Hello, I have started to use QuickTime instead of PhotoBooth for my pre-recorded videos. The result is in .mov. The video lasts 1hour. Then I compressed it from .mov into .mp4 through HandBrake. And here comes the problem. The sound of my video (perfect in .mov version) became unrecognizable in .mp4 after the compression. I didn't have this experience before with PhotoBooth recordings. please, could you advise what shall I set up in HandBrake to compress it correctly? In my HandBrake the AUDIO says Track: 0:Unknown Codec: AAC (CoreAudio). how do you compress your videos of 1h to upload fast later on YouTube with all preserved? thanks a lot!!! I am using Mac OS Mojave
