It is a video codec with Discrete Cosine Transformation( DCT) as it is also used in H.261, H. 263, H. 264/ AVC, MPEG-2 and MPEG-4.

VC-1, which is also used in HDTV and features good compression ratios, can be used equally for HDTV displays in interlace at 1,920 x 1,080pixels, referred to as 1,080i, and for progressive scan displays at 1,280 x 720 pixels, referred to as 720p. VC-1 was adopted as an open standard by the Society of Motion Picture and Television Engineers( SMPTE) in 2006.

In addition to the standard version, there are two other versions with different profiles, WMVA and WVC1.
