SMPTE 4. 21. M, informally known as VC 1, is a video coding format. It was initially developed as the proprietary video format Windows Media Video 9 by Microsoft in 2. SMPTE video codec standard on April 3, 2. It is today a supported standard found in Blu ray Discs, Microsofts Silverlight framework, and the now discontinued HD DVD. VC 1 is an evolution of the conventional DCT based video codec design also found in H. MPEG 1 Part 2, H. MPEG 2 Part 2, H. MPEG 4 Part 2. It is widely characterized as an alternative to the ITU T and MPEG video codec standard known as H. MPEG 4 AVC. VC 1 contains coding tools for interlaced video sequences as well as progressive encoding. The main goal of VC 1 Advanced Profile development and standardization was to support the compression of interlaced content without first converting it to progressive, making it more attractive to broadcast and video industry professionals. Both HD DVD and Blu ray Disc have adopted VC 1 as a video standard, meaning their video playback devices will be capable of decoding and playing video content compressed using VC 1. Windows Vista partially supports HD DVD playback by including the VC 1 decoder and some related components needed for playback of VC 1 encoded HD DVD movies. Microsoft has designated VC 1 as the Xbox 3. VC 1 for full motion video included with games. By means of an October 3. Windows Media Video could be played on the Xbox 3.

Station 3 console and the FFmpeg project includes a VC 1 decoder. On August 2. Raspberry Pi Foundation announced hardware decoding support for VC 1. Microsoft codec implementationseditThe VC 1 codec specification has so far been implemented by Microsoft in the form of 3 codecs, each identified with a unique four character code. Simple and Main Profiles of VC 1 remained completely faithful to the existing WMV3 implementation, making WMV3 bitstreams fully VC 1 compliant. The WMV3 codec was designed to primarily support progressive encoding for computer displays. An interlaced encoding mode was implemented, but quickly became deprecated when Microsoft started implementing WMV Advanced Profile. Aiseesoft_HD_Converter_for_Mac_695150.jpg' alt='Apple Prores 422 Codec For Adobe Media Encoder' title='Apple Prores 422 Codec For Adobe Media Encoder' />Whereas WMV3 progressive encoding was implemented in the YUV 4 2 0 color space, the deprecated interlaced mode was implemented in the less common YUV 4 1 1 color space. The Windows Media Video 9 WMV3 codec implements the Simple and Main modes of the VC 1 codec standard, providing high quality video for streaming and downloading. It provides support for a wide range of bit rates, from high definition content at one half to one third the bit rate of MPEG 2, to low bit rate Internet video delivered over a dial up modem. This codec also supports professional quality downloadable video with two pass and variable bit rate VBR encoding. A number of high definition movies and videos have been released commercially in a format dubbed WMV HD. These titles are encoded with WMV3 Main Profile High Level MPHL. WMVA was the original implementation of WMV Advanced Profile prior to the acceptance of the VC 1 draft by SMPTE. The codec was distributed with Windows Media Player 1. Windows Media Format SDK 9. There are slight bitstream differences between WMVA and WVC1, so consequently WMVA is handled by a different Direct. Show decoder than WVC1. Some 3rd party hardware and software decoders only decode WMVA based content. As of 2. 00. 6, WMVA is considered a deprecated codec because it is not fully VC 1 compliant. WVC1, also known as Windows Media Video 9 Advanced Profile, implements a more recent and fully compliant Advanced Profile of the VC 1 codec standard. It offers support for interlaced content and is transport independent. With the previous version of the Windows Media Video 9 Series codec, users could deliver progressive content at data rates as low as one third that of the MPEG 2 codec and still get equivalent or comparable quality to MPEG 2citation needed. The Windows Media Video 9 Advanced Profile codec also offers this same improvement in encoding efficiency with interlaced contentscitation needed. A decoder for WVC1 is included in Windows Media Player 1. Windows Vista and is available as a download for Windows XP. This implementation is supported in Microsoft Silverlight. ProfileseditSimple.

Other implementationseditDue to its origins in Microsofts WMV9 codec, the most popular implementations of VC 1 encoders have so far been done by Microsoft, though third party implementations exist as well. Sonic Cinevision PSE, a professional VC 1 encoding tool used predominantly in HD DVD and Blu ray encoding, is a commercial version of Microsofts PEP Parallel Encoder encoding tool and VC 1 Analyzer tool. Microsoft owns the code development whereas Sonic Solutions owns the sales and distribution. Microsoft also provides a separate VC 1 Encoder SDK which allows any company or software developer to integrate VC 1 encoding into their applications. Non Microsoft VC 1 implementations based entirely on the SMPTE specifications have been done by Tandberg Television and Main. Concept. 6 The FFmpeg project includes a free VC 1 decoder. Encoding softwareeditWindows Media Encoder 9 Series encodes VC 1 compliant video files, including WVC1 Four. CC media. Windows Media Format 1. Runtime or Windows Media Player 1. VC 1 compliance across all three profiles Simple, Main and Advanced. If either of these are installed, Windows Movie Maker can also save VC 1 compliant videos, as can any other application built on the Windows Media Format SDK or Windows Media Codec DMOs. A Windows Media Encoder Studio Edition was initially announced for professional encoding but later cancelled by Microsoft. Microsoft Expression Encoder which is part of Expression Studio supports encoding VC 1 video to the Windows Media ASF file format and the IIS Smooth Streaming format. Video encoder products made by Inlet, Digital Rapids, Harmonic, Envivio, Elemental Technologies, Anystream, Telestream and Rhozet support VC 1 encoding based on the Microsoft VC 1 Encoder SDK for IPTV and Web streaming.
