# Licenses & Credits

VidStudio runs entirely in your browser and relies on open-source software. This page credits the projects we use and the licenses they are made available under.

## FFmpeg

VidStudio invokes [FFmpeg](https://ffmpeg.org/) — a free multimedia framework — to handle certain video and audio processing operations. FFmpeg is licensed under the GNU General Public License v2 (or later).

The FFmpeg WebAssembly binary is **not** hosted or redistributed by VidStudio. Your browser fetches it directly from the public npm mirror at [cdn.jsdelivr.net](https://cdn.jsdelivr.net/npm/@ffmpeg/core-mt@0.12.9/) the first time you use a feature that requires it.

FFmpeg source code is available from [ffmpegwasm/ffmpeg.wasm](https://github.com/ffmpegwasm/ffmpeg.wasm) (the WebAssembly port) and [git.ffmpeg.org/ffmpeg.git](https://git.ffmpeg.org/ffmpeg.git) (upstream FFmpeg). The full text of the GPL v2 license is available at [gnu.org/licenses/gpl-2.0](https://www.gnu.org/licenses/old-licenses/gpl-2.0.html).
