What is the benefit of using the Rolling Edit tool?

The benefit of using the Rolling Edit tool lies in its ability to quickly fine-tune the edit point between two adjacent clips without affecting their overall duration in the timeline. When you adjust the edit point with this tool, it shifts the outgoing clip's endpoint while simultaneously adjusting the incoming clip's start point, maintaining the overall timing of the sequence. This functionality allows for seamless transitions and precise adjustments, making it an invaluable tool for editors who need to refine their edits without re-timing surrounding clips or disrupting the flow of the sequence.

In contrast, adjusting audio levels pertains to a different function and does not utilize the Rolling Edit tool specifically. Selecting and removing clips from the sequence pertains more to the Selection or Blade tool, while applying effects across multiple clips would typically involve using adjustment layers or copy-pasting effects rather than the Rolling Edit tool. Thus, the Rolling Edit tool serves a unique purpose that enhances the editing process by providing a straightforward way to refine transitions between clips.
