I'm not too sure what you're actually asking here, but if you don't want the commentary in the footage, you need to record from a different source, as the audio is from that particular YouTube video and can't be edited separately. What i mean is that i have downloaded some footage off youtube. In some cases there are two audio tracks, one is the commentary the other music. I want to separate them so i can delete one but not the other but i cant do that that atm as they are grouped. I got mixed up with my last post, i want to delete the music but no the commentary @Johannas, there are two audio tracks though, im not sure one might be the music and the other the audio?
