How to resize videos for Instagram Stories and Reels

Step 1. Import videos or select stock footage

Resize any video for Instagram dimensions by uploading and changing the aspect ratio of your video in a few clicks. First, upload a video from your computer, connect your OneDrive, or use stock footage inside the content library. Then, drag and drop your video onto the editing timeline where your video will be set to the default 16:9 aspect ratio.

Next, click on the size button on the floating toolbar above the video preview inside the stage to access aspect ratio presets. Make sure no videos or assets are selected on the timeline for this step.

When you click on the size button, the aspect ratio presets will appear in a dropdown menu. To preview, hover your cursor over the 9:16 aspect ratio for Instagram Stories and Reels, or the 1:1 or 4:5 aspect ratios for feed posts. Click to apply when you’ve found the right Instagram preset. The following example will be resized for an Instagram Reel.

Step 3. Remove black borders and frames from videos

Sometimes resized videos will appear to have black borders and frames. This is due to the original video being a different size to the new Instagram aspect ratio preset. To remove these borders, click on the video on the timeline so it's highlighted, then click on the fill button on the floating toolbar inside the stage.
