About QuickLook Video
QuickLook Video adds Finder thumbnails, Quick Look previews, and metadata in Finder's Get Info window for most types of audio and video files. macOS natively understands only a limited number of media files, mostly MPEG codecs within ISO file formats.
This app extends that support to a wide range of other formats and codecs, including Matroska, WebM, AVI, Windows Media, and Flash Video files, and codecs such as VP9, AV1, HEVC, and Theora. It works through a Spotlight extension and two Media Extensions that add non-native file formats and video codecs to AVFoundation.
