Seedance 2.0

Seedance 2.0 is the latest AI video generation model developed by ByteDance's Seed research team. Building on the original Seedance, it delivers major improvements in motion coherence, physical realism, and multimodal generation capability.
Key Features
• Text-to-Video: Turn a single sentence into a complete cinematic scene with coherent motion
• Image-to-Video: Use reference images to guide composition, identity, and visual style
• Integrated Audio Generation: The Pro version generates synchronized video and audio in a single pass, including sound effects, background music, speech synthesis, and multilingual lip-sync
Technical Architecture
Seedance 2.0 uses a novel diffusion transformer architecture designed for temporal consistency between video frames. Unlike models that treat each frame independently, Seedance 2.0's temporal attention mechanism:
• Reuses motion cues across frames
• Preserves character identity and proportions
• Maintains consistent lighting and geometry
• Produces fewer flickers and smoother transitions
Physics-Aware Motion
Seedance 2.0 excels at understanding physical dynamics:
• Cloth fluttering in the wind
• Water splash physics
• Realistic flames and smoke
• Complex particle effects
