Which of the following is NOT a principal window of the Avid interface?

In the Avid interface, the primary windows play crucial roles in video editing, and understanding their functions is essential for efficient workflow. The Composer window is where video and audio clips are viewed and edited, allowing users to make adjustments to the sequence. The Timeline is where these clips are arranged in the order they will appear in the final output, giving editors control over the pacing and structure of the project. The Project window is where all media is organized, and various project settings are managed.

The term "Editor" does not represent a principal window in the Avid interface. Instead, it is often more of a general term that refers to the role of the person working within Avid or the overall functions of the software. Thus, it does not correspond to a specific window like the others do, which means it is not recognized as one of the principal windows necessary for the editing process. Understanding these core components helps users navigate Avid more effectively and maximize their editing capabilities.
