I've been using www.video.google.com to post video free on the Internet, but you have to wait days after posting for Google to review and accept the video before you can make it available. And then the viewer has to download the Google viewer to be able watch the video (and it's not available on the Mac). On the positive side, it is all set up for those wishing to charge per view.
There is an easier way if you are willing to put up with a few unobtrusive ads on the side. It's called PutFile.com and you can try it out here with a short documentary I shot at the Anti-Bush Anti-War Demonstration in downtown Denver on November 29, 2005.
