About
QuickLook Video provides thumbnails in Finder, Quick Look previews, and metadata and previews in Finder's Get Info window for most types of audio and video files. QuickLook, AVFoundation, and Spotlight natively understand only a limited number of media files, mostly MPEG audio and video codecs within ISO file formats.
The app adds support for a wide range of other codecs and non-native file types. These include formats such as Matroska (.mkv), WebM, Windows Media (.wmv), AVI, QuickTime (.mov), Flash Video (.flv), and MXF. Supported video codecs include VP9, AV1, HEVC/H.265, VVC/H.266, Theora, and Cinepak, and supported audio codecs include Vorbis, Windows Media Audio, and WavPack.
The app contains a Spotlight extension that adds support for non-native file formats, along with two Media Extensions that add support to AVFoundation for non-native formats and video codecs. Long-time Mac users may remember Perian, which performed a similar function before QuickTime was replaced by AVFoundation.
