I’ve always filmed at 30fps NTSC also in the belief that the quicker frame rate will lead to smoother pans but I think that shutter speed also contributes to that.
I’ve had a few flights with the Air now and I firmly believe that it films and photographs better than the Pro, the bitrate is one factor but there’s a whole lot more to it, newer tech, have a look at this: Image Quality Deep Dive - Mavic Pro vs Air - Part 1 - YouTube
I did the FCC Go4 mod last week and I know this is no real test but at 3,800ft out, there was no sign of any signal or video loss, she was rock solid. This video won’t win any prizes, it’s just to try to show the quality, as I say on there, any mush you see is there courtesy of Youtube, the original is clean as a whistle.: https://youtu.be/4PkcCc4zufE
So my Pro is now (very sadly) up for sale…
