The Windows Media Video 9 Advanced Profile codec also offers this same improvement in encoding efficiency with interlaced contents.

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-2. It offers support for interlaced content and is transport independent. 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. As of 2006, WMVA is considered a deprecated codec because it is not fully VC-1 compliant.

Some 3rd party hardware and software decoders only decode WMVA based content. There are slight bitstream differences between WMVA and WVC1, so consequently WMVA is handled by a different DirectShow decoder than WVC1.

The codec was distributed with Windows Media Player 10 and Windows Media Format SDK 9.5 install packages. WMVA was the original implementation of WMV Advanced Profile prior to the acceptance of the VC-1 draft by SMPTE. These titles are encoded with WMV3 Main Profile High Level ( ). This codec also supports professional-quality downloadable video with two-pass and variable bit rate (VBR) encoding." Ī number of high definition movies and videos have been released commercially in a format dubbed WMV HD. "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. 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. Whereas WMV3 progressive encoding was implemented using the YUV 4:2:0 color sampling scheme, the deprecated interlaced mode was implemented using the less common YUV 4:1:1 sampling scheme. An interlaced encoding mode was implemented, but quickly became deprecated when Microsoft started implementing WMV Advanced Profile. The WMV3 codec was designed to primarily support progressive encoding for computer displays. The Simple and Main Profiles of VC-1 remained completely faithful to the existing WMV3 implementation, making WMV3 bitstreams fully VC-1 compliant. The VC-1 codec specification has so far been implemented by Microsoft in the form of three codecs, each identified with a unique four character code. On August 24, 2012, the Raspberry Pi Foundation announced hardware decoding support for VC-1. VC-1 is supported in the PlayStation 3 console and the FFmpeg project also includes a VC-1 decoder.

By means of an Octoupdate, all formats of Windows Media Video could be played on the Xbox 360 from a disc, USB storage device, or streaming from a PC via Windows Media Connect/Windows Media Player 11.

Microsoft designated VC-1 as the Xbox 360 video game console's official video format, and game developers could use VC-1 for full motion video included with games. 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. The main goal of the development and standardization of the VC-1 Advanced Profile was to support interlace-optimized compression of interlaced content without first converting it to progressive scan, making it more attractive to broadcast and video industry professionals using the 1080i format.īoth HD DVD and Blu-ray Disc adopted VC-1 as a supported video format, meaning their video playback devices are required be capable of decoding and playing video-content compressed using VC-1. The Advanced Profile of VC-1 contains tools designed for coding interlaced video sequences as well as progressive scan video. It was widely characterized as an alternative to the ITU-T and MPEG video codec standard known as H.264/MPEG-4 AVC. VC-1 is an evolution of the conventional block-based motion-compensated hybrid video coding design also found in H.261, MPEG-1 Part 2, H.262/MPEG-2 Part 2, H.263, and MPEG-4 Part 2. VC-1 is supported in the now-deprecated Microsoft Silverlight, the briefly-offered HD DVD disc format, and the Blu-ray Disc format. After its development, several companies other than Microsoft asserted that they held patents that applied to the technology, including Panasonic, LG Electronics and Samsung Electronics. It was primarily marketed as a lower-complexity competitor to the H.264/MPEG-4 AVC standard. With some enhancements including the development of a new Advanced Profile, it was officially approved as a SMPTE standard on April 3, 2006. Most of it was initially developed as Microsoft's proprietary video format Windows Media Video 9 in 2003. SMPTE 421, informally known as VC-1, is a video coding format.
