I am sure It used to be possible to manually edit the Opacity level via the envelope - i have not used the software for approx 2 years and it has been updated a number of times - I used to be a Vegas user and cannot remember if I have got myself confused!! - I cannot find how one can add nodes to the Opacity level envelope - was that possible before? I can do the fade and overall Opacity but I cannot have the fade to my liking, as I could, if I added nodes to control the fade, if you see what I mean.
Also is it possible to add an envelope to control say the level of an effect - the amount of saturation for instance? I am sure (well sort of!) that you used to be able to add envelopes to control certain things.
Many Thanks
