When select File/Render Video the Dialog box is extremely slow. It might take 5+ minutes for the dialog box to appear. When trying to change any settings it might take another 5+ minutes for PS to think. Just spinning cursor and no action. I checked the task Manager, PS is taking only 10-12% of CPU time and only 274 MB of memory. When working with big PS files it would take all allowable memory: 10GB
System info:
Windows 8
Intel i7 quad CPU
16GB memory
PS CC 2014.1
Is there a PS settings/Preferences for Video?
