In Avid Media Composer, what does the "Timeline" represent?

The Timeline in Avid Media Composer is a critical workspace where clips are organized and arranged to construct a sequence. It visually represents the flow of the project, allowing editors to sequence video and audio clips in a way that determines the order of playback and the overall structure of the edited content. By placing clips on the Timeline, users can control timing, transitions between scenes, and the synchronization of audio and video elements. This functionality is essential in the editing process, facilitating an intuitive way to build narratives and manage complex projects.

The other options do not accurately depict the primary purpose of the Timeline. While it may also play a role in effects and audio adjustments, its main function is to serve as the foundational structure for assembling sequences, making arrangement the primary focus.
