But now how do you set the shutter speed if the original setting is 50fps and then you drop to 30fps? (I mean the 180 degree rule)
I've used 50 or 60 fps a few times and then slowed down some sequences, but I've never tried shooting at 60 and then generally going down to 30 fps.
These 'rules' are not set in stone. The shutter speed affects the amount of motion blurring per frame. A very low shutter speed would produce more blurring effect on the video and a very high shutter speed freezes the motion to the point where the apparent sharpness is higher and more 'crisp'. The more frames per second you have adds to the appearance of motion. A 1/30th on a 60 fps would appear a mess whereas 1/120th on a 30 fps would still be crisp. This is also why shooting 1/100th on 60 fps a 50 hz area with lights have less rolling of lights than staying on 1/120th.
If you predominantly fly slower but want a more pronounced motion blur you could shoot 1/60th on a 60 fps. Personally the reason why I dont like shooting at 30 fps is because of stuttering when you yaw because of missing images when you turn too fast. These lower frame rates require a much slower turn rate (like in film-making) known as 7 second rule.
I would just test the different shutter speeds on a fixed frame rate and see the effect, then move to the higher fps and test the same shutter speeds so you can compare the results and pick your preference.
Also, if your target fps is say 30 fps (youtube) then you should be using the double hence 60 fps or if 25 fps then 50 or 24 fps then 48.
