Jerky XDCAM clips on QT 7.5.5
Hi everyone,
I recently upgraded my QT 7.4.5 to 7.5.5 and now my XDCam sequences (exported from FCP “under current settings”) OR raw clips converted to QT through XDCAM converter, look a little jerky when played back full screen on Quicktime. This never happened before. Any ideas? Anybody experiencing the same problem?
MacBook Pro 2.2 GHz Intel Core 2 Duo / 2GB Memory
Codec: XDCAM EX 1080 (24p, HQ, 35Mb/s VBR)
I am monitoring this through my laptop display.
The file is stored in my external hard drive. (However I have tried storing it directly in my system drive, an additional external drive, through FW400, FW800, USB, always same result)
I have tried viewing clips that were created BEFORE the upgrade. Same result.
I downgraded to QT 7.4.5 today via Pacifist and that did the trick. However FCP wouldn t open (it told me it needed QT 7.5.5) – i guess when I first upgraded, something in FCP changed that a downgrade would not see. So now I m back to 7.5.5, same issue.

FCP 6.0.3 works fine with QT 7.5 and XDcam EX works great with it.
I did not install latest FCP because it requires QT 7.5.5, and that version has lots of problems.

I just asked you over on the Apple forum if you are up to date with Pro Apps updates?
Good Luck

Hi Hernan,
I work with a MBP and some ESATA HDs editing EX-1 with FC 6.0.5 with QT 7.5.5 and everything runs really smooth.
The only think I can recoomend you (to everybody) is a regular maintenance. Repair permissions and clean the directories of all your HDs (starting by the System HD) as often as you can.

Thanks Rafael,
I have been trying to do exactly what you recommend. I repaired permissions today yet again. Still no improvement. I guess I’m gonna have to call Apple on Monday, but I worry this might be some sort of XDCAM-codec related problem that they may not be able to help with. Still I’ll give it a shot.
Thanks!
