Mavic Mini Map/Facade uses 16:9 aspect ratio instead of 4:3....
In Map or Facade components, I set my Camera to the Mavic Mini preset. Obviously I would like to capture maximum size images which is 4:3 (4000x3000), but when I run the missions my captured images are 16:9 (4000x2250). How can I correct this?
Maybe one workaround would be to use Camera:Custom and set the aspect ratio manually to 4000x3000. But I noticed that whatever image sizes I set, it doesn't affect the "Mission Estimate". This leads me to believe that this workaround will not give me accurate flight time, # of images, max speed, and Front Overlap because they are calculated based on a 4000x2250 16:9 image size.
I hope there is a simple solution without using this workaround and a guessing game.
Please Help

The map component always assumes full sensor (in this case 4:3). You just need to put a photo aspect ratio command before the map component.
Thank you Jim for a quick reply, and you are 100% correct. This does solve the problem I was having.
Why doesn't the Map/Facade do this automatically, but instead, at least for me, shoots in 16:9, until issued additional commands? Since the Mission Estimate is based on 4:3, it would make sense for it to do it automatically.
For other people who read this post and have encountered this problem with Map or Facade, here is the solution: You need to add 3 "New Component" with 3 Commands, above the Map/Facade. Your Components should be listed in this order:
1) Camera Stop Capture
2) Camera Mode: Photo
3) Camera Photo Aspect Ratio: 4:3
4) Map or Facade
If you don't do this, and your images get shot at 16:9, you will not be getting the Front/Vertical Overlap % you selected.
BTW, I tested Camera:Custom 4000x3000, and it still shot at 16:9 (4000x2250)... It seams that adding the additional commands is the only way to get a correct result.
Not all drones support all aspect ratios (16:9, 4:3, 3:2, etc), so this would have to be drone / camera specific, which makes it hard. Read this for more background.
You can also just change the aspect ratio manually in the user interface (commands are definitely preferred though).
