Editing a video is essential for keeping viewers engaged. In today’s video‑rich world, trimming unwanted sections and tightening the narrative can dramatically improve watchability and retention.
Why Cutting Matters
Removing excess footage allows your video to start promptly, ensuring that the first ten seconds capture attention—critical for audience retention.
Using QuickTime to Edit
Apple’s QuickTime Player, launched in 1991, remains a reliable, cross‑platform tool for basic video editing. It supports cutting, splitting, and trimming directly within the player, making it ideal for users who prefer a straightforward interface.
1. Cutting / Splitting a Video
Splitting divides a clip into separate segments, enabling independent editing of each part. This is useful when you need to reorder scenes or remove specific sections.
- Open your video in QuickTime Player.
- From the menu bar, choose View > Show Clips.
- Drag the red marker to select the desired portion.
- Select Edit > Split Clip to separate the segment.

- A yellow rectangle will appear at the clip’s edges.
- Delete or rearrange segments as needed.
- Repeat until your timeline is organized.
- Click Done to finish editing.

2. Trimming a Video
Trimming removes footage from the beginning or end of a clip, keeping only the core content.
- Launch QuickTime and open your video.
- Select Edit > Trim (or press Command‑T).
- A yellow trimming bar appears around the clip.
- Drag the handles left or right to set start and end points.
- Click Trim and then File > Save to preserve changes.
