Camera field of view?
Correct framing is crucial for many missions. Not that some aspects can be corrected in post but getting it close while flying cuts the work load. Your Simulated Drone is nice and showing whether the horizon is in view is neat. But these are only as accurate as the assumptions made about the FOV both width AND height. The preview accuracy and subsequent mission footage being as expected, depend on the setting reflecting the actual camera FOV.
I for instance fly a Mavic2 which has several fields of view depending on whether it is video or photo,
Video has two: FOV 77% and HQ at 55% in 16:9.
Photo has two: 3:2 and 16:9.
Which of these is the assumption for the Mavic 2 Pro?
You have a Custom function that would allow me to pick one of the other 3 if I was smart enough to know what to change. If I ever figured the other three out it would be nice to be able to Name and Save that Custom setting. Even then a mixed fov mission would still be problematic to preview.
What was the stock assumption made?

This would be nice to see the Mavic 2 Pro with HQ. That's all I use since FOV has aliasing
We assumed full-sensor for each camera, which for the Mavic 2 Pro means 3:2. It is true you can select 16:9 aspect ratio and crop the frame, but the 3D preview does not reflect this with the Simulated Drone because it doesn't know what aspect ratio is in effect (the simulated drone is outside the mission plan in that sense). Theoretically we could detect it in the 3D view in the mission previewer (which is tied directly to the plan and would have the context). Would that be valuable to you? Do you use cropped aspect ratios often?
Jim,
I use HQ for all 95% of all filming. It gives the clearest results and it seems that many M2P users do also. I would imagine that more missions are flown with these types of apps for filming than are flown for photos so the choice to use the full sensor 3:2 seems odd.
4k HQ mode is not about aspect ratio. It has the same resolution as 4k FOV (Full Field of View) , but different FOV since it uses a different portion of the sensor chip as stated by Parkgt. I also use this 90% of the time. Would be great to have this in preview FOV setting and also video resolution setting.

Understood. As far as the camera commands go, is this resolution not already selectable?
No, only one 3840x2160 is in the list. No way to select HQ or FOV version. They are listed as separate entries in the resolution list in dji go 4 app.
M2P with HQ camera view is there now
Jim, can you double check the output going to google earth. It appears to me the HQ and FOV are the same view in google earth.
Google earth doesn't support setting a FOV because the window can be resized to any shape on your desktop. KML does have the ability to put a "photo overlay" inside the view, but it basically looks like a window frame floating in the air in one place:
