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
First video-recording from a submarine successful video-recording of the inspection of Tenneco’s "Molly Brown" 32,500 barrel oil storage unit. Fred Hartdegen, Gulf Coast Operations Manager for Hydro Products, and James Smith, Hydro Products Field Operator, reconfigured a Sony two-inch, helical-scan video-recorder to fit through the hatch of the sub (video-recorders in the 1960s were a relatively new technology and were rather large) and used a “frequency stabilizer” from Cubic Corporation for the power supply. The “frequency stabilizer” converted the sub’s DC power (which varied significantly during maneuvering) to a stable DC which was then electronically converted by crystal oscillators into an AC sine wave with
