Why not get creative and shoot some real video with I don't know "leaves moving or water or something". You can then fade this in where you think it should go. If you do enough of them and are happy with the quality then set up a website and sell them as backgrounds. If your real creative you never know this might make you some nice money for doing something for yourself and costs little to set up.

Same here
 

Especially live events.... I am amazed by live event production. Shot placement, etc. Probably because I have watched a lot of football lately. Those producers sure do earn their money.

An TV productions are increasingly grabbing my attention for the completely technical. I don't watch many movies, so I haven't had time to analyze those sorts of things lately.
