What do the terms 'in point' and 'out point' refer to?

The terms 'in point' and 'out point' specifically refer to the precise start and end times of a sequence or clip within a video editing context. An 'in point' marks the location where you want the playback to begin, while the 'out point' marks where the playback should stop. This allows editors to define and control the specific portion of the footage that will be used in the final edit or composition. Mastering these concepts is essential for efficient editing as they help in accurately trimming clips and managing timelines in video editing software. Understanding how to set and utilize in and out points can significantly affect the pacing and flow of a video project.
