The Slide tool is useful for what purpose in editing?

The Slide tool is primarily designed to allow editors to shift a video clip's position within the timeline without altering its duration. By using this tool, you can move a clip left or right while keeping the in and out points intact, which ensures that the overall timing of the project remains consistent. This feature is particularly useful when you want to adjust the timing of clips in relation to other footage or audio elements, allowing for refined synchronization and flow in the edit.

In contrast, options like speeding up or slowing down clips relate to changing the playback speed, which is not the function of the Slide tool. Creating audio effects involves sound editing techniques rather than video manipulation, and trimming the edges of a clip is typically accomplished with the Trim tool instead. Thus, the Slide tool is uniquely focused on repositioning clips while preserving their duration within the timeline.
