I have been using Videowave to create video on Roxio NXT4. I have put together Video Track using numerous video clips. I have also added am audio track. The video clips all have sound. I don't want to mute the sound which I believe I could do by putting in the video as an extra layer rather than video track layer. I want audio track to be main sound but with background sound from video track. (The video track is composed of sports clips with background crowd noise reactions and the audio track is motivational song). Can anyone help.
