PT8 | HD Quicktime Video Stuck Randomly

[dwaldi]

Hey guys,

I did a search and couldn't find this exact problem mentioned anywhere, so I figured it's worth a shot.

System is a version 3,1 8-core Mac Pro, 6gigs RAM, HD 5 DSP system. Mac OS 10.6.6, PT 8.0.4. When online, the system chases SMTPE time generated by a Rosendahl MIF3 box.

The problem is that for no apparent reason, Quicktime video (coming out of the second DVI port on the Mac Pro) will freeze on a frame while the audio keeps going. Pro Tools has to be restarted in order to fix it. This has never happened in the past.

Some details: The video is 960x540 @ 23.976fps. H264, no audio imported from the video.

Things I've tried:

Trashed PT prefs and databases, deleted Quicktime preferences, changed Host Processor setting to 7 @ 90%, reimported video.

Any help is appreciated!

convert the H264 to something like photojpeg
H264 can kill the CPU

H.264 usually works fine, but if you were gonna try a different codec I'd recommend uncompressed DV, it has the lightest load on the CPU.
