I must say, I think, that the tenor of 'KabirT's post is pretty intimidating. Perhaps it wasn't intended to be so, but there seems to be a dirty great banner associated with it which says 'No Videos Here'.
As a videographer who doesn't take stills at all I'm a little confused. I post my vidoes on YouTube, they are generally of light aviation/air displays/steam railways and are put up on YouTube simply to share, ie they are in the same spirit as the enthusiasts who put their stills up on one of the stills sites that are available.
Please could the moderation team offer clarification as to their intentions and the criteria by which they would judge videos.
