MiniMax-H3 2K Regeneration

Regenerates a 768P video that matches the MiniMax-H3 output specification into 2K. This is not a general-purpose upscaler for arbitrary videos.

Method and Path

Source Video Passing Methods

When regenerating by source video URL, you must re-attach the original task’s prompt, images, reference video, and reference audio verbatim. Regeneration by task ID requires an upstream whitelist and the source task must still be within the 7-day query window.

Path Parameters

string
required
The gateway task ID of the source video, i.e. the id returned by the create endpoint. The gateway converts it to the upstream task ID automatically.

Body

string
required
Model name. Currently only MiniMax-H3 is supported.
string
Required when regenerating via metadata.base_video, and must exactly match the final prompt used to generate the 768P source video.
integer
Source video duration; should match the actual source duration.
string
The first-frame image of the original task. Required verbatim when using the base_video method and the original task was image-to-video.
array<string>
The image inputs of the original task. Must match the original request when using the base_video method.
string
768P source video URL. The source must contain an audio track, be 24 fps, have width and height both divisible by 32, an area ≤ 768×1344, and a total frame count of 107–362.
integer
Source video duration, provided by the caller when regenerating by source video URL.
string
The reference video used by the original task. Must match the original request when using the base_video method.
