Key Features of Seedance 2.0 Video AI API
Dual-Branch Architecture for Coherent Output
The API is built on ByteDance's Dual-Branch Diffusion Transformer architecture, which processes video and audio in a single, parallel pass. This results in highly synchronized and coherent multimodal video generation without the need for complex post-processing.
Native Audio Synchronization
Unlike many competitors that require separate audio workflows, the Seedance 2.0 Video AI API generates sound directly alongside the video. This built-in sound generation delivers polished, production-ready clips, saving significant time and effort.
Flexible Resolution and Duration

Multiple Aspect Ratio Support
To cover all platform requirements, the API supports six different aspect ratios. These include 21:9 ultrawide, 16:9 landscape, 9:16 vertical, 1:1 square, 4:3 standard, and 3:4 portrait, ensuring videos are optimized for any social media or display format.
Optional Fixed Camera Mode
For scenarios requiring stable shots, such as product demos or talking-head videos, the API provides an optional fixed camera mode. This feature locks the camera position, allowing for controlled and professional scene generation.
Strong Prompt Adherence
The underlying Seedance 2.0 model is designed to accurately interpret and visualize complex text prompts. It effectively handles detailed descriptions of objects, actions, scene dynamics, and even cinematography terminology for precise creative control.
