I spent 3 hours looking at "FREE STOCK FOOTAGE" listings that were ..well .....not free.
Are you weren't looking at ROYALTY FREE stock footage listings? There's a difference.
"Free" means that you don't have to pay at all.
"Royalty free" means that you don't have to pay additional money for each "instance" of your work that uses the media (ie, you used it for a program, and that program is broadcast on television; you used it for a DVD and you sell copies; you put it on the internet, and you have X number of viewers a month). That doesn't preclude them from charging you a one-time fee.
There's tons of royalty free footage out there. You just have to pay a huge amount that one time. (For my taste, anyhow. I fully realize that the prices I'd balk at are perfectly acceptable to others. But then, they actually make money at this stuff; I don't. ;)
Utterly and completely free? No, there's not a whole lot. But there's some.
By the way digitaljuice.com has all three of their stock footage libraries on sale this week for just 169.00 each. That's a steal and some of the footage is really great.
