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

Their first home-grown VHS recorder - VR6560 - was virtually a clone of the VR2324, using the VHS format tapes and the usual VHS M-wrap.

Grundig also used U-wrap in its own VHS decks for a short while before using Panasonic-manufactured decks. Recorders in the format were manufactured by Philips and Grundig and
