How can you trim clips in the Timeline?

Trimming clips in the Timeline is effectively accomplished by dragging the edges of the clips. This method allows for precise adjustments to the in and out points of a clip, providing a straightforward and intuitive way to refine the length and timing of your footage. When you hover over the edge of a clip in the Timeline, the cursor changes to indicate that you can click and drag to shorten or lengthen the clip. This action instantly updates the Timeline, ensuring that your edits achieve the desired pacing without needing to switch tools or access additional menus.

While cutting with the Razor tool is a valid technique for splitting clips into separate segments, it does not serve the purpose of trimming the length of a single clip directly. Adding transitions impacts the visual flow between clips but does not alter their duration. Additionally, adjusting audio mixer settings pertains to audio levels and mixing, rather than the physical editing of visual clips in the Timeline. By focusing on the edges of the clips, you gain direct control over the clip's duration in an efficient manner.
