Hey, I'm having issues with running final cut studio 3 (current) in its full glory on my macbook pro/led 24in setup. I have my mbp to the right and on an aluminum stand (heat, height, style, etc) which I use to display my canvas within final cut pro and I use the cinema to show the sequence, viewer, etc. I am having issues where my video (in canvas or viewer, so it is not monitor specific) will gitter and get horizontal lines across it that are not present in the video file, but only when played though final cut pro 7. They are Pro-Res 422 (HQ) 23.98fps 1080p files (files off of 5D which were converted with the Canon EOS E-1 plugin). I am wondering if this is a crappy graphics card or a crappy hard drive. I can buy a new hard drive, its a bit more difficult to completely replace my mbp in order to edit properly. Perhaps there are some setting in final cut pro you could recommend? or some solutions to maximize video card capability? Any assistance or advice is desired. Again, I have the 2009 unibody macbook pro, 13in 2.53ghz 4gb, and I have a 500GB 7200RPM Seagate. Also, I'm not new here, just new to the forum aspect, though welcomes are welcome (ha!) they are not necessary. Thanks folks.
