Mavic Air 2S 4K question

[bmoore1118]

I am trying to do some mastershots and some of the quick shots. I selected the 4K option to record these shots.

I am wondering what FPS these 4K videos are filmed in so I can set the shutter speed?

when you do a normal video you can select the FPS but when doing these shots it doesn’t give you that option.

I checked my footage.... the ones I have shot are 4K 30fps.
