Text-to-Video

Changed on

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)

  1. Upload your inputs (video, image, or audio) with Generate Upload URLs and copy the file_path.
  2. Send a request to create a text to video job with the basic fields.
  3. Check the job status until it's complete, then download the result from downloads.

Key options

  • Inputs: usually a file, sometimes a YouTube link, depending on project type
  • Resolution: output size and plan requirements vary by workflow and model. Some workflows derive output size from the input video.
  • Extra fields: e.g. face_swap_mode, start_seconds/end_seconds, or a text prompt

Cost
Credits are charged when the job is queued (credits_charged in the response). Tools billed per frame charge an estimate and settle to the frames that actually render once the job finishes; tools billed per second charge the final amount upfront. Failed jobs are refunded.

For detailed examples, see the product page.

Response

Success

idstring required

Unique ID of the video. Use it with the Get video Project API to fetch status and downloads.

The amount of credits deducted from your account to generate the video. If the status is not 'complete', this value is an estimate and may be adjusted upon completion based on the actual FPS of the output video.

If video generation fails, credits will be refunded, and this field will be updated to include the refund.
