Post-production
The show was recorded at NBC's Burbank facility using two-inch quadruplex videotape. Since computer-controlled online editing had not been invented at the time, post-production video editing of the montage was achieved by the error-prone method of visualizing the recorded track with ferrofluid and cutting it with a razor blade or guillotine cutter and splicing with video tape, in a manner similar to film editing. This had the incidental benefit of ensuring that the master tape would be preserved, since a spliced tape could not be recycled for further use. Laugh-In Editor Arthur Schneider won an Emmy Award in 1968 for his pioneering use of the "jump cut" – the unique editing style in which a sudden cut from one shot to another was made without a fade-out.
