Looking to crop a video in QuickTime on your Mac computer?

While it isn’t possible to crop a video using the basic version (the one that comes pre-installed on your Mac OS), the pro version of QuickTime player allows you to crop videos.

In this article, we’ll show you how to crop a video using QuickTime Pro with step-by-step instructions and pictures.

As a bonus, we’ll also show you how you can use Animaker to crop a video online using Safari or Chrome on your Mac computer.

Note that this article covers how to crop a video, which is about selecting the area of the video you want to use or highlight.

If you want to trim a video to your desired length, you can take a look at our article that provides step-by-step instructions on how to cut a video.

How to Crop a Video with QuickTime Pro

Like we said before, the QuickTime player that comes pre-installed cannot be used to crop a video. You’re going to have to upgrade it to pro for $30 in order to be able to crop a video. If you have QuickTime 7 installed on your Mac, you can go ahead and upgrade it to QuickTime Pro.

Also, you’re going to need Photoshop to create a mask file. Depending on how familiar you’re with Photoshop, creating a mask file in it could take several minutes. Once you have Photoshop installed on your Mac computer, follow the below steps to crop a video using QuickTime Pro:

Step 1: Capture a Frame of Your Video Clip

You’re going to need a mask file to instruct QuickTime on how it should crop your video. To create this mask file, you’ll first need a snapshot of a particular frame of the video. To copy the image of a frame using QuickTime Pro, open the video and go to Edit > Copy.

Step 2: Create a Mask using Photoshop

Open Photoshop and create a new project by going to File > New. Then, paste the image you’d previously copied. Now use the Rectangular Marquee Tool to select the area you want to use, and fill the selected area with black color. Now fill the space outside the black box with white color. Finally, save the file in GIF or TIFF format.
