I have some information on a fix for a problem that took me a while to figure out. I am hoping that it might be useful to others.
During my first series of P3 flights, I noticed that the videos were coming out dark. I didn't realize until months later that this was due to accidentally hitting buttons on the controller and changing the ev setting. I have learned that it is essential to check this setting before each flight! The P3 is a wonderful device, but it's unfortunate that a button that does something so important is located in a place where it's hard to avoid accidentally hitting it. I'm not sure which button it is, but it's on the front right side of the controller.
I wanted to salvage the dark videos as best as possible. I first tried Quicktime 7 on the Mac, which allows one to adjust brightness and contrast. This makes a dark video look great, but it doesn't allow one to save it with the changes. I found some software that does allow one to save such changes, but it introduces serious problems. I was able to nicely fix the videos by importing into iMovie 10.1.4, adjusting the brightness, and then outputting to 1080p. I first tried this approach by importing 1080p versions into iMovie, but this resulted in low quality output. I was able to get good results by importing 4K files directly into iMovie.
In cases in which I wanted to crop movies or combine more than one of them, I did so in Quicktime 7 prior to importing into iMovie. Quicktime 7 allows one to crop and combine movies, and the Pro version allows one to output the results. The processing with Quicktime 7 isn't very time consuming. For a movie of about ten minutes, the processing in iMovie took about a half hour on my Mac laptop.
