Hey bro, I did a video for a school project back in year 9. i wasn't the best kitesurfer around, but i could manage some back-loops/spins and a few jumps. but tricks aren't everything. editing the video, like syncing it to music, using slow-motion shots at the right time and stuff helps make it a good video. i use Adobe Premier Elements to edit my vids. Now about the length of the video... people who don't kitesurf won't generally want to watch long videos so i would recommend doing 5 minutes of quality kitesurfing in a vid maximum. about the camera, we just use a normal Sony HQ video camera and mount it on a tripod for stability. I wouldnt get too keen for gopros and stuff like that because the footage might not be as good quality. here's a couple of my vids:
^^^(most recent one)
and
^^^(2 years ago, back in year 9...just realised how often i crashed lol)
This is just what i do. there is really no 'right' way with videos, it's whatever you feel is good. have fun man. hope this helped you out
