Step 1: Explaining Video Editing Operations:
Video editing tools (such as Canva Video Editor, Adobe Premiere, or OpenShot) rely on distinct spatial and temporal track modifications to manipulate clips:
Step 2: Analyzing the Core Terminology:
• Splitting (A): Slices a single video clip at a selected playhead timestamp to divide it into two or more distinct, separate segments.
• Cutting (B): Involves removing an entire interior section of a video clip (e.g., cutting out a mistake from the middle).
• Trimming (C): Specifically defines dragging the start (in-point) or end (out-point) handles of a clip to shave off or discard unwanted buffer frames at either extreme.
• Joining (D): Consolidates or merges multiple independent video sequences into a single continuous track.
Thus, the question's definition points directly to Trimming.
