Detailed Description

ColorMatrix 2.0 is based on the original ColorMatrix filter by Wilbert Dijkhof.

It adds the ability to convert between any of: Rec.709, FCC, Rec.601, and SMPTE 240M. It also makes pre and post clipping optional, adds an option to use scaled or non-scaled coefficients, and more...
