![]() ![]() A more recent 64-bit version was released with WM Encoder 9 圆4 and IS VC-1 compliant (although not much different than the original). ![]() The first version that was released with WMP10 in fall 2004 was not VC-1 compliant (the VC-1 draft was only being submitted to SMPTE at the time). WMVA is the FourCC code of Microsoft's Windows Media Video Advanced Profile codec. It's compatible with both Windows Media Format SDK and DirectShow, but so far it hasn't really caught on outside of Microsoft. Because of its maturity, AVI still enjoys the widest support, so many people still prefer VCM codec interfaces.ĭMO is DirectX Media Object, the latest Microsoft format for codecs and transform filters. A lot of apps, such as VirtualDub, can only use VfW/VCM/ACM for compression and AVI as container. VCM is the Video Compression Manager, an old Video for Windows (dates to early 1990s) interface for video codecs. Whats a VCM? Whats a WMVA? Could someone explain all these terms? :)Īnyways, I dont understand half of these terms. The fact that I can act here as a liaison to the MS codec group - that's just an added perk of my job. I'm here primarily because I've been a Doom9 forum member for many years, even before I joined MS. Sorry if I don't always make that clear, but I'd hate for people to think that I'm here as an official spokesperson or something (or even worse, that I'm here to push a corporate agenda). I am a software test engineer in the video codec group. Hey Zambelli do you work for Microsoft or something? Because you live in Seattle, and your avatar is Windows Media. ![]()
