Cut Pro 2.0 and Cleaner
A quick solution
to luminance issues
I have recently become addicted to Final Cut Pro as my
editing software of choice. I can't believe how simple yet powerful
this $1,000 package is. From my recent post projects, I have
discovered that this NLE does everything I need it to do and
more. In some of the other NLE systems I have worked with, I
was constantly sending stuff out to After Effects for graphic
treatments. Not so in FCP, as I can have a practically unlimited
amount of video layers to mix and layer graphics quickly and
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
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.
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
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).
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.
