I actually stopped posting films for quite awhile unless it was to show a point or teach something specific. It's a fine line between an informational "here's an example of flying sucessfully", and "hey! look at how great I am!". I can mention your thought though.
Aside from the obvious tactical observations, one thing where films are invaluable is "seeing" the positions from the cockpit view and making a mental link between what you see and what that represents in a 3d environment. I "see" opponents flight paths seconds in advance. By that I mean I *know* where their best possible flight path will put them, and am actually maneuvering in anticipation of where they will be.
But that comes from experience. Where you may watch a film clip and think the situation was "cutting it close", I may see it as "by a mile". Films can help get an insight into the nuance of reading positioning by watching someones who has seen this same positioning a thousand times before and maneuvers accordingly.
I've recently axed my old site engine where I had brief write-ups posted with films, but the actual films are still
here if anyone's interested. The newer ones, are
indexed here, including the ones posted in this thread.
