A/B Roll—A/B Roll is editing from a minimum of two sources:VCR’s or Camcorders and recording to a third VCR. This technique has need of a Video Mixer and/ or Edit Controller to provide smooth transitions between the sources. The sources also needs to be electronically “Sync’d” together, that way the record signals are consistent.

What Are the Types of Video Editing?
There are two general types of video editing – linear editing and non-linear editing. Linear editing employs the use of video cassette recorders, camcorders, Edit Controllers, Titlers and Mixers in order to edit. These processes are basically mechanical in nature.
This type of editing, the steps proceed in one line from start to finish, taking one cut at a time.
In non-linear editing, new technology has greatly influenced its popularity over linear editing. This type uses the computer environment to enhance editing. It employs no mechanical function but is almost entirely digital in nature. The most popular method of non-linear editing is a visual cut-and-paste method. The two types of video editing may also be combined.
