Endpoint for generating a video from a video and an image.
The client provides a convenient way to interact with the model API.
npm install --save @fal-ai/clientThe @fal-ai/serverless-client package has been deprecated in favor of @fal-ai/client. Install the new package and update your imports — see client setup.
Set FAL_KEY as an environment variable in your runtime.
export FAL_KEY="YOUR_API_KEY"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("fal-ai/wan/v2.2-14b/animate/move", {
input: {
video_url: "https://v3b.fal.media/files/b/panda/a6SvJg96V8eoglMlYFShU_5385885-hd_1080_1920_25fps.mp4",
image_url: "https://v3b.fal.media/files/b/panda/-oMlZo9Yyj_Nzoza_tgds_GmLF86r5bOt50eMMKCszy_eacc949b3933443c9915a83c98fbe85e.png"
},
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);The API uses an API Key for authentication. It is recommended you set the FAL_KEY environment variable in your runtime when possible.
import { fal } from "@fal-ai/client";
fal.config({
credentials: "YOUR_FAL_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.
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("fal-ai/wan/v2.2-14b/animate/move", {
input: {
video_url: "https://v3b.fal.media/files/b/panda/a6SvJg96V8eoglMlYFShU_5385885-hd_1080_1920_25fps.mp4",
image_url: "https://v3b.fal.media/files/b/panda/-oMlZo9Yyj_Nzoza_tgds_GmLF86r5bOt50eMMKCszy_eacc949b3933443c9915a83c98fbe85e.png"
},
webhookUrl: "https://optional.webhook.url/for/results",
});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("fal-ai/wan/v2.2-14b/animate/move", {
requestId: "764cabcf-b745-4b3e-ae38-1200304cf45b",
logs: true,
});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("fal-ai/wan/v2.2-14b/animate/move", {
requestId: "764cabcf-b745-4b3e-ae38-1200304cf45b"
});
console.log(result.data);
console.log(result.requestId);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.
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.
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.
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);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.
video_url string* requiredURL of the input video.
image_url string* requiredURL of the input image. If the input image does not match the chosen aspect ratio, it is resized and center cropped.
guidance_scale floatClassifier-free guidance scale. Higher values give better adherence to the prompt but may decrease quality. Default value: 1
resolution ResolutionEnumResolution of the generated video (480p, 580p, or 720p). Default value: "480p"
Possible enum values: 480p, 580p, 720p
seed integerRandom seed for reproducibility. If None, a random seed is chosen.
num_inference_steps integerNumber of inference steps for sampling. Higher values give better quality but take longer. Default value: 20
enable_safety_checker booleanIf set to true, input data will be checked for safety before processing. Disabling it requires account authorization; unauthorized requests are always checked.
enable_output_safety_checker booleanIf set to true, output video will be checked for safety after generation.
shift floatShift value for the video. Must be between 1.0 and 10.0. Default value: 5
video_quality VideoQualityEnumThe quality of the output video. Higher quality means better visual quality but larger file size. Default value: "high"
Possible enum values: low, medium, high, maximum
video_write_mode VideoWriteModeEnumThe write mode of the output video. Faster write mode means faster results but larger file size, balanced write mode is a good compromise between speed and quality, and small write mode is the slowest but produces the smallest file size. Default value: "balanced"
Possible enum values: fast, balanced, small
return_frames_zip booleanIf true, also return a ZIP archive containing per-frame images generated on GPU (lossless).
use_turbo booleanIf true, applies quality enhancement for faster generation with improved quality. When enabled, parameters are automatically optimized for best results.
