Playback Lag in Premiere Pro CS6 for Mac

May 25, 2013 5:41 AM

Tags: #problem #pro #mac #premiere_pro #premiere #cs6 #project #premiere_pro_cs6

I'm editing a project in Premiere Pro CS6 for Mac, and the playback is really laggy. Its fine if you're viewing one long clip, but it gets really laggy when it switches between clips. The sound will play, but the playback screen will be frozen on the last frame from the previous clip. I use the latest thin model of the iMac. Can anybody help me?

    >editing a project

     

    I have read that it takes a "monster" computer to edit RED video... is that what you are doing?

    OK... AVCHD takes a LOT of computing power to "effectively" edit

     

    So... some Information FAQ questions that you did not answer

     

    What version of Premiere Pro? Include the minor version number (e.g., Premiere Pro CS5.5 with the 5.5.2 update)

     

    Tell us about your computer hardware

    -such as... what CPU... i3 or i5 or i7

    -such as... how much installed memory

    -such as... how many and what speed hard drive (one 5400rpm drive... or...???)

     

    Are you using Mercury Playback Engine GPU Acceleration?

    >Premiere Pro CS6 with the 6.0.0 update

     

    Is there a specific reason you have not applied the bug fix updates?

     

    All Adobe updates start here and select product, read to see if you need to install

    updates in number order, or if the updates are cumulative for the individual product

    http://www.adobe.com/downloads/updates/

     

    Also, only having one hard drive means your computer is having to "struggle" with file operations

     

    An EXAMPLE concerning trying to use only ONE Hard Drive for Video Editing
    .
    You are a music conductor, with a baton that you use to point to various parts of the

    orchestra... this is like Windows pointing to various parts of the hard drive to do

    Windows housekeeping or to load program segments for various functions
    .
    Now, at the same time and with the same hand... while still using the baton to conduct

    the orchestra... pick up a bow and play a fiddle... this would be doing something with

    your video file at the same time as all the other work
    .
    You as a person cannot do both at the same time with the same hand
    .
    A computer is a LITTLE better, in that it can switch from one kind of task to another

    very quickly... but not quickly enough for EASY video editing
    .
    You need AT LEAST two hard drives (separate drives, never a partition

    http://forums.adobe.com/thread/650708 for more on partitions) with Windows (or Mac OS)

    and software on your boot drive, and video files on a 2nd drive so the boot drive is

    not slowed down by trying to do everything
    .
    External eSata or USB3 are both fast enough for video editing... eSata is better -

    Do not try to use USB2 for video editing, it is too slow

    Can't speak to the Mac platform, but on Windows machines, including high-end Windows machines, AVCHD and AVC-Intra footage can display the kinds of lags you're describing in PPro, when moving from cut to cut.

     

    If you have an earlier version (5.5, 5.0), you might want to try it:  this problem supposedly didn't exist prior to CS6.

     

    Or, as a last resort, transcode everything to ProRes or similar intermediate codec.  However, since your one drive could be a problem, you want to do some tests, first.....
