I'm relatively new to FxPlug programming, but I did notice something
strange. It seems that in Final Cut, it reduces the red and blue
channels in my image giving it a green color cast. Once I noticed
this I stripped the plugin down and found that even when I simply send
out exactly the pixel values it sent in to me, it still does it. It
does it whether I ask for RGB or YUV. If I switch codecs in Final Cut
to something like Video, then it doesn't do it, but if I'm in any of
the DV codecs, it does. Is this a QuickTime bug? Something to do with
color space conversion on rendering? Any help or suggestions would be
appreciated,
Trevor,
I assume that you're writing a filter plug-in. Did you base it on the
“FxPlug Filter” Xcode template? Do you see this problem if you just
build the template unchanged? It would be helpful if you could start
with the filter template, and then modify it just enough to make it
reproduce the problem, and then mail me a copy of the project.
