"I have some videos that I have shot, now I need to crop into the subject and get rid of the unwanted parts around the subject, how do I crop the video in QuickTime?" As the pre-installed media player, QuickTime works well on Mac. In addition to video playback, it also offers several bonus features. Can you crop or resize a video with the built-in media player? This article will answer the question in detail.

Part 1: How to Crop a Video in QuickTime

It is right that you can find some useful tools in QuickTime, but the app is just a media player but not a video editor. With the free media player, you can trim a video and remove unwanted frames. When it comes to cropping video images, you cannot find any relative feature.

Does that mean you cannot crop a video in QuickTime Player? The answer is no. The Screen Recording feature in QuickTime can meet your need. You can decide the recording area and crop the video indirectly with QuickTime. Another problem is QuickTime cannot record the sound from your device. So, you have to get an emulating audio program, such as Sunflower.

Step 1

Firstly, you'd better copy and paste the video to your desktop screen. Make sure that you have installed Sunflower on your disk.

Step 2

Then run QuickTime Player, go to the File menu, and select New Screen Recording. Now, the Screen Recording dialog will pop up.

Step 3

Click the arrow icon and select Sunflower as the audio source. Set other options according to your situation.

Step 4

Open the target video on your screen, and click the Record button on the Screen Recording dialog. Then adjust the recording area box until it covers the subject you want to keep on the video.

Step 5

Hit the Start Recording button to begin cropping the video using QuickTime. When it is done, click the Stop icon on the top menu bar. Finally, go to the File menu, select Export, and follow the on-screen instructions to save the video.

Note: You must be patient and monitor the process since QuickTime cannot stop recording automatically. Moreover, it can only save the video in MOV format. If you cannot find Sunflower, you have to record the video with the microphone, which captures noise too.

Part 2: Best Alternative to QuickTime to Crop Videos

As you can see, QuickTime is not a good way to crop a video. Firstly, it is only working on Mac. Moreover, you can only crop a video using the screen recording feature. That is a waste of time if your video is very long. Plus, the video output format is very limited. It makes sense that so many people look for a QuickTime alternative to edit their videos. Blu-ray Master Video Converter Ultimate is just the tool that you need.
