What distinguishes an 'in point' from an 'out point' in Premiere Pro?

An 'in point' marks the beginning of a segment of a media clip that you want to include in your timeline, while an 'out point' indicates where that segment ends. When you set an in point, you're specifying the precise frame or part of the clip where you want your sequence to start. Conversely, the out point defines the last frame you want to include in that particular segment. This distinction is crucial in video editing as it allows for precise control over which portions of a clip are incorporated into your project, making it easier to create seamless transitions and compile your footage effectively.
