Which version of the program are you using?
What model of camcorder is your video coming from and what format and resolution is it? How did you get the video from your camcorder to your computer?
What are your project settings (under the Edit menu)?
Are you running the 64-bit or 32-bit version of Windows 7?
Thank you for all of the details.
While editing is much more intensive an operation, than simple playback, your laptop should be more than adequate to handle that GoPro footage. Even with but a single 7200RPM SATA HDD, you should still be able to edit that smoothly. Nothing jumps out, regarding the OS or the system.
Are you running any real-time, active-scan anti-virus, anti-malware, or anti-anything programs, while editing?
Am I correct in assuming that you let PrE 11 choose the Project's Preset for that material?
What is the Project Preset that it chose?
When you drag the footage to the Timeline, is there a yellow line over the Clips?
running norton 360 in background
using the projects presets choosing NTSC-AVCHD-AVCHD 1080p60
System automatically chooses the NTSC- AVCHD Full HD 1080i 30
I used Cineform Studio to convert the files before importing them into adobe.
what is weird is the thumbnails in organizer, the playback there is worse there than in the Pr elements editor.
i had to download something seperate so that i could have a project in 1080p 60fps.
everything i have found about choppy playback is a result of performance of the machine which cleary this is not my problem. the goPro stuff i have transformed my files so that adobe shouldnt have a problem.
"i had to download something seperate so that i could have a project in 1080p 60fps."
This could be part of your performance problem. You should not have had to add to the program or install new codecs to edit this file with version 11.
"the goPro stuff i have transformed my files so that adobe shouldnt have a problem."
This could also be part of your problem. What program did you use to convert the Go Pro footage? What did you convert it to? Often when people convert video, they actually end up making is LESS rather than more compatible with the program.
On some camcorder and GoPro sites it is suggested you use GoPro's free CineForm Studio editing software. One of it's dozen or so features is to "Convert GoPro H.264 MP4s into editor friendly CineForm AVI or MOV files" (http://gopro.com/software-app/cineform-studio).
If the OP is using this, it seems to me that the project preset may not match the output of the GoPro software. Since GoPro says there is a choice between AVI and MOV, it appears output can have a few varieties. This may be even more true if he "added something special" to make it into 1080p60.
Perhaps the OP can go back to the GoPro software, output a few of the choices and try to bring those into PrE11.
so fore some reason when installing Pr 11 for the first time the 1080p 60fps does not show up in the Project preset when installign in Europe so the adobe fix is to download a seperate file an insert it into the settings ->progect preset file so that the system will now have that project preset recoginzed.
so i tried avi format from Cineform and that was a improvement but i had a subistantial loss of quality after rendering, the mov format was similar results.
what i have found that works is altering the reslolution in Cineform to the supported movie preset dowingradign 1440 @50fps to 1080 @ 30fps
but the real solution going forward will be Final Cut Pro on desktop.
