What the subject wants to ask is how to make the video into a screensaver for Apple mobile phones.

1. First, save the video you want to be a screensaver as a dynamic wallpaper.

2. After the video is saved, we enter the phone settings page and change the wallpaper.

When we choose a screensaver, we choose a real-time photo album.

4. In the live photo album, find the previously saved video, and then set it as wallpaper to complete the operation.
