Thanks for everyone exploring the demosaicing options. While it is assumed our current filters where selected for performance, that is not entirely true. While there are some performance options, bi-linear and matrix 5x5, the others where the render grade filters of their day, finishing films from My Bloody Valentine to Slumdog Millionaire. As computer power has increased even more advanced algorithms are being used.
The problem we have is GoPro CineForm codec is not open source, while we are working on a SMPTE standard version of CineForm as VC-5, we can't use any GPL code -- although LGPL (lesser GPL v2.1 is fine as a dynamically linked library.) Several of the offered links point to GPL code, which sadly prevents its use. Stuck again.
One of the reasons the CineForm RAW workflow is so much easier than everything else, is the controllable demosaic is built into the decoder, effective making every tool RAW capable. So I still look for a friendly license (MIT & LGPL) or an inexpensive commercial license that could be included in a free decoder distribution.
