Guys, take it from someone who has done this for over 6 years now. Supply and demand does not apply to stock footage.
The more videos there are out there of a specific event, the less like they are to pick yours to use. 5-10 years ago if you had great video of an event, you were one of a half dozen or less that did. Because of that fact, often they wanted your video and they wanted a LOT of it. Yes, today they'll still want your video if its fantastic, but odds are, they aren't going to buy as much because 10 other people will have similar shots.
