I just finished a Vegas 16 historical project that is over 1-1/2 hours long that used all old 16mm color film from about 50 sources mixed with graphics and color slides. So I had to use almost every CC and image enhancement effect in the works — Plus Neat film de-graining.
It would be stable for long periods at a time and then suddenly go ‘white screen’. It’s hard to say if the thing that triggered it was any specific category of action on my part.
So frequent clicking on the save button became the norm. Being an escapee from using Premiere since 1997, I am happy overall. But save, save, save. The restoration option, after restarting the program, doesn’t always get you success.
