FCP 10.1 slow timeline and editing - Any suggestions to improve speed?
Recently updated to OS X 10.9.1 and FCP 10.1. Now experiencing very slow editing and movement in timeline. FCP is responding some 2 to 5 seconds after providing an editing command. The slowest response is to scrolling in the timeline - 2 finger scroll does not respond for up to 10 seconds after doing it.
Render times are fine and similar to previous FCP X versions.
Never had this problem in previous versions of FCP X.
So far I have done the following things based on forums and a call to apple support(?).
Deleted all plug ins.
Started from scratch a project that I was half way through and imported all clips from scratch to a new Library (external Hard Drive).
Deleted FCP and reinstalled including deleting all preferences.
Timeline is quick in the early stages of the project but gets slower as I progress - about 3 minutes into my project now (approx 200 clips) and editing time is becoming impossible.
Am using Mac Book Pro with 2.5 GhzIntel Core i7, 8GB 1333 MHz DDR3, Intel HD Graphics 3000 512 MB.
Anyone able to assist with further suggestions?
Thanks
