Why Do I get Choppy Playback in Premiere Pro CS6

Before upgrading from CS5.5 to CS6 I wiped my computer and started from scratch. When editing 4 angles in CS5.5 I never had any problems with playback... even after adding titles, effects..

In CS6 I have my 4 files set into a multicam sequence but when I play back and start cutting from cam to cam it gets choppy.

I am running:
Windows 7 64bit
On a Dell Studio XPS 9100
Intel Core i7 930 @ 2.80GHz
12.0 GB Ram
ATI Radeon HD 5800

I have my memory preferences in PR set to 12 GB Installed, Ram for other aps = 3 Ram fpr PR 9GB, and it set to performance

Any help to speed up and render this proper would be great, Still have to add color correction, titles, logo.

    m2ts= Sony HDR-XR550 & Sony HDR-CX550
    MP4 - GOPRO HERO HD2
    MPG - Canon XLH1 Tape imported with PR CS6

    I have razored the Canon file every time there was a stop and start with recording and synced the clips with the rest of my file.. I have also re-exported each of the 6 Canon clips into there own individual MPG file and re-synced same problem


    OK.

    There is an issue with longer AVCHD media that makes CS6 largely unusable at the moment.  You may want to transcode that to something else while Adobe works on a bug fix.  I recommend the free and lossless UT codec.

    I have problems with M2T files as well, but the fix shouldn't have to be transcode them to Mpeg. Premiere is supposed to handle files of varying formats in the same project.

    I generally shut the program down and go into the Video previews folder and delete them.

    Then re-open Premiere and wait for it to re-create the peak files. 

    As for choppy playback in the multicam viewer check your hard drive cache.

    I have a pretty powerful PC and it was brought to a crawl by the Hard Drive that came with it, which I found out only had a 16mb cache.

    I recommend installing a second Internal HD with at least a 32mb Cache or higher and put your video on that. (You can get a Western Digital HD for under $100)

    However make sure you have the scratch files going to the C: Drive (this will help with render speed later.)

    I edit videos that come off Canon XF Series Cameras, each video file plays back at 5mpbs so in my case if you are using the multicam editor you are playing back four videos at the sames time plus a fifth which is the preview screen. So that's most of the HD cache right there, if you add the PC trying to run the software you're really taxing the HD.

    So the best bet is buying a second internal drive becasue most external drives don't have enough cache memory.

    I had the same issue. But I just rendered the effects i did....by going to the top, SEQUENCE and then RENDER EFFECTS IN WORK AREA....and then boom, was running smoothly. And then you see that the red lines above your content is not green.

    It's working smoothly now...for the time being.....

    I'm still having shutter issues with 4 GoPro 720p 60fps videos - I have even clipped them down to 1 minute each - still no go - 5 seconds into playback and everything locks up.  Intel i7 8gb ram 1gb on video (Mac) AMD 3.2 Quad 12gb ram 2gb on video (PC)  Something we are doing is wrong - I don't know (personally) anyone that can get more then two/three at most to work? I see people all over the net frustrated to no end with this so I know it's not just me?  I know some of you say you get it to work, and I saw it work at NAB - but in person - mope and I know folks with the best of the best and 38gb running files form an SSD drive - and still - no go?  Seems I'm just chasing another Adobe Ghost!

    When I run PR and it is choppy if I go to task manager/Performance it is only using 3.85 GB of the 9 alloted to the program.
    also getting about 13 "events" that say a low level exception occured in: Adobe Player

    The yellow bar above my clips in the timeline is missing chunks. How do I render or replace missing frames?
