i'm new to vegas pro and for some reason I'm unable to unlink the video and audio from a clip. I was told all I need to do is press the "u" key but that doesn't seem to work. Also when I right click "remove from group" is unclickable (not bold). I'm not sure what the problem is, am I doing something wrong? I also notice when adding other audio or text it deletes everything else in that time frame and I don't know why is there a setting I need to turn off somewhere?
I'd really appreciate any help
