Here is my 2 cents - I have been editing and producing video since the 80's. A lot has changed since then.
My #1 rule is to put yourself in your audience's mind. Show them something they will enjoy (not what you enjoy) and remember that you make entirely types of editing decisions for youtube, family, commercial client, or nature video for sale.
#2 tell a story. Endless minutes of a drone flying over a lighthouse goes from thrilling to boring in a few seconds. In commercial TV, movies, etc. the trend is to have a "payoff" every few seconds, (payoff = surprise, dazling footage, unique footage etc.) To do this you will need a LOT of raw footage to edit from. You can't just go out and film 30 minutes and make a 20 minute video, guaranteed boredom.
#3 Sound. Our phantoms do not capture ambient sound. To make a high quality video the viewer needs to hear believable sound. Not some overpowering acid rock or other music with no real sound. I use a digital recorder at ground level and let a little of the phantom sound in but other wise just what ever is natural for the scene.
#4 I also agree that most of the phantom footage is shot Too High. Think about it. A forest of trees, you can shoot it from 400 feet high or just over the tree tops. It keeps the viewer looking for what's next when you see things passing by (puts them in the drone ). Some of the very most impressive phantom footage that I have gotten (based on viewers comments) was flying 3 feet over the surf at sunset.
#5 use the drone for what it does best - different perspective. Almost every other type of camera is next to someone's head giving an eye level perspective.
#6 similar to # 2 don't make each clip or scene too long. Don't overuse transitions. If you watch the best stuff on the National Geographic Channel, most changes are just simple cuts not some blurry star trek zoom.
Just my opinion
