The MainConcept VC-1 Codec Package offers fast encoding and decoding speeds in the Simple, Main as well as Advanced Profiles and all levels supported by the standard. In addition, it features MainConcept's extraordinary encoding quality. This Codec Package encodes VC-1 sequences, making it easy to add support for this exciting new format to existing applications.
The corresponding VC-1 Decoder is a software-only decoding solution for SMPTE 421M-2006 (VC-1) video streams. The filter can process VC-1 video streams produced by the MainConcept MPEG Demultiplexer or any other compliant filter, such as the Microsoft® ASF Reader.
