The workflow performs the following action
- upload local assets to Magic Hour storage. So you can pass in a local path instead of having to upload files yourself
- trigger a generation
- poll for a completion status. This is configurable
- if success, download the output to local directory
Tip
This is the recommended way to use the SDK unless you have specific needs where it is necessary to split up the actions.
In addition to the parameters listed in the create section below, generate introduces 3 new parameters:
waitForCompletion(boolean, default true): Whether to wait for the project to complete.downloadOutputs(boolean, default true): Whether to download the generated filesdownloadDirectory(string, optional): Directory to save downloaded files (defaults to current directory)
import { Client } from "magic-hour";
const client = new Client({ token: process.env["API_TOKEN"]!! });
const res = await client.v1.textToVideo.generate(
{
endSeconds: 5.0,
name: "Text To Video video",
orientation: "landscape",
resolution: "720p",
style: { prompt: "a dog running" },
},
{
waitForCompletion: true,
downloadOutputs: true,
downloadDirectory: ".",
},
);What this API does
Create the same Text To Video you can make in the browser, but programmatically, so you can automate it, run it at scale, or connect it to your own app or workflow.
Good for
- Automation and batch processing
- Adding text to video into apps, pipelines, or tools
How it works (3 steps)
- Upload your inputs (video, image, or audio) with Generate Upload URLs and copy the
file_path. - Send a request to create a text to video job with the basic fields.
- Check the job status until it's
complete, then download the result fromdownloads.
Key options
- Inputs: usually a file, sometimes a YouTube link, depending on project type
- Resolution: free users are limited to 576px; higher plans unlock HD and larger sizes
- Extra fields: e.g.
face_swap_mode,start_seconds/end_seconds, or a text prompt
Cost
Credits are only charged for the frames that actually render. You'll see an estimate when the job is queued, and the final total after it's done.
For detailed examples, see the product page.

true |
model |
✗ | ✗ | The AI model to use for video generation. * default: uses our currently recommended model for general use. For paid tiers, defaults to kling-3.0. For free tiers, it defaults to ltx-2. * ltx-2: Fast iteration with audio and lip-sync * wan-2.2: Fast, strong visuals with effects * seedance: Fast iteration and start/end frames * seedance-2.0: State-of-the-art quality and consistency * kling-2.5: Motion, action, and camera control * kling-3.0: Cinematic, multi-scene storytelling * sora-2: Story-first concepts and creativity * veo3.1: Realistic visuals and prompt adherence * veo3.1-lite: Good for fast, affordable, high-quality daily generation. Legacy models: * kling-1.6: Reliable baseline with smooth motion If you specify the deprecated model value that includes the -audio suffix, this will be the same as included audio as true. |
