Extend Photo/Video Backdrop To Get Better Visual Assets

Under most circumstances, changing the video/photo aspect ratio always means the loss of a portion of the background. Even if you decided to zoom out to keep all backgrounds, you might end up with having a default black background which doesn’t agree with your visual assets.

We understand how much eager you are to extend the backdrop of your photo and video naturally. Now, follow us to extend photo and video background with a powerful photo and video editor, or generative AI.

2 AI Image Background Extenders

There are tons of photo background extenders out there, thanks to the development of AI. Nearly all image extend tools can identify the object around the border and complete filling tasks instantly.

After countless trials, we now recommend two AI image extenders which work perfectly in terms of generation quality, as well as generation speed. They are Adobe PhotoShop, and FlexClip.

Extend Photo Background with Adobe PhotoShop

Adobe PhotoShop, integrated with Generative AI, can identify the items on your photo borders and automatically fill the background. What's better, you are able to use simple prompts to decorate the background. For instance, you can add an artwork to the empty wall, or add plants near the table. Go from imagination to creation at Adobe PhotoShop in a matter of clicks!

Step 1. Increase Canvas Size

Launch Adobe PhotoShop Beta, and then drag and drop your photo to it. Click on the Crop tool, hold Shift and Option on Mac, or Shift and Alt on windows, and drag the lines to increase canvas size. Click on the check mark to confirm the changes.

Step 2. Fill the Empty Background with AI

All you need to do is grabbing a cup of coffee and wait for a satisfying result.

2 AI Video Background Extenders

Currently, there is no such a thing called AI video background extender. The technology hasn't reached this far to fill the background with corresponding elements and animate them. To extend video background, we will need the extended background and a little bit of editing skills.

Extend Video Background with Premiere Pro - Video Tutorial

Step 1. Create an Extended Video Background

Adobe Premiere Pro is not like Adobe PhotoShop where you can extend video background and incorporate the background into the video. You can only make video edits with this software. So if you've decided to stick to Adobe Premiere Pro, the first thing is taking a screenshot of the first frame of the video, and then utilize Adobe PhotoShop or FlexClip.

Step 2. Export the Background & the Video

After successfully getting the extended background, drag and drop the video to the timeline, with the extended background image on the top layer.

Step 3. Use the Mask Tool

Click on the background image. Head over to Effect Controls > Mask. Manually outline the main parts of the video, and check the box of Invert, which is the last option under the Mask. You have now perfectly merged the video and the extended background.
