Abstract
A resequencer changes the ABCD grouping of a sequence of video fields derived from a motion picture film via 3-2 pulldown so as to allow that sequence of video fields to be cut into or edited with a second sequence of similarly derived video fields, the cut or edit occurring at any desired position, without any artifacts. The resequencer comprises eight field stores. In each video field time, an input video field is stored into one field store and an output video field is read from a different field store. The particular field stores into which fields are read and written in each video field time are chosen so as to achieve the desired change in ABCD grouping.
