Insert and Overwrite Editing

When putting the pieces of film together the editor had two choices: either a

piece of film was added to the shots already cut together, and therefore the

overall length of the Sequence was increased, or a piece of film was placed

into the Sequence and a corresponding amount of film, the same in length,

removed – thus the overall duration did not change. These two choices are

what Insert and Overwrite Editing are all about.
