I am sure that I am doing something wrong so I looking for help from the experts. I did my first 4k shoot at a Airshow a last week and download Vegas 17 Post two weeks ago. I began editing and Vegas began crashing Windows No Response monitor turns white. And for some reason the Project Media redraws the clips. See attachment. Video is from a Canon Vixia GX10 3840x2160 59.94 MP4 files.
Maybe my settings are not correct but everything work find for HD 1920x1080.
