As much to say I was here...
VF is VF, the 'F' bit says it's a kite flying comp, so it's about flying kites, and for the entrants, hopefully as well as you can, (which ever way that is).
A necessary part of the comp is submitting an entry which is in video form, the 'V' bit...
Video is part of it and it is a skill in it's own right.
To have a valid entry you need to be on the way with these 2 skills (V and F), both of which we aren't born with and which need to be learned, so to the learning we go, and when we are there enough with both we are rewarded with an opportunity to be in the running.
If you get to this point you get a chance to have a valid entry, and being there are juicy prizes to be had, then fitting into the rules is fair and reasonable.
Here's my hard and fast rule... If at any point I freeze a video and there's no kite in it then there is no kite flying going on and is
in the voting as a crime against kite control I
think there should always be a kite in the video
doing what you want it to be doing!
Just one mans opinion....
