Sound is very choppy and broken when played back but when editing the video in the "trimmer" window the sound plays back perfectly. It occurrs on both my laptop and desktop using a .mov file recorded by an SLR camera. No problem with GoPro .mp4 formats.
I thought I was in the Video Wave by Roxio thread. I am just editing the video and sound and these .mov file formats play back with a choppy, cut out sound but using the trim function the sound plays back perfectly.
