QuickLook Video
Thumbnails in Finder, Quick Look previews, and metadata in Spotlight
QuickLook Video is a free, open-source macOS utility that expands Finder's ability to preview audio and video files. It generates thumbnails and Quick Look previews for media formats not fully supported by macOS. Compatible containers include MKV, WebM, AVI, WMV, Ogg, FLV, and MXF. It also supports video codecs such as AV1, VP9, HEVC, VVC, and Theora. Spotlight integration makes additional media metadata available for searching and inspection. File information can also appear in Finder's Get Info window. The application uses Spotlight and Media Extensions to extend native macOS media handling. QuickLook Video helps users inspect diverse media collections without opening a separate player.
