Aaron: I enjoyed your clip very much, especially the dog walkers and while I see what rfc said above but personally, I only see a hint of overexposure.
As you may have already learned, most
M2P owners shoot both video and stills in Manual mode so they have complete control over the exposure. Along those lines, if you don't have any Neutral Density filters yet, you might want to consider buying some as they are a Godsend when it comes to bright, sunny or even bright overcast lighting. To use manual during the day for video, set your ISO at 100, your shutter speed at twice your video frame rate, and then adjust your aperture. Many have found that f/4 is about the sharpest with leeway of maybe a stop on either side. So, if you set the mavic on a table before you fly and do the above only to find that you have to use f/8 or f/11 to get the exposure correct, then that's when you need to put an ND filter on the lens which will restrict some of the light and allow you to get back down to f/4.
BTW, having the histogram visible while doing all this is by far the best way to avoid poor exposures, at least IMHO. Personally, I hate "the zebras." If you're unfamiliar with histograms, I'm sure Mr. Google can school you right quick.
For Stills, things are a little different and, better in many ways than shooting video. You still want to expose properly for f/4 to optimize sharpness BUT, you don't have the 180 rule for video to get in the way, i.e., you can use whatever shutter speed that will give you proper exposure at f/4 while maintaining the ISO at 100.
PolarPro has an app that can calculate the proper ND filter to use on any given day which is quite handy and time saving. But, you don't have to be using PolarPro filters to use the app and it will work with any ND filters, at least as far as I know. So, again IMHO, ND filters are an absolute must for aerial photography/videography under bright conditions.
Anyway, it looks like you have a solid grasp on Power Director and in my amateur opinion, your clip was as good as I could have produced with Premiere Pro. I especially liked your text tweaks with strokes, gradients, and drop shadows. Me thinks you have a pretty darn good graphic eye.
BTW, where are you located? I ask because NTSC is for the States and PAL is for pretty much everywhere else.
Have fun and fly, fly, fly...
