Final Cut Pro 2.0 and CleanerA quick solution to luminance issues
Last week we received a Matrox RTMac card to help streamline our edit sessions and to provide some real-time processes to our system. We also upgraded to the latest version of Final Cut Pro that takes advantage of the RTMac's power. Everything was working fine until I added a graphic layer on top of my video. All of a sudden, I was experiencing a luminance shift every time I did a dissolve or added a second layer of graphics. This resulted in some hair pulling and gnashing of teeth as I started cursing all computers and NLEs as a bane to everyone doing post work.
A fast look at the Apple, Matrox, and WWUG forums proved that I was not the only one experiencing this problem. I have found a solution and believe this may be a fix for the 95 percent of you who are fighting this very same problem.
The problem is actually not with the RTMac or Final Cut Pro 2.0, but another very common program that video professionals may have installed on their system. Media 100's Cleaner (4 or 5) appears to be the culprit. Or, more specifically, some of the Codecs that were installed when Cleaner was put on our system. It appears that some of the codecs force Final Cut Pro sequences to render in and lock in RGB mode, thus causing the shifts in color.
The solution? Turn off the RadDVCodec and The RadDVDecoder in your Extensions Manager. Upon restarting the system, I no longer experienced this luminance shift during transitions or layering of graphics. If you are still having problems, the RadDVCodec extension may not be the only one forcing FCP to render in RGB; you may need to turn off several other Codecs to solve the problem. You should also make a mental note to turn these extensions back on before going into Cleaner for any compression work (or saving a separate extension set for use with Cleaner).
This quick solution worked for our editing system, and it may also be the answer for the thousands of others who are suffering through the same nightmare.
