Unlike the relatively simple practice of audio tape looping that has been employed extensively in the music and art world since before the 1950s, magnetic video tape looping is allot more difficult. The main obstacles are maintaining tension, lengths involved and the way video is multiplexed with embedded sync signals and recorded on to the magnetic medium more often than not in a helical scan pattern. This means examples are few and far between.
A good place to start is
