SMPTE 421, [2] informally known as VC-1, is a video coding format. Most of it was initially developed as Microsoft's proprietary video format Windows Media Video 9 in 2003. With some enhancements including the development of a new Advanced Profile, it was officially approved as an SMPTE standard on April 3, 2006.

H.264 and VC-1 are popular video compression standards gaining use in the industry as of 2007.
