Interaction Modes

Seedance 2.0 supports two entry modes: Start & End Frame Reference and All-Round Reference. Intelligent multi-frame reference and subject reference functions are currently unavailable.

If you only upload a start frame image and a text prompt, please use the Start & End Frame Reference mode.
For multimodal combined input (images, videos, audio, and text), please enter the All-Round Reference mode.

The current interaction method is to specify the usage of each image, video, and audio file via @Material Name.

Example: @Image 1 as the start frame, @Video 1 for shot language reference, and @Audio 1 for background music.
