QuickLook Video
===============
[](https://apps.apple.com/us/app/quicklook-video/id6759566961)
Finder Thumbnails, Quick Look previews, Get Info metadata and previews for most types of audio and
video files.
QuickLook, AVFoundation and Spotlight understand a limited number of media files - mostly only MPEG
audio and video codecs within MPEG container files. This app adds support for wide range of other
codecs and "non-native" media file types, including:
* File formats: Matroska `.mka`, `.mkv`, WebM `.webm`, Windows Media `.wma`, `.wmv`,
Ogg Video `.ogm`, `.ogv`, AVI `.avi`, QuickTime `.mov`, Flash Video `.flv`, `.f4v`,
Real Media `.ra`, `.rm`, `.rv`, SMPTE `.gxf`, `.mxf`.
* Audio codecs: Vorbis, Windows Media Audio, WavPak, ATRAC, etc.
* Video codecs: VP6, VP8, VP9, AV1, HEVC/H.265, VVC/H.266, Dolby Vision, Theora, DXV, HAP, Sorenson,
Cinepak, AIC, Flash, Real Video, DivX, Intel Indeo, QuickTime animation, etc.
How does it work?
-----------------
The app contains a Spotlight extension that adds support for non-native file formats, and two Media
Extensions that add support to AVFoundation for non-native file formats and video codecs.
(Long-time Mac users may remember [Perian](https://www.perian.org) which performed a similar
function with the QuickTime framework before QuickTime was replaced by AVFoundation).
