LTX 2.3 Reframe
LTX · Video · Video → Video
Reframe a video into a new aspect ratio — the source is re-cropped and the newly exposed edges are generated to match. Takes no prompt.
ltx-v2.3-reframeWorkflow: ltx-2.3/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.green-salad-4efd.toolsminati.workers.dev',
});
// Calls the 'ltx-2.3/reframe' workflow directly — params are sent as-is.
const { result, usage } = await ai.apis.run('ltx-2.3/reframe', {
video_url: "https://storage.googleapis.com/falserverless/example_outputs/ltxv-2-t2v-output.mp4"
}, {
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.green-salad-4efd.toolsminati.workers.dev',
});
// mode: ASYNC submits the job and polls under the hood — you just await.
const { result } = await ai.apis.run('ltx-2.3/reframe', {
video_url: "https://storage.googleapis.com/falserverless/example_outputs/ltxv-2-t2v-output.mp4"
}, {
mode: ApiRunMode.ASYNC,
});
console.log(result);Parameters
4 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 |
|---|---|---|---|---|
resolutionThe target output resolution tier. Combined with the aspect ratio to determine the output size. | string | no | 1080p | 720p1080p |
aspect_ratioThe target aspect ratio to reframe the video to. | string | no | 16:9 | 1:14:55:49:1616:9 |
video_urlThe URL of the video to reframe. Must be publicly accessible or a base64 data URI. The video is re-cropped to the target aspect ratio and the newly exposed areas are filled with generated content that matches the original. Max duration 60 seconds. | string | yes | — | e.g. https://storage.googleapis.com/falserverless/example_outputs/ltxv-2-t2v-output.mp4 |
optionsPlatform-specific options for safety checks and Picsart Drive integration. | object | no | — | — |
└ safety_checksSafety check configuration. | object | no | — | — |
└ enabledEnable or disable text safety checks. Defaults to true. | boolean | no | true | — |
└ drivePicsart Drive storage options. When provided, the result will be saved to the user's Drive. | object | no | — | — |
└ nameFilename to save the result as in Picsart Drive. | string | yes | — | — |
└ attributesAdditional file metadata attributes. | object | no | — | — |
└ folderDestination 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.
