Brutal honesty is what I like best! I completely agree with you about the jerky parts. And yes, in an actual editing program I'd have pit transitions in place etc. I've edited quite a few drifting videos in the past. Just none of them from the sky.
The video was edited on my phone, within the DJI Go app. The shortest clip allowed is 6 seconds and they have no transition effects. So I did my best clipping the shaky parts out.
