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 ...
Integrated Multi Format Codec (MFC) provides encoding and decoding of MPEG-4/H.263/H.264 up to 1080p@30fps and decoding of MPEG-2/VC1/MPEG-4 video up to 1080p@30fps. Alma Technologies provides ultra low latency H.264 Encoder IP cores since 2011 capable of encoding Full HD video even on low cost FPGA devices. Standalone hardware implementations ...
A The maximum bit rate of the profile is based on the combination of bit depth, chroma sampling, and the type of profile. [3] For bit depth the maximum bit rate increases by 1.5x for 12-bit profiles and 2x for 16-bit profiles. [3] For chroma sampling the maximum bit rate increases by 1.5x for 4:2:2 profiles and 2x for 4:4:4 profiles. [3]
There is also FAAC, the same project's encoder, but it is proprietary (but still free of charge). libgsm – Lossy compression ; opencore-amr – Lossy compression (AMR and AMR-WB) liba52 – a free ATSC A/52 stream decoder (AC-3) libdca – a free DTS Coherent Acoustics decoder; Codec2 – Low bitrate compression, primarily voice
Dirac's implementers made a preliminary claim of "a two-fold reduction in bit rate over MPEG-2 for high definition video", which makes it comparable to VC-1 and simpler profiles of H.264. [11] Dirac supports both constant bit rate and variable bit rate operation. When the low delay syntax is used, the bit rate will be constant for each area ...
^ f As of July 2008, about 66.7% of Blu-ray discs are region free and 33.3% use region codes. [ 6 ] ^ g DVD supports any valid MPEG-2 refresh rate as long as it is packaged with metadata converting it to 576i50 or 480i60, This metadata takes the form of REPEAT_FIRST_FIELD instructions embedded in the MPEG-2 stream itself, and is a part of the ...

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.
