You see the way it's jerking like that? Television video is made up of two fields, the top and bottom - these fields are interlaced to form one frame, or complete picture. When the video is broadcast, it's broadcast with the bottom field first, so that gets drawn and then the top field gets drawn. It's so quick that you see the entire image before it's redrawn with another image. If you present the top field first, you get jerkyness, because you're actually showing the "fraction of a second later" image first. Progressive scan video just removes the interlacing and you get the entire frame all at once, one image after the other, and you don't need to worry about which field you're presenting. Video presented on a modern digital system is all progressive, and the term has become meaningless. That video looks like someone encoded it for television and didn't do it right, quite probably with the hacked version of CinemaCraft Encoder that was on all the torrent networks some years ago.
