Hey Colin,
Doing a test right now, from an 8bit timeline to h264 QuickTime conversion of a :30 second spot. Seems to be going alright, although pretty slow. Looks like it’s gonna take about 15 minutes on a G4 1.42 dual with 2 gigs of RAM, Tiger and QT 7 Pro.
A few minutes ago I tried doing a self-contained Quicktime and FCP shut down.
I’ll let you know what happens…
