Does it have black screen when recording internally and connect to hdmi out? On the V1 I definitely saw black screen when connected to the screen which is a shame, but this R50V seems to have latest codec from R5II and not based in previous one.
This is the only thing that kept me from switching the E10II out at this stage til more info coming out (ie the bloody user manual!
R50V can connect to usb-c as UVC webcam up to 4k60p which is nice, and can also be powered by the same usb connection, that solved the power issue for current cameras acted as webcam.
