The Videum WNV1 codec is a video codec that was developed by Winnov. This was for use in their video capture cards. The codec was designed to provide efficient compression of video data captured by the capture card. Then allowing it to be stored or transmitted more easily.
The codec also uses wavelet-based compression much like the ADV1 Loronix Wavelet as well as the ADV1 codec. There is also the Ligos Indeo Codec which all used a proprietary codec. This to achieve its high compression ratios, which makes it well-suited for compressing video content with minimal loss in quality. See also the CFCC codec and CGDI codec.
