Crop video in CapCut desktop for TikTok, Reels and Shorts

You filmed a product demo sideways, and now TikTok, Instagram Reels and YouTube Shorts all want it standing up. A 9:16 crop throws away about two-thirds of the picture. Cropping is a frame edit that cuts the edges of the picture without changing the clip's length. We'd do this job on a computer rather than a phone, because a big preview makes a drifting subject easy to spot.

First we check that CapCut desktop is still available in the US, then sort out canvas ratio versus crop and the 9:16 crop steps. After that come how to reframe a moving subject, where captions and buttons belong, and the export settings each app accepts.

Is CapCut desktop still available in the US?

Before any cropping, it's fair to ask whether the app is still sold here, since its publisher is Bytedance Pte. Ltd. As of October 29, 2026, it is.

Apple's US App Store listing for CapCut shows version 19.9.0 and says it runs on a Mac with macOS 10.14 or later. The Google Play listing shows an update dated October 28, 2026.

For Windows, the build comes from CapCut's own site. Its desktop editor page lists Windows 7 or above, with Windows 10 recommended, and macOS 10.14 or above. Price is less clear. CapCut's Pro pricing help page states that cost varies by region, device and promotion, so read the plan screen inside the app. The crop guide calls the crop tool free with no watermark. That's CapCut's claim, and we didn't export from the app to check it.

Canvas ratio and crop do different jobs

Before any crop comes the canvas ratio, the shape of the whole project and the frame every clip sits inside. A crop decides which part of one clip shows in that frame. CapCut's crop guide for CapCut PC treats them as two settings. You crop the clip to 9:16. Setting the Ratio to 9:16 as well makes the preview match what TikTok shows.

Here's the usual mistake. Set the canvas to 9:16 but leave the wide clip uncropped, and it shrinks to fit the width with black above and below. In our test, a 1920 x 1080 clip in a 1080 x 1920 frame filled 31.7% of the height. The other 68.3% was black. The math is plain: 1,080 / 1,920 x 1,080 gives 607.5 rows of picture out of 1,920, and ffmpeg rounded that to 608. One more catch: our bars-only file and our cropped file were both exactly 1080 x 1920, so the dimensions alone won't tell you which you made. Only the preview will.

CapCut's guide also separates cropping from two tools that sound alike. Trimming cuts time from the start or end of a clip, while resizing scales the whole frame up or down without removing any of it. Cropping is the only one of the three that throws picture away, which makes it the setting to check twice.

If the clip is also headed for Stories, the 9:16 frame is the same. Our list of Instagram Story ideas has formats to fill it.

Crop a clip to 9:16 in CapCut desktop

So the order is canvas first, crop second. CapCut's guide and its crop video tool page describe these steps as of October 29, 2026:

1. Import the wide clip and drag it onto the timeline.
2. Set the project Ratio to 9:16 so the preview shows a vertical frame.
3. Select the clip, then click Crop in the toolbar above the timeline.
4. Choose 9:16 in the pop-up, or Free to draw the box by hand.
5. Drag the box onto your subject, rotate it if the shot is tilted, and click Confirm.
6. Play the clip through once before you export.

The pop-up also lists fixed shapes such as 3:4 and 1:1, and Free covers the rest. CapCut's guide suggests 1:1 or 4:5 for the Instagram feed and 16:9 for regular YouTube videos. A square post uses the 1:1 preset. The guide doesn't name 4:5 in the pop-up, so for a 4:5 post use Free and size the box by eye. At full height, a 1920 x 1080 clip keeps 607.5 pixels across for 9:16, 864 for 4:5 and 1,080 for a square. We'd cut the vertical version first, since it loses the most picture, and make the wider crops after.

The tool page adds a ratio lock for the crop box, covered in the questions below. CapCut sets no fixed limit on how far you can crop, but every pixel you trim is one the export must stretch back. Example: tighten a 9:16 box on a 1080p clip by 20% and it keeps 486 pixels across (607.5 x 0.8), stretched 2.22 times to reach 1,080.

If a menu name doesn't match your screen, check your version before anything else. CapCut's help page on updating CapCut PC puts the update button in the top-right corner and says the app checks for and installs the latest version itself. It warns that uninstalling during an update may cause loss of locally saved projects. Keep the app open on a stable connection until it's done.

Reframe a wide clip when the subject moves

A single crop box works when the subject stays put. Most clips don't. To see how much a fixed box loses, we built a test file with a dark square sliding 960 pixels across a 1920 x 1080 frame in 6 seconds. We cropped it to 9:16 two ways and exported both at 1080 x 1920. Our fixed crop from the center kept the square whole in 86 of 180 frames, cut it off in 57 and lost it completely in 37. The crop that moved with the square kept it whole in all 180. In a real clip, that's a viewer seeing your product the whole time versus an empty counter at the end.

