I have really been enjoying this App. I'm a UAV (drone) enthusiast, and when I purchased my DJI Phantom 4 about one year ago, I had no idea that I had an interest in video editing.
Up until recently, my video editing platform was a fairly vintage, Windows 7 laptop using Windows Movie Maker, and although I was able to work with most of my footage to make a somewhat watchable video, it took forever to load the files into the program and then save the finished product in the end.
So recently, I purchased a 10.5" iPad Pro upon which I loaded LumaFusion, and what a world of difference. Even 4K videos - if I choose to film in that resolution - are not at all an issue.
I am still very much of a novice at video editing, and my UAV flying skills are not perfect but improving. This summer, one of the things that has really helped to improve my flying skills has been several opportunities to film the kids wake boarding behind the dinghy. This provides a fairly fast moving and dynamic subject to film, and the more time I spent working at it, the better the footage became.
Anyway, here is a short video of just that.
