The inference.seedance-2.txt2vid.v1 job generates a video from a text prompt using Dreamina Seedance 2.0.

{
    "type": "inference.seedance-2.txt2vid.v1",
    "config": {
        "prompt": "a red fox trotting through a snowy forest at golden hour"
    }
}

Additional configuration:

  • resolution (string; one of 480p, 720p, 1080p; default 1080p)
  • aspect_ratio (string; one of 16:9, 4:3, 1:1, 3:4, 9:16, 21:9, adaptive; default adaptive)
  • duration (integer; default 5)
  • watermark (boolean; default False)
  • camera_fixed (boolean; default False)
  • generate_audio (boolean; default True)
  • return_last_frame (boolean; default False)
  • seed (integer)

This job type is also available under its partner alias inference.partner.seedance-2.txt2vid.v1.
