sync, camera replication, visual consistency across frames, and editing/extension features. It includes a credit-based pricing model, daily free credits, and plans for creators and teams.
