I've been editing a bunch of videos with my system over the past month, and everything has been working fine. All of a sudden, this weekend, my whole system is lagging. FCP won't play a normal (footage-only) time line without stopping, staggering, etc. It will appear to stop, (video and audio frozen) and then play a second or two before stuttering and repeating same thing I just described.
Do you have any thoughts what might be causing this?
Editing on:
Mac Pro4.1
Processor 2 x 2.26 GHz Quad-Core Intel Xeon
Memory 6GB 1066 MHz DDR3
NVIDIA GeForce GT 120
FCP 7.0.3
My scratch drive is set up on a 3TB external, with 1.67TB currently available.
I'm editing primarily video in DV NTSC format
Thanks for your help
