I'm editing a project where three HD cameras captured a play simktaneously. So my timeline has three video streams, and I cut between them. PLayback is a bit shoppy, but until a day or so ago, not terribly so.
Thing is, now my machine seems to chug even when I'm making changes on the timeline. I after a clip on the timeline, and suddenly I get that littleblue disk-access circle, and after about ten seconds the timeline changes to reflect my work.
I have no idea what could be causing this. I've shut down just about every extraneous background appplication. I've even tried creating a duplicate project of the last third of the play, so I'm working with fewer files, but that didn't help. My machine has 16 gig of ram, runs am AND Phenon II quad-core processor, and I'm using an NVIDIA GeForce 670 which has a LOT of CUDA cores. So this suddenly slowdown is a real mystery to me.
Are the software you run other than Premiere also running more slowly? From within PPro, are encode times worse, if its possible to compare?
Were you possibly overclocked and maybe you lost your overclock due to some change in the BIOS?
Rebooted, no change. No noticeable chugging on other applications (including Crytsis 2). I've never overclocked, so that's not an issue.
It did occur to me that, maybe, one or two of the video streams may have acquired an unwanted video effect: I've found that I can accidentally change tyhe opacity if I click on the timeline in the wrong way. But everything seems OK.
But I truly wish that my system could handle hi-def video well. It's a fast system. Heck, I should be able to handle multicamera editing without much of a problem. Only ways to make it faster are a new CPU or maybe a RAID drive system. But this problem was very, very frustrating.
