iPhones don’t let you use a video directly as a wallpaper. But you can turn the video into a Live Photo using an app called IntoLive.

Here’s how:

1. Download and open the IntoLive app from the App Store.

2. Tap on “Live Photo” or “Live Wallpaper” inside the app.

3. Choose the video you want to use from your gallery.

4. Tap Done at the top right corner.

5. Then tap the Export button (also top right) to save it.

6. Now open your Photos app.

7. Find the Live Photo you just created.

8. Tap the Share icon (bottom left corner).

9. Choose “Use as Wallpaper” from the list.

10. Make sure the Live Photo option (bottom center) is enabled.

11. Tap Set and choose Lock Screen or Both, depending on where you want it.

That’s it! Your video is now set as a live wallpaper.
