Rick, he is using the Ursa Broadcast, not the UM/Pro 4.6. The Ursa Broadcast is the 1-inch (13.056x7.344mm) UHD sensor, so only shoots full gate in UHD (3840x2160) or downsampled to HD 1080.
Broadcast cameras normally can be set to TV “Safe Area” with framing framing guides (originally known as overscan, never have seen a Broadcast type camera EVF with adjustable guides, only the pre set one (but it has been a while since I last used one). A Studio Viewfinder (Monitor) is more adjustable and has custom guides, and room for the required X and Y axis control knobs. EVFs were normally used on ENG cameras with fixed aspect ratios, which the EVF mirrors.
Broadcast type cameras are built for the major majority of user applications, and not able to meet every one’s odd applications. The EVF was originally made for the Ursa Cinema camera and later used in the smaller Ursa Mini Cine cameras.
I used to use black thin card stock to make EVF guides where I wanted the aspect ratio different than the preset. Gaffers tape also works. Cinematographers started out with film and optical viewfinders, where masking the viewfinder with mats or tape was the normal workflow, digital EVFs just replaced the optical bit with a mini CRT and later LCD displays with the normal setup controls and adding image peaking to help with focus. Aspect ratios then were fixed by the camera and its matching EVF.
