How do you add points to the composite level envelope of a track in Vegas 13? I have read that I ought to be able just to double-click on envelopes to add points to them, but this isn't working for me.
Works here in V13. First right-click in the properties area for the desired track and hover over Insert/Remove Envelope. Then tick on Composite Level so there is a check mark. The composite envelope line will appear at the top of the video track. Then double-click anywhere on the envelope line and a point (box) will appear.
Thanks for your replies, but neither of these methods is working for me. I have tried closing and restarting Vegas, but that has not change anything. I can see the envelopes in the two clips I have on the track I want to work with. When I mouseover one of them, a pop-up tells me the opacity, and I can drag the envelopes up and down with the mouse. But when I double-click on it, nothing happens. And when I right-click on it, I get no contextual menu.
It sounds to me like you are dragging the event opacity instead of actually adding a composite envelope. Each event has an opacity that you can drag down from the top but they aren't actually envelopes - it's just a master opacity for the event.
Thank you everyone. Yes, I was just changing the event opacity. I have now discovered "Show envelopes" (ctrl-shift-E) in the view menu, which has made the envelopes visible.
