What is the significance of setting in and out points in the Viewer?

Setting in and out points in the Viewer is essential for defining a specific segment of a clip that you want to edit. This allows you to isolate a portion of the footage that you find relevant or useful for your project. By marking these points, you can accurately select the exact start and end of the clip segment you want to work with, facilitating precise editing, trimming, or adding it to the timeline efficiently.

Establishing in and out points enables smoother workflows, especially when dealing with longer clips, as it focuses your editing efforts on just the required parts without having to manipulate the entire clip. This practice is crucial for maintaining a clean and organized timeline, ultimately leading to a more effective editing process.
