Reframe a video to a new aspect ratio using Luma Ray 3.2 (early access).
luma-ray-3.2-reframe-videoWorkflow: luma-ray32-video-reframeOverview
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).
import { createClient, ApiRunMode } from '@picsart/ai-sdk';
const ai = createClient({
apiKey: process.env.PICSART_API_KEY,
apiUrl: 'https://api.picsart.com',
});
// Calls the 'luma-ray32-video-reframe' workflow directly — params are sent as-is.
const { result, usage } = await ai.apis.run('luma-ray32-video-reframe', {
prompt: "A serene mountain lake at golden hour, ultra detailed",
aspect_ratio: "9:16",
source: {}
}, {
mode: ApiRunMode.SYNC,
});
console.log(result); // workflow-specific output
console.log(usage?.credits); // credits chargedAsync (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.
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('luma-ray32-video-reframe', {
prompt: "A serene mountain lake at golden hour, ultra detailed",
aspect_ratio: "9:16",
source: {}
}, {
mode: ApiRunMode.ASYNC,
});
console.log(result);Parameters
6 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.
| Parameter | Type | Required | Default | Details |
|---|---|---|---|---|
promptDescribes the content to paint into the new canvas area (1-6000 characters) | string | yes | — | — |
aspect_ratioTarget aspect ratio (must differ from the source). | string | yes | — | 9:163:41:14:316:921:9 |
sourceSource video: generation_id, or url/data with video/* media_type (≤30s). | object | yes | — | — |
└ generation_idChain reference to a prior completed video generation owned by the same client | string | no | — | — |
└ urlPartner-hosted video URL. Requires media_type (video/*). Source must be ≤ 30s. | string | no | — | — |
└ dataInline base64 video. Requires media_type (video/*). Source must be ≤ 30s. | string | no | — | — |
└ media_typeVideo MIME type when url/data is used (e.g. "video/mp4") | string | no | — | — |
user_idStable opaque end-user identifier (no PII), ≤256 chars. | string | no | — | — |
videoVideo output + reframe options. Standard dynamic range only — HDR/EXR, loop, edit, and anchor frames are not applicable to reframe. | object | no | — | — |
└ resolutionOutput resolution. | string | no | — | 540p720p1080p |
└ source_positionNormalized rect controlling where the source sits in the new canvas. Omit for centered-fit. | object | no | — | — |
└ x_normLeft edge of source rect, fraction of canvas width [-2.0, 2.0] | number | yes | — | — |
└ y_normTop edge of source rect, fraction of canvas height [-2.0, 2.0] | number | yes | — | — |
└ w_normSource rect width, fraction of canvas width (0, 2.0] | number | yes | — | — |
└ h_normSource rect height, fraction of canvas height (0, 2.0] | number | yes | — | — |
optionsGenAI options (safety checks, Picsart Drive) | object | no | — | — |
└ safety_checksSafety check settings | object | no | — | — |
└ enabledWhether to run content moderation. Defaults to true. | boolean | no | — | — |
└ driveSave result to Picsart Drive | object | no | — | — |
└ nameFile name in Picsart Drive | string | yes | — | — |
└ attributesCustom attributes to attach to the file | object | no | — | — |
└ folderTarget folder in Picsart Drive | object | no | — | — |
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 resultitself is the vendor's own shape.
