The Rate Stretch tool is designed specifically to change the duration of a clip by altering its playback speed. To make a clip that is 10 frames shorter fit into a specific, longer space, you would use the Rate Stretch tool to slow the clip down. This extends its duration to fill the gap precisely without affecting the In or Out points of adjacent clips or changing the overall duration of the sequence, thus meeting the problem's requirements.

A. Slip Tool: This tool changes the In and Out points of a clip within its existing duration on the timeline; it does not change the clip's length.

B. Slide Tool: This tool moves a clip's position on the timeline, trimming the adjacent clips to compensate, but does not alter the duration of the clip being moved.

C. Ripple Edit Tool: This tool trims a clip and shifts all subsequent clips, which fundamentally alters the total duration of the entire sequence.

"Trimming clips." This official guide details the function of each tool. For the Rate Stretch tool

it states

"The Rate Stretch tool speeds up or slows down the clip. It changes the duration of the clip

but it also changes the speed of the clip to fit the new duration." This directly addresses the scenario of making a clip fit a different-sized space.

2. Adobe Premiere Pro User Guide

"Trimming clips." The same document clarifies the other tools' functions

confirming they are incorrect. For the Slide tool

it notes

"The Slide tool moves a clip in time

while trimming adjacent clips to compensate for the move." For the Slip tool

it states

"The Slip tool simultaneously changes the In and Out points of a clip in a Timeline

while keeping the time span between them constant." For the Ripple Edit tool

it explains that it "affects the duration of the sequence."

"Premiere Pro CC 2018 - Advanced Editing." In the section on "Advanced Editing Tools

" the courseware describes the Rate Stretch Tool (R) as the method to "change the duration of a clip by changing its speed

" which is precisely the action needed to solve the problem.
