A macOS app that adds Finder thumbnails, Quick Look previews, and Get Info metadata support for a wide range of audio and video file formats not natively handled by macOS. It works via a Spotlight extension and Media Extensions that extend AVFoundation with support for additional codecs and containers.
Use cases
- preview mkv and webm files in Quick Look on Mac
- show video thumbnails in Finder for avi and flv files
- get metadata for audio files like wma and ogg in Finder Get Info
- add HEVC and VP9 codec support to macOS Quick Look
- play and preview non-native media formats on macOS
When to choose
- you need Finder previews or thumbnails for media formats macOS doesn't support natively
- you want a maintained, App Store-distributed replacement for Perian-style codec support
When to avoid
- you only work with natively supported formats like MP4/H.264
- you need full playback of exotic codecs rather than previews and thumbnails
