Premiere CC 2014 laggy
Hey guys,
I’m having some pretty serious issues with premiere flipping out on me.
I cant get through an edit session without at least one problem popping up that bewilders me but here is a break down of two of the main issues that I have noticed over and over again.
1: really slow response times in the playback window. I will hit the spacebar to start playing my timeline and the program window just goes black. It stays black for about 4-5 seconds while the audio plays through in real time. After 4-5 seconds it will kick into gear and the footage is displayed. I have noticed the CTI is running through the timeline in real time while the screen stays black.
2: Audio drops out then comes back in a few seconds later while Im playing back the timeline
I get other slightly different issues at different times like the program monitor stops playing the timeline and goes green. Or it will just freeze all together while I can still hear the audio playing back real time.
I have also noticed when i apply effects and dial in some settings it takes the program monitor 2-3 seconds to catch up. and update with the right changes.In terms of performance elsewhere everything else is fine (I don’t get any lag in the source monitor or in the timeline from dragging clips around.
I thought this issue was due to HD speed (I was originally cutting on an internal 72rpm drive and OS on a separate 72rpm drive.
I have since installed a raid 0 (3 72rpm drives set up with disk utility in mac osx) with an ssd for OS and cache but if anything performance is worse.
The ONLY thing i can think of is the third SATA drive i bought to build my RAID had a slightly different numerical number on it, it was still a WD 72rpm SATA drive like the other two but for some reason it had a different product number on it which tells me it is a slightly different model/type of drive…could this be it? Blackmagic disk speed utility is telling me im getting around 314mb/s write and 338mb/s read speeds currently and Im cutting dslr footage so surely thats fast enough?
Full specs and footage details below, any help would be great as I am now quite often getting slammed at work because it is just so hard to get jobs out the door compared to the good old FC7 days!!
Cheers
