In this tutorial, you'll learn how to resize a video quickly with Clipchamp. First, import your media, then resize your video, and lastly, export it. It's that simple.

How to change the dimensions of an existing video

When you create a new video, the default aspect ratio will be 16:9. But if you want to change the dimensions later or copy your video in another aspect ratio, you can do that too. 

See below for a step-by-step guide, as well as tips on removing black bars and borders if you want your videos to fill the frame.

NOTE: if you want to create a new version of a video with different dimensions while still keeping the old version, first make a copy of the video on the editor homepage, then open the copy and follow the below steps.

Step 1. Click on the 16:9 aspect ratio button

To change the aspect ratio of your entire video, click on the 16:9 aspect ratio button located under the export button.

Step 2. Preview available aspect ratios

9:16, 1:1, 4:5, 2:3, and 21:9 aspect ratio options will appear. Hover your cursor over each aspect ratio to preview which dimensions best suit your video.

Step 3. Click on your chosen aspect ratio

To select a new aspect ratio, click on your chosen ratio. We have decided to choose 9:16.

Step 4. Remove borders and black bars around your media

Black bars/borders will appear around your video if your media doesn't match the aspect ratio you have selected. This is called a letterboxing effect to preserve the full frame of your video.

To remove the black bars, click on your video in the timeline, so it's highlighted green. The floating toolbar will appear next to your video preview window. Click on the fill button.

Your video will automatically stretch/crop into the new aspect ratio.

If any unusual cropping appears, for example if your main visual isn't in the center of your video preview anymore, simply reposition your video. Click on the video preview, then slide the video around in the preview to create a new position.

You can also click on the fit button once you have clicked the fill button on the floating toolbar if you wish to keep the whole video without cropping.

There is currently no way to set all of your clips to 'fit' into the frame at the same time, so you have to set each individually. However, we're always working to improve the editor and plan to make this easier in the future.
