# Generate videos from templates with one API call.

Animate a design once in the browser editor. Send it data and get back an MP4, WebM or GIF, with music and voice-over mixed into the soundtrack.

## How it works

1. ### Animate the template
   Add keyframes, text animation and scene transitions in the editor, or start from an animated gallery template. Mark the parts that change as variables.
2. ### Call the render endpoint
   Send format mp4, webm or gif with your values, at up to 60 frames a second. Or send up to 500 rows in one bulk request and get one video per row.
3. ### Get the video
   You get a hosted link back. The video runs for the template's scenes added together, with its audio layers mixed into one track.
