inference.partner.seedance-2-5.img2vid.v2

View markdown

The inference.partner.seedance-2-5.img2vid.v2 job animates an input image into a video guided by a text prompt using Dreamina Seedance 2.5.

{
"type": "inference.partner.seedance-2-5.img2vid.v2",
"config": {
"image": "reference.png",
"prompt": "a red fox trotting through a snowy forest at golden hour"
}
}

Supports resolution, aspect ratio, duration (or automatic duration with -1), seed (-1 or 0–2147483647), watermark, audio generation, and returning the last frame. See the job schema for model-specific limits and defaults.

Inputs are a first frame, or first and last frames. Use aspect_ratio: "adaptive". Multimodal references use the separate inference.partner.seedance-2-5.ref2vid.v2 type.

Set duration to -1 for automatic duration. Automatic duration is determined from the prompt and reference content.
