QuickTime

QuickTime is an extensible proprietary multimedia framework developed by Apple Inc., capable of handling various formats of digital video, picture, sound, panoramic images, and interactivity. The classic version of QuickTime is available for Windows XP and later, as well as Mac OS X Leopard and later operating systems. A more recent version, QuickTime X (10.0) is currently available on Mac OS X Snow Leopard and Mac OS X Lion.

It is available free of charge for both Mac OS X and Windows operating systems. There are some other free player applications that rely on the QuickTime framework, providing features not available in the basic QuickTime Player. For example, iTunes can export audio in WAV, AIFF, MP3, AAC, and Apple Lossless. In addition, Mac OS X has a simple AppleScript which can be used to play a movie in full-screen mode., but since version 7.2 full-screen viewing is now supported in the non-pro version.

QuickTime Player 7 is limited to only basic playback operations unless a QuickTime Pro license key is purchased from Apple. Apple's professional applications (e.g. Final Cut Pro, Logic Studio) include a QuickTime Pro license. Pro keys are specific to the major version of QuickTime for which they are purchased and unlock additional features of the QuickTime Player application on Mac OS X or Windows. Also, the Pro key does not entail any additional downloads.

AVI

Audio Video Interleave (also Audio Video Interleaved), known by its acronym AVI, is a multimedia container format introduced by Microsoft in November 1992 as part of its Video for Windows technology. AVI files can contain both audio and video data in a file container that allows synchronous audio-with-video playback.

Like the DVD video format, AVI files support multiple streaming audio and video, although these features are seldom used. Most AVI files also use the file format extensions developed by the Matrox OpenDML group in February 1996. These files are supported by Microsoft, and are unofficially called "AVI 2.0".

MPEG-1

MPEG-1 is a standard for lossy compression of video and audio. 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-2

MPEG-2 is a standard for "the generic coding of moving pictures and associated audio information". It describes a combination of lossy video compression and lossy audio data compression methods which permit storage and transmission of movies using currently available storage media and transmission bandwidth.

The Video section, part 2 of MPEG-2, is similar to the previous MPEG-1 standard, but also provides support for interlaced video, the format used by analog broadcast TV systems. MPEG-2 video is not optimized for low bit-rates, especially less than 1 Mbit/s at standard definition resolutions. All standards-compliant MPEG-2 Video decoders are fully capable of playing back MPEG-1 Video streams conforming to the Constrained Parameters Bitstream syntax. MPEG-2/Video is formally known as ISO/IEC 13818-2 and as ITU-T Rec. H.262.
