Video manipulation have been instances when this technology was used during political campaigns. The proof-of-principle software "Face2Face" was developed at Stanford University. Such advanced video manipulation must be ranked alongside and beyond previous examples of deep fakes. The concept of manipulating video can be traced back as far as the 1950s, when the 2 inch Quadruplex tape used in videotape recorders would be manually cut and spliced. After being coated with ferrofluid, the two ends of tape that were to be joined were painted with a mixture of iron filings and carbon tetrachloride, a toxic and carcinogenic compound to make the tracks
TiVo digital video recorders They have coax/RF, composite/RCA, and S-Video output, and the DVD systems also have component out. Audio is RCA stereo, and the DVD systems also have digital optical out. Some TiVo systems are integrated with DirecTV receivers. These "DirecTiVo" recorders record the incoming satellite MPEG-2 digital stream directly to the hard disk without conversion. Because of this, and the fact that they have two tuners, DirecTiVos are able to record two programs at once. In addition, the lack of digital conversion allows recorded video to be of the same quality as live video. DirecTiVos have no MPEG encoder chip, and can
