Video: Actor Robert Pattinson “shapeshifting” during interview

Actor Robert Pattinson While it is amusing to take at face value, the actor‘s face isn’t really doing this, of course. The unintentional morphing alien effect is the result of compression errors with the data stream. This is one of the most interesting distortions I’ve seen, and it is happening to an actor who plays the part of a supernatural being (vampire) in the movie he is discussing.

The compression software used in this video reduces the amount if data transmitted by guessing what, in the next frame, a certain pixel will be based on what it was in the previous frame. This introduces successive errors and the image degrades from the original, until a key frame is transmitted and the real image is again restored.

When motion prediction is used, as in MPEG-1, MPEG-2 or MPEG-4, compression artifacts tend to remain on several generations of decompressed frames, and move with the optic flow of the image, leading to a peculiar effect, part way between a painting effect and “grime” that moves with objects in the scene.

Whats the purpose of this?
Some bad after the fact vixeo editing?
“Morph this image into this image‚Äú software has been around for over a decade, and this is a particularly bad utilization of that.
Did u make this one or something?:s

Can’t tell if joking, but this is just some simple masked filtering done on the video (contrast/edge enhancement).

Yeah, compression entities like that can be pretty freaky. Another video that I saw a long time ago comes to mind:

I have a vague memory of seeing this video in an article on this blog, but I’m not sure.
