How to Crop a Video on Mac in the Easiest Way

We have to admit that there is no perfect native video cropper for Mac. iMovie is free and easy but has limited aspect ratio. FCP X is powerful but expensive.

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 it in real-time.

Open iMovie, and click the + icon in Projects to create a new project or open an existed one. Then load a video from a camera or a folder on your Mac after clicking the import icon.

Optional - Use Ken Burns in iMovie to Crop a Video on Mac

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.

If you want to undo any cropping, click Fit to restore the original video.

How to Crop a Video with 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 movies 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 (shorten a video) with the tutorial below.

Step 1. Open a video with QuickTime Player.

Go to "File" > and open a video on your Mac.

Step 2. Trim out the unwanted footage.

Go to "Edit" > "Trim". Then drag the yellow bar to trim redundant beginning or ending parts.

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.

Drawbacks of This Method

Obviously, it's a little complicated. And you should not have invested so much energy in such a simple feature. Moreover, Apple stops selling QuickTime Pro since 2017. It's only work for the installed users on Mac.

How to Crop a Video on Mac Using Final Cut Pro

Another video cropping software for Mac is Final Cut Pro X (now dropped the X in 10.5) which is more professional and ships with versatile and precise cropping tools. Even you crop a video exaggeratedly, you can fix the distortion in this professional video editor.

Launch FCP X, and click New Project to create a new project. Go to "File" > "Import" > "Media" to select a video to crop. Then drag the video to the timeline to crop.

Note: There are 3 different modes of crop in Final Cut Pro X on Mac.

  • Trim mode keeps the original aspect ratio, and it will auto add black borders to fit the project.
  • Crop expands the cropped clip to the entire frame. But you need to correct the distortion manually when the cropped clip obviously does not fit the frame.
  • Ken Burns is also available in Final Cut Pro X. you just need to set a start and an end frame, it will zoom in or out between these two clips like in iMovie.

Option 2. Enable the Smart Conform option.

Smart Conform is the newly-added feature since Final Cut Pro 10.4.9. It applies machine learning (accelerated by Apple Neural Engine on Mac computers with Apple silicon) to auto analyze and crop the dominant motion into vertical, square, or other size for social media platforms like Twitter, Facebook, and Instagram.

Right-click on the original project, and choose Duplicate Project As option which brings the setting windows. Choose vertical or square in the video format option. Check Smart Conform. Hit OK and wait for it to analyze timeline clips. Then you'll get a cropped video.

How to Crop a Video on Mac Using Photos App

Can I crop a video in the Photos app on Mac? In the previous version of Photos, you could only preview and trim videos. Now, Apple makes big updates in macOS Big Sur/Monterey (aka macOS 11/12). Editing capabilities of the Photos app are largely expanded, including cropping, filtering, and color adjusting powered by machine learning. If you know how to crop a video on iPhone using the Photos app, it is easy for you to do the same thing on Mac.

Step 1. Open your video in Photos.

Make sure that you have updated your Mac to Big Sur or Monterey. Then open one video in this app.

Step 2. Go to the video editing interface.

Click "Edit" on the right upper corner. Then you'll be navigated to the brand new video editing interface.

Step 3. Crop the video in Mac Photos.

Hit "Crop" on the upper side of the preview window. Choose an aspect ratio. You're allowed to reframe the video at both a freeform and a certain aspect ratio, including 1:1, 16:9, 7:5, 4:3, etc. Then drag each corner of the box to crop out a certain area.

Step 4. Save the video.

Hit the Done button on the upper right corner to save the cropped clip to your Mac.

Drawbacks of This Method

Photos with excellent cropping features is only available on Big Sur and later versions. However, if your Mac is too old to upgrade to Big Sur, for example, MacBook released in 2014 or earlier, MacBook Air released in 2012 or earlier, you have to turn to third-party video cropping software.

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.

Why does iMovie crop my video?

Because iMovie forces every video you imported to it to 16:9. If you don't want to lose any part of the frame, select "Fit" in the cropping style settings. But note that it will add black bars so to keep your video at 16:9 automatically.

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 some of them can crop the footage for you, iMovie and Photos for free use, and Final Cut Pro X for advanced cropping. As for QuickTime Player, I have to say, it is a good media viewer and video trimmer, but not video cropper on Mac.

To crop a video on your Mac quickly and intuitively, try VideoProc Converter. Another reason for its popularity among Mac users is its versatility. You can use it to edit videos simply, convert videos and audio files, download videos from 1000+ sites, record desktop screen, and rip DVDs. Now free download it to explore more features!
