I have had several share on youtube getting flagged for copyright issues only due to the music on the radio playing, so now i mostly mute the sound in post production.
Dont need that much in the winter time as during those months i do not use my radio much.
A bit Amazed i have not heard from my last Vantrue upload as it to carry the music.
But it could also be a setting for the youtube channel i think, when i got copyright warnings it was on my old YT channel i deleted last year.
Most video editing softwares let you do interesting multi camera edits, and most can also Sync up these different recordings automatic, and also i think most can also do a color mixing to even things out if the footage from the different cameras are not the same looking.
Something like that will also let you use the sound of one of the cameras act as the main sound track, and then you just switch in between the different cameras for visual effect.
BUT ! that is the more advanced stuff that i dont really use, the above video are just changing back and forth between the 2 interior cameras on the N5 system, and as i recall i kept the sound from each camera so the sound track also change back and forth between the 2 cameras.
