Head pasting is an editing technique that involves using cutout faces of individual people or characters, and superimposing them on existing footage in sync with another character's head movements. The phrase was coined by mfaizsyahmi, although the technique has been used for a long time, such as in America's Funniest Home Videos (AFV) where the host's head Tom Bergeron are superimposed on submitted home videos.
The most noticeable characteristics of headpastes is the usually disproportionate size of the superimposed head in comparison with the body. The pasted head could have a different lighting and shadow than the rest of the video, and if not done correctly, would not sync perfectly with the rest of the body, resulting in the head 'drifting' away from the body erratically. Owing to the fact that the pasted head are merely images, it does not turn smoothly, and the mouths don't usually move when the character speaks.
Use by Untergangers
Despite being seemingly crude and hastily-made, it is a common practice among FX-based Untergangers who would like to depict characters such as Hitler better than what the original Downfall footage can offer. Headpastes can be done using Sony Vegas (via the Track Motion and/or Event Pan/Crop tools), Adobe After Effects and Adobe Premiere. It can also be done in other editing suites like VideoPad, albeit at a limited extent.
KakashiBallZ and Vzorkic are some of the notable Untergangers to have popularized the use of the technique, with several others making use of it in conjunction with more advanced effects such as rotoscoping and CGI.
Templates for headpasting are usually done by isolating the head from the rest of the image with a green colour fill, in order to be used with Sony Vegas' Chroma Key tool. This, however, is prone to artifacts, especially when the image used has colour tones that are close to the chroma key colour. An alternative technique used by some Untergangers like Staedty86 and Subtitlecomedy involves cutting the unwanted parts of the image off, usually with Adobe Photoshop, GIMP or Paint.NET, and saving the head template as a transparent .PNG image.
