MiniMaxMiniMax H3 Max RelightVideo → Video

Relight an existing video with MiniMax H3 Max — a sphere-render reference image sets the target lighting and the output keeps the source clip's length. Sources up to 15s, output up to 2K.

Overview

Alongside the unified model APIs, we expose compatibility APIs that take each vendor's original parameters exactly as the vendor defines them — nothing renamed, nothing reshaped on the way through.

That makes them the shortest path onto Picsart if you already work with the vendor directly: the request bodies you've already written keep working as they are. You keep their parameter names and defaults, and you get the vendor's full parameter set rather than the subset that is shared across every model.

The cost is that a request is written for one vendor — switching models later means rewriting it, and results come back in the vendor's own shape. When you'd rather write once and change models freely, use the unified API.

Make a request

Call the workflow with ai.apis.run() in TypeScript, or hit /workflows/{workflow}/execute directly — params is passed through untouched either way.

These endpoints are addressed by workflow name rather than model id: the one in this model's header, since one model runs as one workflow. Authentication is unchanged — your Picsart API key as a bearer token (see Authentication).

ts
import { createClient, ApiRunMode } from '@picsart/ai-sdk';

const ai = createClient({
  apiKey: process.env.PICSART_API_KEY,
  apiUrl: 'https://api.picsart.com',
});

// Calls the 'minimax/h3-max/relight' workflow directly — params are sent as-is.
const { result, usage } = await ai.apis.run('minimax/h3-max/relight', {
  video_url: "https://cdn.example.com/input.mp4",
  reference_image_url: "https://cdn.example.com/input.jpg"
}, {
  mode: ApiRunMode.SYNC,
});

console.log(result); // workflow-specific output
console.log(usage?.credits); // amount charged, in $

Async (submit & poll)

This model can run longer than the sync limit (~20s). In TypeScript, ai.apis.run(…, { mode: ApiRunMode.ASYNC }) polls for you; over HTTP, submit and poll yourself.

ts
import { createClient, ApiRunMode } from '@picsart/ai-sdk';

const ai = createClient({
  apiKey: process.env.PICSART_API_KEY,
  apiUrl: 'https://api.picsart.com',
});

// mode: ASYNC submits the job and polls under the hood — you just await.
const { result } = await ai.apis.run('minimax/h3-max/relight', {
  video_url: "https://cdn.example.com/input.mp4",
  reference_image_url: "https://cdn.example.com/input.jpg"
}, {
  mode: ApiRunMode.ASYNC,
});

console.log(result);

Parameters

8 parameters, sent inside params. These are the vendor's own names, so they line up one-for-one with the vendor's documentation. Required ones must be supplied; the rest fall back to their defaults.

ParameterTypeRequiredDefaultDetails
resolution
Output video resolution. 480P and 768P generate natively; 1080P and 2K (1440p) use latent upscaling and refinement from 768P.
stringno768P
480P768P1080P2K
seed
Random seed for video generation.
integerno——
sync_mode
Return video as a data URI.
booleannofalse—
enable_safety_checker
Enable safety checking.
booleannotrue—
video_url
Source video up to 15 seconds long. Converted to constant 24 fps and trimmed at the end to the closest 17n+5 frame count, with at least 56 frames (about 2.33 seconds) remaining. The output matches this prepared video's frame count and duration.
stringyes—
min 1 chars
aspect_ratio
Output video aspect ratio.
stringno16:9
adaptive21:916:94:31:13:49:16
reference_image_url
Sphere render showing the target lighting.
stringyes—
min 1 chars
options
Platform-specific options for safety checks and Picsart Drive integration.
objectno——
└safety_checks
Safety check configuration.
objectno——
└enabled
Enable or disable text safety checks. Defaults to true.
booleannotrue—
└drive
Picsart Drive storage options. When provided, the result will be saved to the user's Drive.
objectno——
└name
Filename to save the result as in Picsart Drive.
stringyes——
└attributes
Additional file metadata attributes.
objectno——
└folder
Destination folder in Picsart Drive.

Response

Over HTTP the output arrives inside a status envelope, at response.result. ai.apis.run() unwraps that envelope for you and resolves to { result, usage } instead. Either way the result itself is the vendor's own shape.
