[QLab] video crossfade

[Chris Luessmann]

Chris,

I really appreciate hearing you say that. It seems like right now the only
apple machines capable of decoding cross fades between video files are the
Big expensive Mac Pros, or only the newest Macbook pros. I have a mac mini
tricked out with a 7200 rpm HD and 3gb of ram and a 2.33ghz core 2 duo. But
it is pretty much useless, because of the GPU is not ideal. This is only a
problem when cross fading video files at a usable resolution on my final
display. I can play 2 1080p files back no problem on this little mini, but
when it comes to cross fading 2 480p photo-jpg MOV files, it can just barely
do it at 1280x800 on my display.

My slightly older 17" macbook pro with the Radeon x1600 256mb card has the
same issue... But the CPU and Ram and HD are all up to spec!

One last thing. I would love it if my picture files that are larger than
1920x1200 would stop coming up as a white blank screen. again, my macbook
pro can play them with no problem, but when I play them on a lesser GPU,
they just come up white. quicktime opens them fine, qlab's video preview
sees them fine, but playing them full screen comes up blank.

I am using osx 10.4.10 quicktime 7.2 and definitely the newest version of
all the qlab plugins.

I love Qlab, and use it religiously. I would just like nothing more than to
replace all our "Watchout" computers at UCSD with mac minis.
