  "formatDescription": "MPEG-2 is a lossy compression standard (an improvement and expansion of the MPEG-1 standard) designed for the generic coding of video and audio and intended to cover a wide scope of application, including: video production, broadcast and editing. Streams are at potentially higher bitrates than MPEG-1 but more efficient compression making it suited to High Definition video. MPEG-2 Video supports both 'progressive' and 'interlaced' frame video. An MPG2 \u2018Elementary\u2019 stream (ES) file (*.m2v) contains either a single video or audio stream. ES files are generally intended for video editing or other intermediate use, where separate audio content can be ultimately blended ('interleaved' or \u2018muxed\u2019) with a video stream to produce an output file containing both audio and video for synchronised playback.",
