Downloading my videos from Flickr

  I'm working on getting my Flickr pictures to flow to an S3 bucket via their API.
  It's all been working pretty well until I realized I needed to check on the videos, and see if I needed to do something special with them.
  Most of my Flickr uploads have been JPGs, but there are a few MP4s.
  Near as I can tell, there is no way to actually download the videos. I could of course be missing something.
  PS: It seems from this thread there was at one time a way to do it. Also on the Flickr developer blog.
