Describe the 'Rate Stretch Tool'.

The 'Rate Stretch Tool' is specifically designed to adjust the speed of a clip by stretching or compressing it. When you use this tool, you can manipulate the duration of the clip to either slow it down or speed it up without altering the pitch or quality of the audio. This is particularly useful in video editing, where you may want to create a dramatic effect by extending a moment in time or to fit a clip into a specific duration.

By dragging the edge of the clip, you can visually change how long the clip plays and how it interacts with the surrounding clips on the timeline, allowing for seamless integration into your overall project. This functionality is key for editors looking to control the pacing of their story, whether creating tension with slow motion or enhancing energy with faster playback. Other tools listed in the options focus on different aspects of video editing, such as audio manipulation, motion graphics, or color correction, which do not pertain to the specific capability of changing clip speed through manipulation of its duration.
