Text To Video V6 Max
The client provides a convenient way to interact with the model API.
npm install --save @fal-ai/clientSet 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("pixverse/v6/max/text-to-video", {
input: {
prompt: "Epic low-cut camera capture of a girl clad in ultraviolet threads, Peter Max art style depiction, luminous diamond skin glistening under a vast moon's radiance, embodied in a superhuman flight among mystical ruins, symbolizing a deity's ritual ascent, hyper-detailed"
},
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"
});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("pixverse/v6/max/text-to-video", {
input: {
prompt: "Epic low-cut camera capture of a girl clad in ultraviolet threads, Peter Max art style depiction, luminous diamond skin glistening under a vast moon's radiance, embodied in a superhuman flight among mystical ruins, symbolizing a deity's ritual ascent, hyper-detailed"
},
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("pixverse/v6/max/text-to-video", {
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("pixverse/v6/max/text-to-video", {
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);Read more about file handling in our file upload guide.
prompt string* requiredText prompt for the video generation. Limited to 2048 UTF-8 encoded bytes. Because the limit counts bytes rather than characters, emoji and non-Latin or accented characters (which use multiple bytes each) can push a visually short prompt over the cap.
aspect_ratio AspectRatioEnumThe aspect ratio of the generated video Default value: "16:9"
Possible enum values: 16:9, 4:3, 1:1, 3:4, 9:16, 2:3, 3:2, 21:9
resolution ResolutionEnumThe resolution of the generated video Default value: "720p"
Possible enum values: 360p, 540p, 720p, 1080p
duration integerThe duration of the generated video in seconds. v6 supports values from 1 to 15 seconds Default value: 5
negative_prompt stringNegative prompt to be used for the generation. Limited to 2048 UTF-8 encoded bytes. Because the limit counts bytes rather than characters, emoji and non-Latin or accented characters (which use multiple bytes each) can push a visually short prompt over the cap. Default value: ""
style EnumThe style of the generated video
Possible enum values: anime, 3d_animation, clay, comic, cyberpunk
seed integerThe same seed and the same prompt given to the same version of the model will output the same video every time.
generate_audio_switch booleanEnable audio generation (BGM, SFX, dialogue)
generate_multi_clip_switch booleanEnable multi-clip generation with dynamic camera changes
thinking_type EnumPrompt optimization mode: 'enabled' to optimize, 'disabled' to turn off, 'auto' for model decision
Possible enum values: enabled, disabled, auto
enable_safety_checker booleanAuthorized callers may set false to request relaxed screening. Default value: true
