Each compression specification defines various mechanisms by which raw video (in essence, a sequence of full-resolution uncompressed digital images) can be reduced in size, from simple bit compression (like Lempel-Ziv-Welch) to psycho-visual and motion summarization, and how the output is stored as a bit stream. So long as the encoder component ...
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 ]
Some containers only support a restricted set of video formats: DMF only supports MPEG-4 Visual ASP with DivX profiles. EVO only supports MPEG-4 AVC, MPEG-1 Video, MPEG-2 Video and VC-1. F4V only supports MPEG-4 AVC, MPEG-4 Visual and H.263. FLV only supports MPEG-4 Visual, VP6, Sorenson Spark and Screen Video. MPEG-4 AVC in FLV is possible ...

HEVC has a larger performance improvement for higher resolution images than lower resolution images and a larger performance improvement for lower bit rates than higher bit rates. For lossy compression to get the same PSNR as HEVC took on average 1.4× more bits with JPEG 2000, 1.6× more bits with JPEG-XR, and 2.3× more bits with JPEG. [170]
It's time to up your audio game. Apple Music and Spotify both announced they will offer lossless audio streaming. Apple will offer it in June, and Spotify will offer it...well, we're not sure yet ...
AppleFSCompression.framework (AFSC), the mechanism for quasi-transparent compression in HFS Plus and Apple File System, supports LZFSE and LZVN since OS X 10.9.. Apple's Disk Images framework has offered an LZFSE-based encoding called ULFO since Mac OS X 10.11, [9] accessible via hdiutil(1) [10] and some third-party image utilities.
