I'm getting the error message Process Finished Unexpectedly when I try to export my video. I've seen others mention this same problem. I have Pro 12.3 version. Nothing will export from short videos to long ones. I shot a stage play which is about 2 hrs. long, and I need to get that to my clients as soon as possible. This is a bit frustrating but I'm hoping someone could help me understand this, and help me out with a solution. I shoot with 3 canon G 20 and Blackmajic Design Atem Studio, I.m Running windows 8, my system is good on specs, but I'm clueless as to whats going on. Thanks in advance.
