Jamie, yes the image is set to use Dynamic Range Film without LUTs applied.
BMVA12G7 has the 4.6K Film to Video LUT selected, but Display 3D LUT is Off. The UM4.6K has Clean Feed On for 12G SDI. THE 4.6K Film to Video LUT is also selected on the camera but Display 3D LUT is also Off. Zebras are identical.
This is the way to ensure the camera and the BMVA12G7 are independently calculating their respective Zebras based on the clean feed.
The UM4.6K LCD has Zebras On and Clean Feed Off so I can see the camera Zebras. For the Front SDI going to the BMVA, I can have Clean Feed On (or Off and all other camera options Off), so I’m using the BMVA to generate Zebras and they look the same as the camera LCD Zebras and the BMVA12G7 Zebras. Same sensitivity to changes in my iris.
I was surprised to see False Colour variations on the BMVA12G7 which is peculiar because the Zebras are consistent. Sometimes I want to see False Colour while shooting outdoor events under changing light conditions; I have used the camera LCD or the BMVA with False Colour (to maintain pink and green skin) a few times that way but I’ll use the BMVA12G7 Zebras for clipping while the larger and brighter image is good for framing and focus.
It’s been a learning experience going through these options and it also reminded me what a capable camera the UM4.6K is while I’ve mostly shot with the BMPCC4K in the last year. So glad the older camera is functioning very well for the ways I use it: 4608x1920 and 3840x2160 with the 1.33x-65 Anamorphot for client shoots. Only option I have to record CinemaDNG lossless or ProRes 444 XQ for special occasions. Knock on magnesium (but gently, eh?).
To do the tests today and have both cameras feeding HDMI and SDI into the BMVA12G7 and monitor either camera with one button to select the HDMI or SDI feed is nice. I’m thinking if the music festival happens this year I could use both cameras for different angles and monitor both via the single BMVA12G7 since SDI can run a good distance. Let the UM4.6K and my assistant capture more of the stage and shoot with the BMPCC4K to handle the performers’ closeups.
