I tried some things with this new option in VMS 16 without being able to read something in the manual or helpfiles.
So now it looks to me an option that I cannot use because it worked with me with a 4x too big screen in which I could not see any changeable option.
When I tried to save a made file it turns out to become an unreadable small file.
So I'm forced to don't use this new option and stay with my beloved OBS for making screencaptures with and for Vegas Movie Studio and Vegas Pro.
