Jerky Playback CS4

Hey guys,

I recently installed Premiere Pro CS4 and have been getting some weird results. Sometimes when I start a project, it plays back fine and theres no issue. Other times I'll start a project and the video is very jerky (moves forward two seconds, backwards one, forwards two, backwards one, etc) Creating a very bizarre looking video that is extremely difficult to work with. The video itself is fine and can be played in media players as well as other NLE's. Just recently I was working on a project and it was playing back fine. After capturing more material, the jerkyness suddenly started. I can't for the life of me figure out why its doing so. I know my project settings are setup correctly because it was working fine for awhile. Any help is GREATLY appreciated. **Also, my timeline HAS been rendered.

My computer specs are:

Windows XP Pro SP3
AMD Athlon 64X2 Dual Core Processor 3800+
2.00 GHz, 3.25 GB of RAM
Data is stored on a 500g slave HDD with about 35g free.

I'm editing 4:3 60i SD footage (nothing too hard to handle...)

Thanks again!

Jake
 
If your SD sequence is already rendered and your still having trouble playing back on the timeline perhaps you could check if your your 500g slave drive is fragmented. Also hard drives begin to slow down once they fill up past the half way mark.

Good luck!
 
Mines goes like this Jakes as well. It jumps every one second like a go and pause play. I have nothing else running in the Background. Use Premiere Pro CS4. I recently did one that was jumpy as well but at the end of the day it turned out fine. So i don't really want this one to turn out jumpy.
 
Mines does the same it jumps forward every 2 secs. like a slow motion I recently did one that did the same but at the end it turn out fine, I think was because it was short - less than an hour.

Only have Adobe Premiere Pro CS4 running.
 
I am editing using Premiere Pro for CS4. I edited some footage on a sequence with the incorrect settings and am now having major troubles exporting the video.
I shoot HD footage (1280x720, at 24 fps) with a Nikon D90.
What I did wrong initially was to edit the footage with a frame rate of 25 instead of 24/23.976 . When I realized my mistake, I copied this footage into a new sequence with the correct settings and frame rate.
However, now the footage is very jumpy after it is exported. I looked for a feature that would allow me to remove the distortion due to copying the edited footage between sequences with different frame rates (like Final Cut's "remove attributes", "distort"). However, so far I cannot find anything. But, I am hoping there is a way to remove this distortion, otherwise I will have to re-edit the entire video again.
Any ideas? I would love some help!
 
I have been doing:
Export, Media
H.264, NTSC, 1280x720, 23.976 (fps), Progressive
AAC, 192 (kbps), 44.1 kHz, Stereo
VBR, 1 pass, target 6.0, max 10.0 (Mbps)
Multiplexing: MP4, Stream Compatability: PSP

is that enough detail?
thank you!
 
I've got the same problem too, 100% CPU with just playing back DVCproHD 720p 25p...
I've got a Q9400 overclocked at 3,2ghz (Quad) and 8go Ram... That's weird...
 
hey,
so i havent figured out the problem, but the adobe premiere forum/community help area is very helpful.
also i tried uploading the file. once vimeo/youtube etc reencodes it, it plays just fine, even though it doesn't on the computer
