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.

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 Adobe PhotoShop
1. Even though Generative AI is cool, Adobe doesn’t guarantee that it can identify the background and extend it well. You might get some weird output, especially when your background is full of complicated items.
2. Generative AI is only on the latest version of Adobe PhotoShop beta. Update your software to access this feature.
Step 1. Choose a Desired Canvas Size
Launch Adobe PhotoShop. Click New File, choose a desired canvas height and width. You can even enter specific data. Confirm the change.

Enter PhotoShop Timeline Mode
Step 3. Do More Setups
When your video is successfully uploaded to Adobe PhotoShop, you have to click on the check mark above the canvas so that Adobe PhotoShop accepts your video.
Down below the canvas, there is a button showing either Create Video Timeline or Create Frame Animation. Make sure yours is in Create Video Timeline mode.

Step 4. Zoom Out Your Video
Zoom out your video a little bit by clicking Ctrl + C on Windows, or Command + Minus key on Mac.
Click on the Crop tool, there will be four lines around your video. Hold Shift and Option on Mac, or Shift and Alt on windows, and drag any of the lines to extend the video width and height.

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.

The Bottom Line
In a word, if you are extending a photo, go to FlexClip or Adobe PhotoShop, and then fill the background in just several clicks. When you need to extend videos with complicated backgrounds, you should take advantage of Adobe Premiere Pro.
