Hi, I'm looking for some stock atomic bomb blast footage, since I know there is quite a bit that is in the public domain, but I want to get it onto a 24p sequence and haven't been able to find any appropriate source footage, I know since that stuff is all film there must be some 24p version of it somewhere right?

Bottom left are download links to various different qualities.
