For almost a month I have been fighting FCPX trying to discover why I was getting a stuttering timeline and almost handed in the towel when I happened across a thread on Creative Cow talking about this very problem.
I seems to be the CUDA card that causes the problem, I had inserted an Nvidia Quadro FX4800 card about a month ago in order to engage the Mercury engine in Premiere ProCS6.
Unfortunately this very same card has caused FCPX to produce a stuttering timeline which is cured by re installing my ATI 5800 graphics card.
It seems like both Premiere and FCPX are now poles apart with separate drivers needed for the Matrox MX02 and specific graphics cards needed for the NLEs themselves.
I was almost convinced that Premiere was my chosen NLE… till I tried to recall a project yesterday when it stopped three quarters into the data recall and never continued. This put me off Premiere big time so my only choice has to be FCPX.
Fortunately I do have some working experience with FCPX and I am getting to like it especially all the plug-ins that Premiere is now lacking.
Update : I am now using Black Magic’s Intensity Pro card which stops me having to fart around with the Matrox MX02 heap of mince… for £130 I now get full 720 50p monitoring in sync and live ingest from any HDMI camcorder via Media Express…fantastic.
