Answer:
Nonlinear
Explanation:
In nonlinear editing, the term "inserts and overwrites" refers to the ability to add or replace segments of a video or audio timeline without affecting the entire sequence. "Inserts" allow you to add content at a specific point without moving existing material, while "overwrites" replace existing content at a chosen location. This contrasts with linear editing, where changes occur in a sequential and fixed order. Nonlinear editing provides flexibility in manipulating the timeline, enabling more dynamic and efficient content creation.
