What is the function of the Rolling Edit tool in video editing?

The Rolling Edit tool is designed to adjust the timing of adjacent clips on the timeline without altering their overall duration. When you use the Rolling Edit tool, it modifies the Out point of the first clip and the In point of the adjacent clip simultaneously. This allows you to maintain the overall length of the sequence while shifting the cut point between these two clips, giving you precise control over the flow of video content. This functionality is essential for fine-tuning transitions and ensuring a smooth narrative progression in your video projects.

The other options focus on different aspects of video editing; for instance, adding clips to a sequence, adjusting audio levels, and changing frame rates are important tasks, but they do not pertain to the specific function of the Rolling Edit tool.
