What tool should be utilized to move a clip's in and out points by the same amount simultaneously, ensuring the rest of the timeline is not affected?

The Slip Tool is the correct choice for moving a clip's in and out points simultaneously while ensuring no other clips in the timeline are affected. When using the Slip Tool, you can click on a clip in the timeline and drag it left or right. This action adjusts the in and out points of the clip, effectively changing what part of the source material is being shown, without altering the surrounding clips or their positions on the timeline.

The Ripple Edit tool, in contrast, adjusts the in or out point of a clip while shifting all subsequent clips to accommodate the change. This would not meet the requirement of keeping the rest of the timeline intact.

The Track Select tool is primarily designed for selecting multiple clips across a timeline track, which allows for moving a group if needed, but it doesn’t specifically function to adjust in and out points of an individual clip.

The Razor tool is used for cutting clips into segments, allowing for deleting or separating parts of a clip. It does not facilitate the adjustment of in and out points without affecting the overall timeline layout.

In summary, the Slip Tool allows you to adjust the content shown in a single clip while keeping everything else untouched, fulfilling the requirement outlined in the question.
