# Permute's Workshop

Permute’s Workshop is a great way for Permute to offer less frequently used tools. Permute’s intention is to be a Swiss army knife of conversions, allowing you to get anything done. Permute’s Workshop allows Permute to be extended beyond simple conversions. By default, the workshop modules are not enabled by default, but one can easily enable them up in preferences.

Here is a quick overview of workshop modules currently bundled with Permute:

- Apply PDF Filter - this allows you to apply various filters to PDF files, including file size reduction. These filters are part of macOS and can be edited or added via the ColorSync Utility that’s part of macOS.
- IP Camera H.264 Fix-Up - some IP cameras produce a `.264` video files that are not playable anywhere, or the playback is not easily achievable. Permute can fix these files for you.
- MP4 Web Optimization - some MP4 files can have the `moov` atom located at the end of the file. This is fine for local playback, but is less optimal for embedding these videos on a webpage as the video needs to fully load before it can be played. This workshop module moves the atom to the front of the file, allowing playback while still loading. Note that Permute’s presets that produce MP4 files already produce files with `moov` atoms at the beginning of the file.
- Track Export - allows you to export individual tracks of the video.
