Weird little playback bug
So I’ve got a dual quad-core Xeon Mac Pro with 8 GB of RAM and two 30″ Apple Displays. What I’ve been doing is putting my Browser, Viewer, and Timeline on my left screen and playing my Canvas on the right monitor using Digital Cinema Desktop Preview (the resolution is set to 1920 x 1200). This hasn’t been causing me any problems until yesterday, out of the blue. It may have had something to do with the 7.0.1 update I ran, but I’m not sure now, if it was happening before or after I updated. Anyway, basically, the playback is really stuttery and poor. I’m playing back using the ProRes 422 (LT) codec, but had similar problems with the ProRes 4444. Should I downgrade back to 7.0? Is that going to mean a total uninstall and reinstall?

Trash your preferences. Use the Preference Manager from https://www.digitalrebellion.com. I saw this issue pop up on another forum and that solved the issue.

BTW, what OS version, QT versions are you running? And what graphics card do you have?
Try Refreshing A/V Devices and see what that does?

Trashed prefs a few times, no luck. I’m running the latest OS (10.5.8) and Qucktime is up-to-date as well (7.6.4). Graphics cards are NVIDIA GeForce 120s (two of them).
trying to repair permissions, see what that does.

Two cards. FCS doesn’t support two cards. Motion and Color don’t work at all as they rely on the cards, and two will conflict, and FCP has many many plugins (FX PLUG plugins) that also rely on the graphics cards, and all sorts of oddness can happen when you try to use them when you have two cards.
You might be running into an issue of having two cards with software that doesn’t support them.

I believe you that it can cause problems, but why would it work fine for 9 months, then crap out? Would the update trigger something that was working (but technically shouldn’t be) into not working like this?

Well, I removed one of the graphics cards and it didn’t fix the problem.

I’m going to reinstall, go back to 7.0. There goes my evening.

Complete uninstall… complete reinstall… loss of all presets, etc. STILL not working.

What kind of hard drive?
Why 1900×1200 for 30″ monitors?

Everything’s playing off of either an internal RAID (for the ProRes 4444 footage) or an external FW800 (for the ProRes 422 LT stuff). But it’s not dropping frames (no warning is popping up). And it only does it if I’m in Digital Cinema Desktop Preview mode.
I put the resolution of the second monitor to 1920×1200 since I’m working with 1920×1080 footage, and making it play back at a higher resolution didn’t yield great playback results. Not much point in up-res-ing the footage when it looks good playing at 1920×1200.
