Choppy video playback
I’m experiencing choppy video playback on the timeline in Premiere Pro and I’m having a tough time trying to figure out why…
The source footage consists of .mov’s that, even aftering the audio has conformed and the timeline rendered, still playback strange. The audio sounds fine, it’s just the video that’s screwy. It does the same thing whether it’s on a portable harddrive or the master drive on the comp, there also seems to be no difference between a computer with half a gig of ram versus 2 gigs.
Perhaps there’s a setting I should know about? Does anyone have any suggestions? Any feedback would be greatly appreciated.
Thanks

Many things can affect playback. You CPU mainly, as well as the amount of hardware acceleration your video card can provide.
Then, there are the services / programs running in the background.

Thanks Vince,
So far I’ve tried this on a 2 GHz Intel Core Duo processor and a Pentium 4 CPU 2.40 GHz processor. In both instances I made sure that no other programs were running. The thing that baffles me is that I’ve had total success using Premiere Pro in the past on both computers. I’m not really sure what I’m doing differently now. I guess just the .mov’s as source footage, plus they’re a bigger size (at almost a gig each for each imported file), than I normally play with in Premiere. Hmm.

hmmm, Premiere should be able to handle those pretty nicely. I sometimnes work with uncompressed footage at 200 gigs+, and once rendered it’s pretty smooth, with the occasional skip .
Once rendered you are really looking at DV files anyway, so it shouldn’t have to do with the .Mov format. It could be an antivirus or software firewall issue as well if the same are installed on both computers. The antivirus especially since it monitors all files access in real time.
I would do a Ctrl+alt+delete, and chhose the task manager and then performance, and take a look at the cpu load, I’d be ready to bet that it’s maxed out.
Now, you didn’t mention what type of graphic card you had. If it’s the onboard type, it’s likely that the CPU is taking the load for the video acceleration as well.

Oh man, I’m an idiot. Somehow, through all the steps I went through to get this footage into Premeire, I ended up making a version of one of the source files with a frame rate of 1.87/sec. It was the frame rate the whole time. Argh.
Thanks for all your help Vince,

That must have been reaaalllly slow then 😉
