# Introduction

> Swap any person in any video for a character.

StirVid is an AI video app that swaps any person in any video for a character. Upload a source video, pick a character, and get a video where that character performs the original motion, framing, and timing.

## How it works, in one paragraph

You bring a source video and choose a character from the public, platform-ready catalog. StirVid extracts a driving signal from your video, runs it through our motion engine, and returns a downloadable video where the character performs the original motion. Still images go through the image editor.

## Credits

StirVid uses a virtual currency called **CREDITS**, managed by our billing system. Every generation is priced server-side and deducted from your balance atomically. You cannot spend credits you do not have, and refunds happen automatically on job failure.
