I would like to use Mavic Pro footage in Adobe After Effects 3D. Has anyone done this and if so can they point me to where I can learn how to get the data from a flight and if there are any tools for importing it into After Effects?

I don't know if you can import the flight data, that would be cool. But After Effects can do 3D mapping from any footage

I'm aware of that, however  camera tracking in AE doesn't work very well over heavily wooded areas. And can be very time consuming for clips of any length. I'm sure that data is available, because I see third party apps using it to render 3D models, but I don't see anywhere in the DJI app where that data can be captured without resorting to their API.
