Many MacBook users may come into the same problems mentioned above. As the built-in video player and screen recorder of MacBook and iMac, QuickTime can be counted as convenient and versatile. However, when it comes to its performance while recording Mac screen and the file size of the recorded videos it produces, QuickTime will lose its competitive edge.
Some Mac users complain that QuickTime will become choppy both when it is recording and playing videos. And it is common to find that the size of the recorded file can be way too big, like 1 GB for a 2-minute recording, which is hogging big chunks of disk space in his 128 GB MacBook Air.
But this doesn't mean you are out of luck. With the following methods, the QuickTime lagging issue will be fixed and QuickTime can create a smaller recording file for you.
In order to solve the lagging issue and the large file size of QuickTime recording, we will first demonstrate 2 feasible methods that you can easily make in the QuickTime settings. But it’s noted that as the default format of QuickTime recording, MOV, cannot be changed, you may need to compromise to lower quality when you avoid the lagging problem.
Here are the two methods you can refer to:
Other than making adjustments in QuickTime, there are also workable ways when you make use of some third-party apps. For example, you can try to replace QuickTime with a third-party recorder, so the recording will be more flexible. Or you can also use a video converter to help you compress the large-size QuickTime video and avoid quality loss.
Here are the details of the recommended methods and tools:
Changing display resolution on MacBook/iMac to lower resolution can somehow fix QuickTime lag and produce the recorded videos smaller in size. But notice that this may sacrifice a little visual quality.
- Double-click the gear icon (System Preferences) from the toolbar on the bottom.
- Click the menu icon on the top.
- Click the Displays on the window.
- Choose Resolution>>Scaled.
- Click a comparatively lower resolution.
Another way to reduce the file size of QuickTime recordings is by exporting the recording in medium quality after the recording is finished.
- On QuickTime, choose File >> Export As after finishing recording and you will get 4 options from the QuickTime Player menu bar: 1080p/720p/480p/Audio Only.
- Select a medium or low definition like 720p or 480p.
Note: users with the older version of QuickTime should adjust the video quality from the drop-down menu on the recording-control panel.
