Great, so the process is pretty similar. I have to take out two SD cards (Fusion has one for each camera lens) and copy the contents to my laptop. I stitch the movies using their destop software (Fusion Studio), export 5K MP4 files. The export takes a long time and takes a ton on CPU -- my laptop becomes basically unresponsive for hours. Once that is done, I finish the montage in iMovie. For my amateur needs that seems to work well enough, but it is quite a long process...
BTW, for me the follow-this software feature would have been the biggest selling point for Rylo over Fusion. The way you can "pan" the view while it's following the subject looked very cool. I'll try filming with a longer pole, too.
