Motion Transfer Endpoint
1. Calling the API#
Install the client#
The client provides a convenient way to interact with the model API.
npm install --save @fal-ai/client
Migrate to @fal-ai/client
The @fal-ai/serverless-client
package has been deprecated in favor of @fal-ai/client
. Please check the migration guide for more information.
Setup your API Key#
Set FAL_KEY
as an environment variable in your runtime.
export FAL_KEY="YOUR_API_KEY"
Submit a request#
The client API handles the API submit protocol. It will handle the request status updates and return the result when the request is completed.
import { fal } from "@fal-ai/client";
const result = await fal.subscribe("moonvalley/marey/motion-transfer", {
input: {
prompt: "Detailed Description: A fast, smooth dolly shot glides forward at water level through a monumental, minimalist colonnade. The imposing, symmetrical rows of brutalist marble columns rush past on either side, their strong vertical lines creating a sense of powerful, constant motion. The dark, glassy water of a central pool perfectly reflects the towering structures, with gentle ripples disturbing the mirror image as the camera advances. The scene is cinematic and moody, with the light-colored stone contrasting against the dark water and the pale sky visible at the far end of the architectural tunnel. shot on 35mm, film, organic, analog, motion blur
Background: A pale, overcast sky and a distant treeline are framed by the opening at the end of the colonnade, growing larger as the camera moves forward.
Middleground: The two rows of massive, geometric columns recede into the distance, their uniform shapes creating a hypnotic, rhythmic pattern that rushes past the lens.
Foreground: The camera skims just above the surface of the dark, rippling water, which reflects the blurred motion of the columns passing on the left and right.",
video_url: "https://d1kaxrqq3vfrw5.cloudfront.net/fal-launch-assets/guide-assets/fal-motion-transfer-input-5s.mp4"
},
logs: true,
onQueueUpdate: (update) => {
if (update.status === "IN_PROGRESS") {
update.logs.map((log) => log.message).forEach(console.log);
}
},
});
console.log(result.data);
console.log(result.requestId);
2. Authentication#
The API uses an API Key for authentication. It is recommended you set the FAL_KEY
environment variable in your runtime when possible.
API Key#
import { fal } from "@fal-ai/client";
fal.config({
credentials: "YOUR_FAL_KEY"
});
Protect your API Key
When running code on the client-side (e.g. in a browser, mobile app or GUI applications), make sure to not expose your FAL_KEY
. Instead, use a server-side proxy to make requests to the API. For more information, check out our server-side integration guide.
3. Queue#
Submit a request#
The client API provides a convenient way to submit requests to the model.
import { fal } from "@fal-ai/client";
const { request_id } = await fal.queue.submit("moonvalley/marey/motion-transfer", {
input: {
prompt: "Detailed Description: A fast, smooth dolly shot glides forward at water level through a monumental, minimalist colonnade. The imposing, symmetrical rows of brutalist marble columns rush past on either side, their strong vertical lines creating a sense of powerful, constant motion.

},
webhookUrl: "https://optional.webhook.url/for/results",
});
Fetch request status#
You can fetch the status of a request to check if it is completed or still in progress.
import { fal } from "@fal-ai/client";
const status = await fal.queue.status("moonvalley/marey/motion-transfer", {
requestId: "764cabcf-b745-4b3e-ae38-1200304cf45b",
logs: true,
});
Get the result#
Once the request is completed, you can fetch the result. See the Output Schema for the expected result format.
import { fal } from "@fal-ai/client";
const result = await fal.queue.result("moonvalley/marey/motion-transfer", {
requestId: "764cabcf-b745-4b3e-ae38-1200304cf45b"
});
console.log(result.data);
console.log(result.requestId);
4. Files#
Some attributes in the API accept file URLs as input. Whenever that's the case you can pass your own URL or a Base64 data URI.
Data URI (base64)#
You can pass a Base64 data URI as a file input. The API will handle the file decoding for you. Keep in mind that for large files, this alternative although convenient can impact the request performance.
Hosted files (URL)#
You can also pass your own URLs as long as they are publicly accessible. Be aware that some hosts might block cross-site requests, rate-limit, or consider the request as a bot.
Uploading files#
We provide a convenient file storage that allows you to upload files and use them in your requests. You can upload files using the client API and use the returned URL in your requests.
import { fal } from "@fal-ai/client";
const file = new File(["Hello, World!"], "hello.txt", { type: "text/plain" });
const url = await fal.storage.upload(file);
Auto uploads
The client will auto-upload the file for you if you pass a binary object (e.g. File
, Data
).
Read more about file handling in our file upload guide.
