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 '.
The compressed audio and video are multiplexed into a QuickTime file. To reduce data rate and hardware requirements, video frame has size of 960 horizontal by 540 vertical pixels with pixel aspect ratio of 1:1, which results in 16:9 display aspect ratio.
CBR is commonly used for videoconferences, satellite and cable broadcasting. VBR is commonly used for video CD/DVD creation and video in programs. Bit rate control is suited to video streaming. For offline storage and viewing, it is typically preferable to encode at constant quality (usually defined by quantization) rather than using bit rate ...
Apple Video is a lossy video compression and decompression algorithm developed by Apple Inc. and first released as part of QuickTime 1.0 in 1991. [1] The codec is also known as QuickTime Video , by its FourCC RPZA and the name Road Pizza .
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 ...
Users can choose between various lossless direct audio/video transfers between container formats or lossy video/audio encoding, with encoding possessing the added ability to change video and audio specifications such as bitrate, frame rate, audio channels, resolution, sampling rate, and aspect ratio. SUPER is also able to utilize its back-end's ...
The H.264 video format has a very broad application range that covers all forms of digital compressed video from low bit-rate Internet streaming applications to HDTV broadcast and Digital Cinema applications with nearly lossless coding. With the use of H.264, bit rate savings of 50% or more compared to MPEG-2 Part 2 are reported.
QuickTime 4 was the first version to support streaming. It was accompanied by the release of the free QuickTime Streaming Server version 1.0. QuickTime 4 Player introduced brushed metal to the Macintosh user interface. On December 17, 1999, Apple provided QuickTime 4.1, this version's first major update. [46]
