I can't be the only one to have recently noticed a fair few gifs and clips surfacing on the web whereby elements (e.g. a character) have been cropped from one scene and pasted into a different scene, usually completely unrelated footage, for the lols. E.g. This is just the most recent I've come across, John Travolta with the Avengers: But many of them tend to just crop someone's head and paste it onto the neck of someone else in a different setting. Anyway, given how often I'm seeing them I'm guessing there's some relatively new software that's widely available that makes this pretty easily done. Anyone know what it is?
