Text-to-Video

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: 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.

  • default: uses our currently recommended model for general use. For paid tiers, defaults to kling-3.0. For free tiers, it defaults to ltx-2.3.
  • ltx-2.3: Fastest output. Best for rapid iteration.
  • wan-2.2: Strong physics, camera moves, and motion.
  • kling-3.0: Best overall quality for cinematic storytelling.
  • veo3.1-lite: Veo quality at a more accessible cost.
  • veo3.1: Google's model. Highest realism and detail.
  • seedance-1.5: Smooth, consistent motion with precision.
  • seedance-2.0-mini: Fast, consistent video with strong motion quality
  • seedance-2.0: Top quality with reference-to-video control.
  • sora-2: Open AI's model. Great for creativity and viral clips.

If you specify the deprecated model value that includes the -audio suffix, this will be the same as included audio as true.

idstring required

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

credits_chargedinteger required

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.
