Just purchased Vegas Pro 22. The further along I get when editing a video, these strange pops, clicks and other noises start to appear. They are not in the original recorded audio. I am working with an older PC with 8gb of Ram and Basic graphic card. Could my low end PC be the reason. I was using Vegas Pro 18 for a long time and had no problems at all until I ruined it when trying to add external VST effects.
