Seedance 3 is AI video generation software that creates cinematic videos using multimodal inputs like images, videos, audio files, and text prompts within a unified workspace. Images define character appearance or product details, videos demonstrate movement patterns, and audio files guide sound direction, reducing ambiguity in the process. The software generates single videos up to 30 seconds, allowing complete scene planning in one sequence. Projects can include up to 50 reference materials, such as 30 images, 10 videos, and 10 audio files, with native 4K output ensuring visual clarity for textures and close-ups. Seedance 3 uses reference-led direction, enabling creators to specify camera paths, lighting, and styles by pointing to materials rather than relying solely on text. It features 3D spatial pre-visualization and camera blocking tools for scene planning. Videos are watermark-free, and the software operates on a credit-based system via subscriptions or one-time purchases.
