Yes! Thanks indeed. I was beginning to pull my hair out. I’m trying to get my hands on the file as well, but if you could post it that’d be great!!

Hey –
I have been having the exact same problem. I’m cutting a feature on a 8 core 3.2 ghz mac pro with 8 gig of ram.

I have my timeline, canvas etc. on my left monitor (23” apple cinema display) and then i have my browser on the right monitor (also a 23” apple display). I use the right screen as a client monitor when reviewing.

Out of nowhere it started to studder/jitter (with NO errors/dropped frames etc.) when i go into the digital cinema desktop preview on my right monitor. If I move the canvas window from the left side over to my right screen and then do the preview – it runs fine. So it seems it cant handle playing the canvas and the digital cinema desktop preview at the same time on two screens.

I’m cutting red footage that has been converted to apple prores HQ – 2048 x 1024.

Again, everything was working fine for a good month and then all of the sudden i ran into this. I had recently ran the software update, so it would seem that is part of the problem.

Have you figured it out on your end yet?
