What is the function of a "timeline" in video editing software?

The function of a timeline in video editing software is to organize and sequence clips and effects. A timeline is essentially a visual representation of your video project where you can arrange video clips, audio tracks, transitions, and effects in a linear fashion. This structure allows editors to see how different elements come together over time, making it easier to align scenes, sync audio with video, and apply effects at precisely the right moments. As clips are placed along the timeline, editors can manipulate them by trimming, splitting, or extending their duration, enabling a seamless flow in the final product. This organization is crucial in creating a coherent and polished video that tells a story effectively.

In contrast, while displaying video in real-time, managing audio levels, and enhancing visual effects are important components of the editing process, they are functionalities that can be carried out within the context of the timeline but do not define its primary purpose. The timeline is fundamentally about the arrangement and sequencing of multimedia elements.
