QuickLook Video

Thumbnails in Finder, Quick Look previews, and metadata in Finder's Get Info window 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 ISO file formats. 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 which performed a similar function with the QuickTime framework before QuickTime was replaced by AVFoundation).
