Reframes a long video scene-by-scene.
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-vace-apps/long-reframe", {
input: {
video_url: "https://storage.googleapis.com/falserverless/web-examples/wan/t2v.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);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-vace-apps/long-reframe", {
input: {
video_url: "https://storage.googleapis.com/falserverless/web-examples/wan/t2v.mp4"
},
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-vace-apps/long-reframe", {
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-vace-apps/long-reframe", {
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.
prompt stringThe text prompt to guide video generation. Optional for reframing. Default value: ""
negative_prompt stringNegative prompt for video generation. Default value: "letterboxing, borders, black bars, bright colors, overexposed, static, blurred details, subtitles, style, artwork, painting, picture, still, overall gray, worst quality, low quality, JPEG compression residue, ugly, incomplete, extra fingers, poorly drawn hands, poorly drawn faces, deformed, disfigured, malformed limbs, fused fingers, still picture, cluttered background, three legs, many people in the background, walking backwards"
seed integerRandom seed for reproducibility. If None, a random seed is chosen.
resolution ResolutionEnumResolution of the generated video. Default value: "auto"
Possible enum values: auto, 240p, 360p, 480p, 580p, 720p
aspect_ratio AspectRatioEnumAspect ratio of the generated video. Default value: "auto"
Possible enum values: auto, 16:9, 1:1, 9:16
num_inference_steps integerNumber of inference steps for sampling. Higher values give better quality but take longer. Default value: 30
guidance_scale floatGuidance scale for classifier-free guidance. Higher values encourage the model to generate images closely related to the text prompt. Default value: 5
sampler SamplerEnumSampler to use for video generation. Default value: "unipc"
Possible enum values: unipc, dpm++, euler
shift floatShift parameter for video generation. Default value: 5
video_url string* requiredURL to the source video file. This video will be used as a reference for the reframe task.
enable_safety_checker booleanIf set to true, the safety checker will be enabled. Disabling it requires account authorization; unauthorized requests are always checked.
acceleration EnumAcceleration to use for inference. Options are 'none' or 'regular'. Accelerated inference will very slightly affect output, but will be significantly faster. Default value: regular
Possible enum values: none, low, regular
video_quality VideoQualityEnumThe quality of the generated video. Default value: "high"
Possible enum values: low, medium, high, maximum
video_write_mode VideoWriteModeEnumThe write mode of the generated video. Default value: "balanced"
Possible enum values: fast, balanced, small
enable_auto_downsample booleanWhether to enable auto downsample. Default value: true
auto_downsample_min_fps floatMinimum FPS for auto downsample. Default value: 6
interpolator_model InterpolatorModelEnumThe model to use for frame interpolation. Options are 'rife' or 'film'. Default value: "film"
Possible enum values: rife, film
sync_mode booleanIf True, the media will be returned as a data URI and the output data won't be available in the request history.
transparency_mode TransparencyModeEnumThe transparency mode to apply to the first and last frames. This controls how the transparent areas of the first and last frames are filled. Default value: "content_aware"
Possible enum values: content_aware, white, black
return_frames_zip booleanIf true, also return a ZIP file containing all generated frames.
zoom_factor floatZoom factor for the video. When this value is greater than 0, the video will be zoomed in by this factor (in relation to the canvas size,) cutting off the edges of the video. A value of 0 means no zoom.
trim_borders booleanWhether to trim borders from the video. Default value: true
scene_threshold floatThreshold for scene detection sensitivity (0-100). Lower values detect more scenes. Default value: 30
paste_back booleanWhether to paste back the reframed scene to the original video. Default value: true
