Which tool would you use to split a clip on the timeline?

The Razor Tool is specifically designed for cutting or splitting clips on the timeline in video editing software. When you select this tool, you can click on a clip at the point where you want to split it, effectively dividing it into two separate segments. This functionality is essential for tasks such as rearranging parts of a clip, removing unwanted sections, or creating transitions between different clips.

The other tools listed serve different purposes: the Track Select Tool is used for selecting multiple clips in a track, the Sync Lock Tool helps maintain synchronization of audio and video tracks during editing, and the Overwrite Tool is utilized for replacing existing clips in the timeline without affecting the overall structure. Understanding the specific functions of these tools is crucial for efficient video editing.
