Ian, excellent video!
I still find the tripod mode helpful even flying at altitude.
If you look at a lot of video footage taken from land-based cameras (even films at the theater / on the TV), there is always movement. Often, that movement is small, not really changing the perspective / lighting of the subject (people talking} but is more interesting than a static tripod shot. I'm guessing that most people reading this knows what "dolly shot" means, and they're often done very slowly.
Before the Mavic, I used ATTI mode for slow movement -- just turn off GPS on a mild day and let the drone drift to add small movements.
Obviously, tripod doesn't work for long traveling sequences (covering a good distance of sea shore, or tracking a vehicle). Or if you want a nice sweeping shot with the POV racing over a field of grass / body of water at a low altitude.
But slow movement is useful too in many cases, not just close to bushes on the ground.
Ian, if you were to make a new video on this, I would like to suggest giving a more detailed difference between Tripod and Cinematic Mode. I too prefer to change the settings for smooth manual movement, but I like to understand the tools at hand in case they come in handy in a pinch.
I'll go out and figure the differences between the two intelligent flight modes myself, but it was the main reason I watched the video, so that last few seconds were a bit lacking for me.
