I’ve been struggling with this all day and fortunately received this how-to from a friend at MediaStorm production company….
So what you need to do is grab the video clip, move it to where you want it, then with the left mouse button still depressed, press and hold the shift button. Then take you’re mouse and slide it down onto the audio of the clip. As you slide the mouse down you’ll notice that the audio follows your mouse to whatever track your mouse is on.
This sounds complicated but I was told I’ll get used to it…and it works too!
