QuickTime Player is a free, lightweight media player that comes pre-installed on Mac. It’s perhaps best known as the default app when playing multimedia content on macOS devices. It supports many major file formats, including MP4, and offers the option of exporting a file in different qualities.
What it doesn’t offer is a crop tool. Historically, Apple offered a paid version of QuickTime called QuickTime Pro. This application cost around $30 and was essentially an upgraded version of QuickTime that was pre-installed on all Mac devices. Users with QuickTime Pro could crop videos, though the process required creating a custom mask in an image editor and then applying that mask to the video to crop it. However, Apple no longer supports QuickTime Pro.
As the use of a custom mask implies, cropping a video involves a reduction in what is included in the frame. The length of the video is unaffected by cropping. It’s the size of the frame of the video that is being changed. As an example, have you ever noticed how some videos have black bars on the top and bottom? That’s because the videos were either shot at or cropped to an aspect ratio that is wider than the screen you are watching them on. If you want your video footage to appear cinematic, you can crop the top and bottom out to create the same effect.
What if you’re happy with the framing of your video but want to crop the length? That is called trimming. Trimming a video does not affect the size of the frame. It involves cutting out unwanted parts of the footage at the beginning or the end. It’s easy to confuse this with cropping, as both usually involve cutting out unwanted content from your video. For example, you might have started recording your video before the action actually began or stopped recording a few seconds after the action ended. You don’t want your viewers to sit through seconds of preparation before the video actually starts. Fortunately, you can use QuickTime Player to trim out any unwanted sections of your video. The process is simple:
1. Open QuickTime Player. It should already be installed on your Mac. If it isn’t, you can download it from the Apple Mac App Store.
2. Import your video into QuickTime by clicking File in the top menu header, then selecting Open. Alternatively, you can locate the video in Finder and double-click to open it. QuickTime is usually the default application, meaning the video will automatically open in QuickTime. If QuickTime is not the default application, you can right-click the video file, select Open with, then choose QuickTime.
3. With your video successfully opened in QuickTime, it’s time to get trimming. Click Edit in the top menu header, then select Trim. This will open the trimming tool.
