Time to shoot? I have 3 batteries, flew all three twice so there was some lag time while they charged.
Time to edit? I watched each 15 minute clip (x6) a couple times and took notes on times where I wanted to snag shots. Then about another 2-3 hours laying it out, frame/color correcting/music.
Flying/filming is the easy part. The real skill is the editing and creativity in story telling (which I obviously need to work on).
Post your video when you do it, looking forward to it!
