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 3 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.