CapCut offers two ways to make the moving version. Its crop guide pairs Crop with keyframes for pans that follow the subject: you set the box at one point, move along the timeline and move it again. Its Auto reframe page describes a switch in the Video panel that tracks the subject at the ratio you pick. It has settings for image stabilization and camera moving speed.

CapCut notes the feature is available in specific regions, so your copy may have Crop but no Auto reframe.

We'd try Auto reframe first where it shows up and fix its misses with keyframes. If the clip also runs on YouTube, our guide to reading the audience retention graph shows where people stopped watching. That's a fair check on whether the reframe held them.

What we tested

We didn't install or run CapCut. On October 29, 2026, we rebuilt the same crop math with ffmpeg 9.0.2 on a local Mac, and a Python script counted the square's pixels per frame. A frame counted as whole when 97% or more showed. The two crops:

ffmpeg -i source-16x9.mp4 -vf "crop=608:1080:656:0,scale=1080:1920" out-b-center-crop.mp4
ffmpeg -i source-16x9.mp4 -vf "crop=608:1080:'min(max(480+160*t-304,0),1312)':0,scale=1080:1920" out-c-follow-crop.mp4

Keep captions and buttons off the subject

Even with the subject in frame, the app's own layer can still cover it. Vertical feeds put the account name near the top and the caption and buttons along the bottom.

Meta's ad specs for Instagram Reels ask for at least 14% of the top, 35% of the bottom and 6% of each side to stay free of text and logos.

On a 1080 x 1920 export, those shares come to 268.8 pixels at the top, 672 at the bottom and 64.8 on each side. What's left is a box of about 950 x 979 pixels, close to a square and a little above the middle. Our test shows why the bottom number bites. The caption bar near the bottom of the wide source landed at rows 1,600 to 1,775 after the crop. Meta's bottom 35% starts at row 1,248.

So move burned-in captions up into the safe box, or add text after the crop so you can place it on the new frame. TikTok publishes its safe zones as downloadable files on its In-Feed ads specs page, but we didn't download them, so we can't give you TikTok's pixels. Our Facebook Stories size guide works through the same Meta percentages for story ads. Before you crop, scrub through the clip and note anything important that sits low in the frame, like a price card, a shirt logo or a pointing hand. Those are the details the bottom margin hides first.

Export settings for TikTok, Reels and Shorts

With the crop set, export is where each app's rules come in. Our three vertical test files came out at 1080 x 1920, H.264 with AAC audio at 30 frames per second. Here's what each platform's own page says, as of October 29, 2026:

One file can meet every limit in that table. Ours would be 9:16 at 1080 x 1920, H.264, 30 frames per second, between 3 seconds and 3 minutes long, and under 300 MB. That's our pick, not any one app's rule. The TikTok row is the ads spec, since TikTok's help page for regular uploads didn't load for us. The ads page also asks for a bitrate of at least 516 kbps. The Instagram row comes from Meta's Reels publishing specs, and YouTube's Shorts upload page sets the 3-minute cap. CapCut's crop guide puts its export ceiling at 4K and 60 frames per second.

Resolution is where the crop costs you. A 9:16 crop is as tall as the source and 9/16 of that height wide. That keeps 31.6% of any 16:9 clip's width (9/16 x 9/16 = 0.316). So a 1920 x 1080 clip keeps a 607.5 x 1080 slice, and exporting it at 1080 x 1920 stretches it 1.78 times. A 4K clip keeps 1215 x 2160, more than the export needs, which is why we'd film in 4K whenever a clip is headed for a vertical feed. A 720p clip fares worst: its 405-pixel slice gets stretched 2.67 times, against 1.33 times for the 810-pixel slice from 1440p.

Before you click Export, pick a cover frame. Our guide to thumbnail optimization covers what makes people tap one.

YouTube's Shorts help page caps a Short's title at 100 characters, so we'd put the product name in the first few words. For the description and tags, see how to rank videos on YouTube and Google.

If you're deciding whether a short clip should come before a written post, our comparison of video and blog posts sets out the trade.

Our take: set the canvas first, crop with a box that follows the subject, and keep words inside the safe box. Then export one 1080 x 1920 file for all three apps.

To hand off the editing, DigitalTreed's graphics and video service can take it on. Our editors charge for it, and one practice crop on your own footage will tell you whether you need them.
