Change video ratio or resolution?

These two terms are a bit confusing and sometimes used interchangeably. Video resolution mainly refers to the quality of your video or how many pixels it contains. Video aspect ratio refers to the shape of your video (tall, landscape portrait). As an example you can have a square video or 1:1 video at any resolution, 720 by 720 or 1080 by 1080 are both square videos but at different qualities.

Why use Flixier to change the aspect ratio of a video

Vertical video maker

Vertical videos are all the rage these days thanks in big part to TikTok but also to Instagram stories. Our vertical or 9:16 video maker easily lets you create a video ready for these platforms, simply change the resolution of your project from the right side of the screen to 720:1280 or 1080:1920.

Square video maker 

Square videos were made popular by Instagram but Facebook uses them quite a lot on mobile too. With our square or 1:1 video maker all you need to do to make a square video is to set its resolution to 720 x 720 or 1080 x1080 in the project settings on the right side of the screen.

Landscape video maker

We covered the new and popular video ratios but let's not forget about the most important one. Landscape videos are still one of the most used video types around the world, they are used anywhere from YouTube to Facebook and the TV and Film industry. With Flixier you can definitely do them too.

Custom video ratio

Tall, square and landscape videos are of course the most popular video rations today but if you have special needs Flixier has a super handy custom resolution feature. With this feature you can simply type the resolution you need and your project will adjust to it instantly enabling you to create video at any ratio.

Crop videos

In case you just want to change the ratio of a video but not for your entire project you will simply need to click the Crop Video button on the right side of the screen with your video selected. Now drag the sliders to crop as much as you want on each side.

Make square videos with blur

When converting a tall video to a square one you’ll either need to crop into the video or endup with black bars. A more engaging way of doing things is to add a blurred version of the video as a background. To do that in Flixier simply duplicate the video on the timeline 2 times and use the Blur feature to blur the copies lower down on the timeline, you will also need to move them to the left and right and make them a bit bigger in the video canvas for a better effect.


I’ve been looking for a solution like Flixier for years. Now that my virtual team and I can edit projects together on the cloud with Flixier, it tripled my company’s video output! Super easy to use and unbelievably quick exports.

Steve Mastroianni -

My main criteria for an editor was that the interface is familiar and most importantly that the renders were in the cloud and super fast. Flixier more than delivered in both. I've now been using it daily to edit Facebook videos for my 1M follower page.

Evgeni Kogan

I'm so relieved I found Flixier. I have a YouTube channel with over 700k subscribers and Flixier allows me to collaborate seamlessly with my team, they can work from any device at any time plus, renders are cloud powered and super super fast on any computer.

How do I know my aspect ratio?

How do I know my aspect ratio?

To know your aspect ratio you will first need to know your video resolution. You can find this by right clicking your video and selecting Properties on windows or Get Info on Mac. Next use a tool like this one that will calculate your ratio based on your resolution.

Is 16x9 the same as 1920x1080?

How do I know my aspect ratio?

This is a very good question and the answer is both yes and no, let’s start with why they are different. In short they represent two different things, 16x9 represents video aspect ratio, in this case a landscape video and 1920x1080 represents resolution which defines how many pixels are in a video frame, the more pixels the better. For example you can have a 16x9 video that is 1280x720 in resolution. 

The terms are the same though if you are referring strictly to aspect ratio because 1920 by 1080 is actually a 16x9 ratio video.
