I agree. The best videos I've seen are from Roger Taylor, and I love watching his story, but they could be much better. I'm not a video producer, but this is what I would like to see:
Single topic videos in a series. For example: Reefing. Mast position. Yard attachment point. Sail fabric. Mast construction. Sheeting. Batten types. Drift. Throat hauling parrel. Boat of the month. etc.
Keep 'em short, 1 - 5 min.
Follow a consistent format with a script or at least an outline prior to filming.
Some kind of professional production, include pre- and post- production. Edited. Subtitles. labels on screen. Title cards.
Lav/lapel mics, good cameras and lighting.
chosen & labeled screenshots & description for youtube
Sample Outline:
spoken Intro (<5 sec)
series title card (logo, theme audio) (~2 sec)
episode content (1-5 min)
Closing title: logo, more video links, subscribe link. Join JRA link (5 sec)
