Rick, you're not being helpful and I think you're even being a bit condescending. I did yet another search after posting yesterday – and perhaps my subconscious thought of new keywords to try, because I've found a third-party product that does EXACTLY what I want. It automatically removes all pauses from a video track (or tracks) based on an audio threshold that you define in advance. It also checks for audio clicks at the trim points to make the cuts cleanly. This forum doesn't seem to be particularly helpful – full of people saying it can't (or shouldn't) be done; so if there is anyone who seriously wants an automatic way to remove silence bits from a video then please contact me privately for specific info.
