Hello fellow pilot!
Only one major thing needs fixing. I am surprised noone else commented on it. (I had the same problems with
this film)
The horizon needs to be horizontal if you are flying level. With loads of solid equipment to put your camera mount on, I am sure you can figure out a way to do this.
I film PG and PPG. The paraglider is far harder to film since there is nothing rigid to attach a camera mount to. Powered paragliding is easier to film since there is a rigid frame.
Top class bit of filming though, interesting angles.
