X-Pert Quality Check is a quality control tool, intended to guarantee the successful playout of media files in X-Pert Playout. X-Pert Quality Check checks directories, playlists or sets of files. Content verifications include loudness measurement and/or detection of missing audio/video samples. X-Pert Quality Check stores quality data about each checked media file to an *.mtd file.  X-Pert Playout can play or skip a clip depending on that quality data and the user settings.
