I thought these problems would go away when I upgraded from PD9 to PD 11...silly me. Is there some magic secret to editing video (sharpening, saturation, white balance, lighting, transitions) that does not cause your video to become jerky and get out of sync with the sound. This makes PD almost worthless for my needs ! Any suggestions to allow me to use the tools that come with PD11 without all the problems it creates ?
