CS4 Premiere Audio and Video Out of Sync Mac
Video My Life Jun 21, 2010 8:53 PMHi everyone. I import AVCHD assets from my Sony HDR SR8 into CS4 Premiere on my Macbook Pro 17. Upon playback the audio plays before the video, even to the extent that the audio is finished before the video. I am capturing to my one and only hard drive on my Mac using the USB port on the Mac. Are you able to help me figure out what I am doing wrong? I assume I have done something wrong during the set up process. Here are the particulars:
