MiniMax H3 Max Relight

VIDEOFeaturedminimax-h3-max-relight

MiniMax H3 Max Relight from MiniMax lights an existing clip again from a light setup: place each light around the subject and set its colour and brightness, and the footage is re-rendered under that light while its subjects, motion, camera, and soundtrack stay as they were. Provide a source clip of up to 15 seconds; the output runs the same length at 480p, 768p, 1080p, or 2K. Built for matching shots to a scene’s time of day, adding mood to game trailers, and trying lighting looks on a cutscene without re-rendering it.

Parameters

Path Parameters

workspace_id

required

Workspace Id

Id of the workspace that owns the resource.

string format: uuid

Id of the workspace that owns the resource.

Query Parameters

session_name

Session Name

Organize this run under a named session. A new session is created if none matches.

string

nullable

Organize this run under a named session. A new session is created if none matches.

Header Parameters

Idempotency-Key

string

<= 255 characters

Opaque key making this request safe to retry. The first request with a given key executes; a later request with the same key returns that first response with Idempotent-Replayed: true instead of executing again. The key covers the method, path, query, and body it was first used with; reusing it for a different request is rejected with 422. Replayable for 24 hours.
