I've uprgaded to Vegas 16 and so far so good. Been a user since version 6. Upgraded mostly for the HDR on my LG 65" OLED and it looks very straightforward and promising having rendered files that display the HDR banner on the display except, the colors gamut ect, are off because I'm not monitoring in rec 2020. The Blackmagic mini-monitor 4k is the obvious choice.
Can someone confirm that it's still not supported. If someone from Magix support could chime in on when this might happen please do.
