DJI Osmo Action 6 – How To Easily Crop Square Aspect Video In DJI Mimo App

Good day, folks. Shawn here from Air Photography. One of the most powerful new features on the DJI Osmo Action 6 is the ability to film in a perfectly square aspect ratio, and I want to show you exactly how to use it.

This feature solves a real problem for content creators. You might be uploading to YouTube one day and TikTok the next. Vertical content here, horizontal content there. Filming in square aspect lets you capture once and crop later for any platform you need.

The best part? You get to decide exactly where the crop happens. And DJI has built all the tools you need right into the DJI Mimo app. In fact, the app can do the cropping automatically while you transfer your footage.

How To Enable Square Aspect On The Osmo Action 6

If you are brand new to action cameras or editing, you might feel reluctant to use this feature because you are not sure how to crop it later. Trust me, it is simple.

First, power on your camera and launch the DJI Mimo app. It should prompt you to connect right away. Once connected, the app goes directly into the gallery and reads all the content stored on your memory card.

To set the square aspect, tap on the bottom of the screen to bring up your settings. Look for the icon in the middle where you can set your aspect ratio. By default, it is set to “default,” but we want to choose “custom.”

Now you are filming in a square aspect. You will notice crop marks in the corners by default. These help you line up shots for both horizontal and vertical framing, making it easier to visualize what the final crop will look like.

If the crop marks bother you, double tap the side button and they disappear. Just know that if you record with the crop marks enabled, they will actually be saved on the memory card with those blacked-out corners.

Batch Cropping: The Fastest Method

The fastest way to crop your footage is through batch import. Tap the icon at the top of the gallery to select multiple files.

Each video is labeled with its aspect ratio. You will see “1×1” next to your square footage. Select all the clips you want, and you will get an option asking what aspect you want to export them as.

Your choices are: original format (keeping the square), 9:16 for vertical, 16:9 for horizontal, 3:4, or 4:3.

If I tap 9:16, all my selected videos download automatically cropped to vertical format. No additional editing required. They are completely ready to upload directly to any platform that supports vertical content.

Need the same clips for YouTube? Go back in, select them again, choose 16:9, and the app exports them all automatically in horizontal format.

Manual Cropping: Full Creative Control

Batch cropping is fast, but manual cropping gives you something more valuable: you decide exactly where the crop happens.

Open one of your square aspect videos in the Mimo app. Tap on “aspect ratio” and you will see all the different options at the bottom: 16:9, 9:16, 4:3, 3:4, or keep it square.

Here is where it gets interesting. Once you select 16:9, you can drag to adjust exactly where the crop will be. Want more sky in your shot? Drag up. Want more of the waterfall? Drag down.

This is the real advantage of shooting in square aspect. Normally, when filming with an action camera in 16:9, the camera does the crop for you on camera. That works fine, but you do not get to decide where that crop happens.

For mountain biking footage, this flexibility is huge. You can choose whether you want more scenery out in front of you or more of the bike below you. That decision happens in post, not in the moment when you are focused on the trail.

Once you have the crop positioned exactly where you want it, tap the checkmark and manually export. The Mimo app also gives you access to all its other built-in editing tools while you are there, so you can make additional adjustments in the same workflow.

When Square Aspect Makes Sense

You may not want to film in square aspect all the time, but for certain scenarios it is incredibly handy.

If you are a content creator juggling multiple platforms, this is a game changer. One filming session can produce content for YouTube, Instagram Reels, TikTok, and Facebook without losing resolution or having to reshoot anything.

The Osmo Action 6’s new 1/1.1-inch square sensor was designed specifically for this workflow. Unlike previous generations where you had to physically rotate the camera to get vertical content, now it is all handled in software.
