Randomly dropping frames
I am experiencing random dropped frames; this occurs while playing in the timeline and edit to tape.
By random, I mean, I can play sequences and edit to tapes for hours without problems; then the same sequence will throw up drop frames every few minutes, then go back to no dropped frames.
I have tried turning off mirroring to desktop while editing to tape and turning off External Video while editing; neither seem to make a difference.
I am playing in Safe RT, High-Playback Video Quality, and Full-Playback Frame Rate.
I am working in a ProRes422 1920×1080 29.97 sequence with a mixture of ProRes422, ProRes444, and XDCAM 422 1080i 50Mb, my sequences have a TRT of 00;30;40;00.
For troubleshooting I have tried all ProRes422 & ProRes444 footage in a ProRes422 sequence, and I did not notice a difference.
Has anyone else ran into this kind of problem with the below versions and cards?MacPro 2×3.2GHz quad
10.6.8
8GB ram
GeForce 8800GT
FCP 7.0.3
QT 10.0
Kona3 – 10.1 NDD
Connected to SAN with Read/Write speeds in the 400-500MB/sec (my sequences are pulling ~30MB/sec) -

Has this started to happen recently? The 10.1 drivers for the Kona are mostly for AVID users and it might be worth trying the previous driver. The other thing I spot is the NVIDIA card and 10.6.8 . FCP is optimised for ATI cards but can work with NVIDIA. From memory there were some posts about needing newer drivers for NVIDIA cards with 10.6.8 . This OS upgrade was purely for the Apple apps store and FCPX so it is not an OS upgrade that is helpful for a legacy FCS3 system and particularly for those not using ATI cards.
So check the graphics cards drivers first and then also try an earlier AJA driver set.
