    Jerky playback in PE 12


      I recently purchased PE 12 for Mac. I am happy with the software, but am having a few issues. I have a Macbook Pro that I am using to edit footage taken from a Sony Action Cam @ 1080p 60fps. I am using the NTSC-AVCHD-AVCHD 1080p60 project settings. When playing back the video in the preview window, it isn't necesarilly jerky, but it skips an insane amount of frames. Audio is fine. It isn't allowing me to render the footage (no orange line above the video clips). I have tried adjusting the playback quality between Automatic & Highest, to no avail. Specs on the computer are:


      2.53GHz Intel Core 2 Duo.

      8GB Memory

      500GB 7200 RPM Hard Drive

      OS: Mavericks


      I'm really hoping this is a codec issue and not an underpowered machine issue.


      Any suggestions?


      **On a side note, whenever I play the video in the preview window, I am not seeing the CPU max out, there isn't excessive disk activitiy, & the memory still has room to breathe.
