"Im not going to be using the actual videos but instead i'll be taking frame-grabs from these vids and using them as photos."

I don't know how cheaply u will get the videos. If u want good quality vcaps from video u should be working with uncompressed videos or very large files. I certain would not sell my uncompressed video cheaply unless I had agreement that it would only be used by you for vcaps without any other use permitted. On the other hand I could sell you actual vcaps at $.25 an image. Btw I am the frank that Patti was referring to.
