Note: Crop in iMovie just changes the size and center of the frame. The aspect ratio of the cropped video is always at 16:9.

Optional 1. Crop Style - Ken Burns

iMovie features 3 cropping styles. Ken Burns is named after an American documentarian. It is an effect of panning and zooming. In Ken Burns mode, you need to crop out a start and an end frame, then it will zoom in or out between these two areas.

Step 4. Export and save the cropped video to your Mac.

Final Cut Pro X VS iMovie: Cropping Video on Mac

The most frequently used video editors on Mac are doubtlessly iMovie and Final Cut Pro X. There's no point in judging either iMovie or FCP X is better. After walking through the whole cropping process above, you must have an idea that they have different pros and cons in video cropping. Have a quick look at their brief comparison.

Compared with FCP X, iMovie is easier and fast to learn. It also has a mobile version on iOS devices so that you can crop videos right after shooting. If you are a video editing pro, you can enjoy more precise cropping and more editing features in Final Cut Pro X.

Even you are a skilled pro, cropping videos with fast changing frames is not that easy. Like say, crop out a skiing person in your video. The crop window has to be moving along with the person accordingly, so you have to crop video in iMovie or Final Cut Pro X frame by frame. But now new techs come up to solve it. Adobe announced the auto-reframe effect in 2019 to track along with the moving object and crop it at a certain aspect ratio automatically.

A free video editor from Digiarty is expected to be launched this year. This software will also ship with intelligent motion crop feature and relieves users from tedious cropping tasks. Videos you shoot for sports, kids, animals or any footage contains fast moving objects can be cropped out for sharing and editing in minutes. Just stay tuned and test it first once it launched.

How to Crop a Video in QuickTime Player

As the name suggested, it is a media player. But it can also record, edit and share audio/video files. Many Mac users are wondering whether they can crop a video in QuickTime Player or not. In fact, its editing features are limited to trimming and rotating. QuickTime cannot crop videos like iMovie or Final Cut Pro X. But you can crop QuickTime video length with the tutorial below.

Step 1. Open a video with QuickTime Player.

Go to File > Open a video file.

Step 2. Trim out the unwanted footage.

Go to Edit > Trim. Then drag the yellow bar to trim video length.

Step 3. Save the clip.

Navigate to File > Save to export the video clip.

Can't crop a video in QuickTime Player? Try QuickTime Pro.

All you have learned above is just trimming the video length. If you desire to get rid of the edges of a video, upgrade your QuickTime Player to QuickTime Pro, and install Photoshop on your Mac. By associating with a Photoshop mask, it achieves cropping a video with the following steps.

Step 1. Create a JEPG image of the video.
Take an image from the video that you want to crop a video in QuickTime Pro on your Mac. And export it as an Image Sequence in .jpg format.

Step 2. Create a Mask in Photoshop for your QuickTime video.
Open Photoshop. Go to Edit > Copy, and paste the image to Photoshop. Select the area that you want to keep by the Photoshop Rectangular Marquee tool, and fill it with black. And then invert to the rest area and fill it with white as a mask. Then save the file as a GIF or TIFF file.

Step 3. Apply the mask to the video in QuickTime Pro.

Step 4. Save the cropped video.
By applying the mask file, the extra area will be hidden. Finally, go to File > Export to output the cropped video on Mac.

I have to admit that it's a little complicated. And you don't need to invest too much energy in such a simple feature. Moreover, Apple stops selling QuickTime Pro since 2017. It's only workable for users who have already installed it on Mac.

But don't be upset, because there are many free alternatives to QuickTime Pro, like say VideoProc. With an intuitive cropping UI, you can easily drag and resize the crop window to remove annoying edges or redundant parts in your video at any aspect ratio and preview in real-time.

FAQ about cropping video on Mac

How do I crop a square/vertical video using iMovie?

Let's make it clear at first that iMovie can't make any square or vertical video. But here are some tricks on what you can crop square/vertical videos on your Mac for Instagram and Facebook.

1. Export the edited video from iMovie, then import it to Keynote (requires macOS 10.14 or later).

2. Navigate to Document > Slide Size, and customize the size, e.g. 1080 x 1080 for a square video, 607 x 1080 for a vertical video. Drag the video to adjust the position and reframe it.

3. Then change the background color in Format > Background. You can also add texts and graphics (.png) if you have a background for your video.

4. Go to File > Export to QuickTime, finish the export settings to get the square/vertical video on Mac.

How do you crop multiple clips in Final Cut Pro X?

It's a hassle to crop video clips one by one. FCP X has a lifesaving setting to apply the crop to multiple clips selectively. First, crop one of these clips, and press Command+C and right-click on the clip. Next, go to Edit > Paste Attributes > Tick Crop, then press Command and click on the clip that you want to paste the Crop. Done!

Can you crop a video in iPhoto?

iPhoto is a built-in app to organize videos and photos on Mac OS X exclusively. It is capable of trimming videos, but can't crop videos on Mac. What's more, it has been discontinued since 2015. Now iPhoto users have to migrate to Photos app on Mac.


In fact, among these Mac video cropping tools, only two of them can crop the footage for you, iMovie for free use, and Final Cut Pro X for advanced cropping. As for Photos and QuickTime Player, I have to say, they are good media viewers and trimmers, but not video croppers on Mac.

Our free non-linear video cropping software released this summer will be surely easy and professional for motion crops. Please stay tuned. Before that, you can try VideoProc to pre-experience fast and intuitive video cropping on your Mac.
