*FREE* time lapse videos?

All,

I am looking for some FREE time lapse videos to put into a movie I am making.

Specifically I need a sunrise over a mountain scene - I found one on BBC HD gallery - yet they want like $170 or so for it - the one I like is 22 seconds, and I am speeding it up even...

if I do a google search and include the word 'Free' - then I get many hits for 'royalty free' sites for video - which is not what I am looking for.

thoughts on any free sites out there for movie content?

thx
