I can't explain the crash, but presets are just a starting point. You can create your own if the ones supplied aren't sufficient.
I can repeat the crash over and over again. I know it's not my machine because PP CS6 and all other CS6 programs run fine.
Asus P9X79 LE
16GB DDR3 1600
1TB WD hard drive
Nvidia GT 630
It could be a bad install. I can't replicate that behavior on any of the four systems I use for editing. They all work just fine with this feature. And I can't recall anyone else reporting this crash, so it is likely something went wrong on your system.
Were any multicam projects converted over from PP CS6?
I had installed PP CC on a virgin system and when it continued to crash, i removed it and put CS6 in.
