QuickTime Animation format (also known as QuickTime RLE) is a video compression format and codec created by Apple Computer to enable playback of RGB video in real time without expensive hardware. [ 1 ] [ 2 ] It is generally found in the QuickTime container with the FourCC 'rle '.
It is based on existing industry standards, such as AVC/H.264, AAC and QuickTime, and can be used with compatible Mac and PC applications. [1] The format has been created to simplify video editing. Many non-Apple editing tools do not require conversion of video from source to intermediate format, instead allowing to edit the original videos ...

QuickTime Alternative is a smaller package and lacks the full complement of software included in Apple QuickTime, including QuickTime Player, PictureViewer, and any QuickTime Pro features. In addition, QuickTime Alternative does not run background processes such as the optional QuickTime Tray Icon from the official distribution. [citation needed]
Variable frame rate (or VFR) is a term in video compression for a feature supported by some container formats which allows for the frame rate to change actively during video playback, or to drop the idea of frame rate completely and set an individual timecode for each frame.
M-JPEG is an intraframe-only compression scheme (compared with the more computationally intensive technique of interframe prediction).Whereas modern interframe video formats, such as MPEG1, MPEG2 and H.264/MPEG-4 AVC, achieve real-world compression ratios of 1:50 or better, M-JPEG's lack of interframe prediction limits its efficiency to 1:20 or lower, depending on the tolerance to spatial ...
QuickTime Graphics is a lossy video compression and decompression algorithm developed by Apple Inc. and first released as part of QuickTime 1.x in the early 1990s. [1] The codec is also known by the name Apple Graphics and its FourCC SMC. [2] [1] The codec operates on 8-bit palettized RGB data. [1]
In QuickTime Pro's MPEG-4 Export dialog, an option called "Passthrough" allows a clean export to MP4 without affecting the audio or video streams. One discrepancy ushered in by QuickTime 7 released on April 29, 2005, is that the QuickTime file format supports multichannel audio (used, for example, in the high-definition trailers on Apple's site ...
