MPG video file is a variant of the MPEG (Moving Picture Experts Group) MPEG-1 or MPEG-2 video and audio compression format, optimized for broadcast quality video. MPEG-1 The most common implementations of the MPEG-1 standard provide a video resolution of 352-by-240 at 30 frames

per second (fps). This produces video quality slightly below the quality of conventional VCR videos.MPEG-2 Offers resolutions of 720?480 and 1280?720 at 60 fps, with full CD-quality audio. This is sufficient for all the major TV standards, including NTSC, and even HDTV. MPEG-2 is used by

DVD-ROMs. MPEG-2 can compress a 2 hour video into a few gigabytes. While decompressing an MPEG-2 data stream requires only modest computing power, encoding video in MPEG-2 format requires significantly more processing power.
