Hevc codec download windows 8.15/26/2023 ![]() ![]() ![]() 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 to 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. ![]()
