![]() ![]() It also exploits temporal and spatial redundancy common in video to achieve better data compression than would be possible otherwise. ![]() It reduces or completely discards information in certain frequencies and areas of the picture that the human eye has limited ability to fully perceive. These are all very good suggestions on how to play mpeg2 files, but since I love QT, and am basically trying to pimp my Quicktime as much as possible, I would like a plug-in for QT, which. MPEG-1 Video exploits perceptual compression methods to significantly reduce the data rate required by a video stream. ![]() Each track either contains a digitally-encoded media stream (using a specific format) or a data reference to the media stream located in another file. The format specifies a multimedia container file that contains one or more tracks, each of which stores a particular type of data: audio, video, or text (e.g. It is designed to compress VHS-quality raw digital video and CD audio down to 1.5 Mbit/s (26:1 and 6:1 compression ratios respectively) without excessive quality loss, making video CDs, digital cable/satellite TV and digital audio broadcasting (DAB) possible. MPEG-1 is a standard for lossy compression of video and audio. Because both the QuickTime and MP4 container formats can use the same MPEG-4 formats, they are mostly interchangeable in a QuickTime-only environment. The International Organization for Standardization approved the QuickTime file format as the basis of the MPEG-4 file format. QuickTime File Format (QTFF) is a computer file format used natively by the QuickTime framework. Motion Picture Experts Group File Interchange Format
