}AI Video Editor
What this API does
Create the same Video Editor 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 video editor 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 video editor 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.
