Thank you for this !
Some recommend to use 3:2 image size. Any values for this ratio ? @DE-CaTeR @pierotofy

2. Set correct image ratio. Go to the image menu, tap the second
   tab. Use the Image Ratio 3:2 value, it allows to use all square of
   camera’s matrix. Do not use 16:9 Ratio! Check another values
   of this menu – all defaults.

Additionnal info :

For example, DJI Mavic 2 Pro has the readout time of 62 milliseconds. If the drone moves at the speed of 10 m/s and at the altitude of 100 meters above the ground, the vertical distortion caused by the rolling shutter effect will be 23.88 pixels. The camera will shift to almost 57 cm during the image scanning time.

Hi Sorry the comment in the code is wrong. But the code is still fine - native 16:9 Image has 19.9 MP and 3:4 has 16.8MP
I uploaded the two testpictures.
