After a lot of time spent trying to import zcam 4k mov. I've come to the conclusion neither vegas 17 or 18 can do this I have tried import mov files in preferences reinstalling etc and it either crashes on trying to import or it will import 1 or 2 files out of 12 the rest won't play and some don't make it at all My computer is 4k is MSI GE Force GTX 1070 SLI
