    Upgraded to Mavericks, new iMovie is choppy!
    I upgraded my late 2011 MBP to Mavericks and I was forced to upgrade to the new iMovie. It's very slow! I upgraded my memory to 8GB and it made it a little better but it's still choppy on playback.

    Also, when iMovie is open, all my programs slow down.

    Help!

    Hmm.. Can you post the specs of your laptop.
    Also check to see how much the CPU is getting used in the task manager before and after opening iMovie.
    Also how much software do you have loading up at startup.

    Cheers,

    OS X Version 10.9.1
    Processor: 2.3Ghz Intel Core i5
    Memory: 8GB
    Graphics: Intel HD graphics 3000 512MB
    320GB hard drive, 176GB free space

    I can download video and when I play the video from the video library, it's fine. When I select a video clip and drag it to the editor to create a movie, the audio is fine but the video is choppy and lags the audio. I've had to use another computer with an older version of iMovie to create videos.

    Without iMovie running: 97% idle, 3% CPU usage.

    iMovie reports CPU usage from 150% to over 200% when running video. When I run video from the video library, everything is good and CPU usage is about 120%. When running it from the clip I dragged to the editor to create a movie, it runs around 220%.

    With iMovie open but not running clips or editing, CPU usage fluctuates from 80% to 170%.

    Um, no.

    Your old iMovie is still on your hard drive (unless you deleted it, obviously). It's been moved to a folder called "iMovie 9.0.9" (or whatever version you had before you downloaded and installed iMovie 10).

    None of the iLife and iWork upgrades overwrote the previous versions. If you had them, then you still have them.

    (for the record, my copy of iMovie 10 is working fine with no choppiness, but my point is that if you don't want to investigate what's going on with your copy of the new one, you can just carry on using the old one -- it works fine in Mavericks.)
