Premiere Pro plays back clips in real time and relies on the speed / performance of your hard disk (as well as GPU ) for smooth playback.
After Effects does not play in real time. It creates ram previews and therefore doesnt work the same as Premiere.
Check hard disk for playback speed issues with the free AJA system check software for starters.
Deleting all your media cache and preview files for Premiere is another good thing to do.
HEY, thanks for the advice. I did go thru and did everything you mentioned. Nothing changed though. I did do a small test, and export a small scene, and the jumping was not on there, so that is good, but i wish i could really figure this out... makes it very hard to edit. Anymore suggestions?
Well if the jumping problem isnt there its probably a result of one of the things you did.
In the future do one process then check for results. That way you you can isolate what helped.
If the problem is gone theres little chance we can found out what the problem was.
You failed to mention what the AJA Speed test utility indicates your media drives are playing back at. Crucial information.
Also how full is that media drive and please give me full details on it. Without more info I cant be of much more help.
Heres some guidelines for info needed.
This info applies to trouble shooting Premiere and After Effects. Thanks.
I have 3 drives.
C: which i have my Windows 7. and all my CS6 software. This is a SSD drive, writes at 200mbs- reads at 500mbs ) (drive has 119 Gb total, and 68GB available for use)
E: a 2 terabyte drive , this is where I save all my sequences from CS6, write 163 read 154 (has 1.8 terabyte availabale.)
F: this drive is a WD pasport Drive- connects USB 3.0, here i where I save all my video footages, raw and then rendered , raw music, photos, everything really. (931 GB total, 800gb available) (this drive writes at 64mbs and reads at 116) again, i know that sounds slow, this harddrive, compared to rest, but have had 0 problems up until yesterday.. so it ran fine , since new, and then pooh.
Chose this set up thinking the actual software should be on the C- SSD fast drive.
And the other media away from it.
Im, open to suggestions. Thanks,
