The second option for video editing was to use two tape machines, one playing back the original tapes, and the other recording that playback. The original tapes were pre-rolled, manually cued to a few seconds prior to the start of a shot on the player, while the recorder was set to record. Each machine was rolled forward simultaneously, and a punch in recording, similar to punch in / out of early audio multitrack recordings was made at the appropriate moment. Beyond not being very precise, recorders of this era cost much more than a house, making this process an expensive use of the machines. This technique of re-recording from source to edit master came to be known as linear video editing.
