I have two long video tracks, of about an hour each. One static camera, and one roaming. Both recorded in real time, at the same time.

I want the track to be the main track and dip into the roaming camera when there is someting interesting.

So basically I have 2 video files.

How can I "Mute" one video track, showing the other at specific key frames. I can't find out how to do this, without chopping the track into small pieces.

The help shows cross fading on the same track, but that's not what I want.

Insert>Video Envelope>Track Mute?

I only have.... "Track Composite Level" and "Track Fade to Color" under Insert>Video Envelope>

Maybe this is a full Vegas only option?

A track composite envelope should do it.

You could also split the track without auto ripple on and just cut out the pieces you dont want

That's what I was trying to avoid doing, but maybe it's the simplest.

Thanks for your help
