I like making and watching flying videos.
From a spectators point of view I have found that less is very often more.
Few opening shots and closing shots to make it more of a 'story'
I believe you can now get filters for these cameras which eliminate the prop effect
Speeding up the replay does allow you to show the whole journey - a normal speed replay of the most interesting bits is more captivating.
Am of course jealous of you flying in this gorgeous weather!
