Thanks for the tips Nat! Also thank you borate for your input.
After reading the second method you mentioned to close the gaps I think I understand what you suggested but I was wondering also if this would work -
First I would delete all the audio files from Audio Track 1 (the muted sound clips)
Then move the song I'm using (Audio Track 2) up to Audio Track 1
Now Video Track 2 and Audio Track 2 would be empty
Then could I drop the missing segments on to Video Track 2 and move them to about where they would have been if they were not missing and trim some of the excess
My question is if I left some of the Video on Track 2 overlapping Track 1, naturally the video will play Video Track 1 and not the overlapping portion of Track 2?
Would this way allow me to fill the gaps in without actually editing any of the clips in Video Track 1?
Sorry if this is a bit confusing I'm still very new to video editing, thanks again!!
