iFrame is a digital video format developed by Apple. 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 ...
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 '.
Apple ProRes is a high quality, "visually lossless" lossy video compression format developed by Apple Inc. for use in post-production that supports video resolution up to 8K.It is the successor of the Apple Intermediate Codec and was introduced in 2007 with Final Cut Studio 2. [1]
The quality the codec can achieve is heavily based on the compression format the codec uses. A codec is not a format, and there may be multiple codecs that implement the same compression specification – for example, MPEG-1 codecs typically do not achieve quality/size ratio comparable to codecs that implement the more modern H.264 specification.
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 ...
This display link runs independently from the application which invokes video playback, and it compensates for different display refresh rates and latency. [2] Because QuickTime 7 employed Core Video, it was the first version of QuickTime to implement the rendering capability of Quartz. Previous versions of QuickTime used QuickDraw for ...
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]
