bytedance/seedance-2.5
Seedance 2.5 generates a single-shot video of up to 30 seconds from a text prompt, with synchronised audio.
Model Inputs
The text prompt used to generate the video
Video resolution - 480p for faster generation, 720p for balance, 1080p for high quality.
Duration of the video in seconds. Supports 4 to 30 seconds, or auto to let the model decide based on the prompt.
The aspect ratio of the generated video. Use 16:9 for landscape, 9:16 for portrait/vertical, 1:1 for square, 21:9 for ultrawide cinematic, or auto to let the model decide.
Whether to generate synchronized audio for the video, including sound effects, ambient sounds, and lip-synced speech. The cost of video generation is the same regardless of whether audio is generated or not.
Output bitrate mode. 'high' requests a higher-quality, larger-file encode from the model; 'standard' uses the default bitrate.

Readme
Seedance 2.5 produces native single-shot video up to 30 seconds long at 480p, 720p or 1080p, from a text prompt alone.
Synchronised audio - sound effects, ambience and lip-synced speech - is generated by default and costs nothing extra. Set duration to auto to let the model pick a length that suits the prompt, and bitrate_mode to high for a larger, higher-quality encode.
