Fired up Vegas 14 for my first editing session tonight.
Spent the last six hours editing a 3D video, saving frequently. I had a rough cut done, end-to-end, SAVED, and was viewing it when it occured to me to watch it full screen. I first set the preview mode to right only, but the full screen mode showed side-by-side and flickered badly. I set it back to project setting (side-by-side fulll) and it was displaying fine. Then it occured to me to try anaglyph. This time it went back to side-by-side full, flickered, and froze. No response to the escape key, nothing. I fired up the task manger to see what I could see, to no avail, so I selected the vegas task and hit the switch to button and vegas crashed outright.
I had two vegas projects open at first, the 3D project and another where I was loading some 360 view clips to check their synchronization. I closed this latter project after the first full screen view attempt. When I restarted vegas it autorecovered this project, not the 3D project (the one actually running during the crash). When I opened the 3D project almost half my edits were gone, even though I'd saved it.
So...in a nutshell:
Full screen preview does not conform to requested video preview mode. (this worked in VP13).
Full screen preview mode crashes.
Hitting the save button doesn't reliably save the project.
Vegas unable to auto-recover my project.
Aaaaargh!!!!
