What are the differences between In and Out points in a timeline?

In Premiere Pro, In points and Out points serve specific roles in identifying segments of clips on the timeline. The In point marks the exact frame where a clip starts, allowing users to define the beginning of the sequence they want to work with. Conversely, the Out point indicates where the clip should end, thus denoting the last frame to include in the sequence. This functionality is crucial for editing, as it allows users to efficiently select and manipulate specific portions of video and audio clips, facilitating precise edits and transitions.

Other choices contain inaccuracies in their definitions of In and Out points. For instance, options discussing audio volume, video brightness, color correction, and clip quality do not accurately reflect the foundational functions of In and Out points, which strictly relate to the start and end markers within the timeline for clips. Understanding the correct use of these points is essential for effective video editing.
