Okay, here are the settings for Air 2S in 3:4 aspect ratio (set before flight in DJI Fly camera settings)

Here is how to install it:
OK thank you very much for this. I am still a little lost on how the camera starts to take photos. Do we have to manually do it or will it start taking photos automatically in the mission?
You set the camera mode to 3:4 Single Photo.
Mission Planner automatically calculates where it needs to take photos and it will automatically take photos, but you need to be in photo mode before you start the mission.
Guessing you could also do photogrammetry 3d scanning with different camera angles.
I have done that using my Parrot Anafi and Pix4D.
OK playing around with it this morning having my coffee. I made a simple mission on a tree farm near me. In mission planner it gives a time of about 30:45 and when I load it in Litchi Hub it shows 6 minutes. So which one is correct or what have I possible done wrong? 
This might be of some value to some people. It will Calculate the Ground Sampling Distance (GSD) and the image footprint on the ground by inputting values for the:
This is in Excel Format.
2 different flying speeds.
Make sure that the value in Mission Planner Survey Tool (Simple Tab) speed matches with the speed set in Litchi Settings (Mission Settings). If you want mission planner to use km/h or mp/h you can change that in mission planner settings tab.
Ah yes thanks. Not sure how I missed that setting in Mission Planner but I did.
Mission Planner was set to 5 Kph and Litchi Hub was set to 20Kph
Flew my first mission today. Uploading to Maps Made Easy to a free account. Will update this post when it is ready.
Here is a screen shot from running the photos through 3DF Zephyr.
Thanks for a great tool that Litchi is missing!
Maybe this can also be used for 3D modelling?
My 2 cents are to use gimbal at -45 and use cross grid for a starter.
Do you have an idea how to do this in a useful way?
There are many tools to create a 3D model from a group of photos.
If you mean how to program the mission then check the README tutorial on the GitHub page of this project but in Step 6 you need to uncheck the box that says “Camera top facing forward”, then in Advanced Settings tab (which you enable in the Simple tab) check the box that says Cross Grid, and continue following the tutorial.
Then in Litchi, before starting the mission set your camera to -45 before starting the mission, the camera should stay in the same position after you start the mission.
Thanks - that was exactly what I was looking for 
In my opinion, the specifications of the mini 2 camera are the same as the mavic mini 1. So you can refer to the following website.

this is my opinion.
I use a spreadsheet:
I would certainly welcome the ability to create a polygon of where I need the aircraft to fly, the height and overlap similar to what I can do with Autel Explorer. With Explorer I can create a flight plan in just a few minutes. The issue is that Explorer is nowhere as versatile as Litchi. At present with Litchi I have a spreadsheet that has the details for the various drones and their cameras and I enter a height and the required overlap. From this I manually create a grid with the various waypoints. It is somewhat time consuming but I have a number of master grids that on Litchi Hub I can just move to the location I need then save it with a new name.
What could be the case for the wrong fly-time??
As stated above this could be your problem.
“Make sure that the value in Mission Planner Survey Tool (Simple Tab) speed matches with the speed set in Litchi Settings (Mission Settings). If you want mission planner to use km/h or mp/h you can change that in mission planner settings tab.”
Thanks … but MissionPlaner kph and Litchi km/h… seams, this is not the problem.
