How to Use Your Own Video as a Live Wallpaper on Mac

You have a clip you actually like. A drone shot from a trip, a slow loop you made, a few seconds of something you captured. You go to put it on your desktop and macOS has no place to put it. System Settings, then Wallpaper, offers Apple's dynamic desktop pictures and aerial videos, and that catalogue is Apple's. There is no Add File button.

So the answer is a third party app, and the rest of this is the practical part: which file types actually work, the two ways to get one in, where the file ends up afterwards, and how to cut a clip so it reads as a desktop rather than as a video playing on a desktop. That last part is the one most people skip, and it is the difference between a wallpaper you keep and one you turn off in a day.

What macOS gives you on its own

Worth knowing before you pay for anything. Open System Settings, then Wallpaper, and Apple's dynamic desktop pictures and aerial video wallpapers are already installed. They cost nothing, they are tuned for battery life, and several of them are genuinely beautiful. The limitation is the one that brought you here: the catalogue is Apple's. You can choose from it, and you cannot add to it.

The file types that work

Vivid Walls takes these:

• Video: mp4, mov, m4v, webm
• Animation: gif
• Stills: png, jpg, jpeg, heic, webp

One note on webm: it is converted once as it comes in, so the import takes a little longer for that format and nothing else changes afterwards. If you get to choose, an H.264 or HEVC mp4 or mov is the smoothest path, and it is what a phone, a camera and most screen recorders already produce.

Stills are in that list for a reason that is easy to miss. A still image set as a wallpaper is not interesting on its own, but a heic or a png gives you a way to mix your own photographs into the same library and the same per display setup as the moving ones.

Two ways to get the file in

Both routes do exactly the same thing, so use whichever is in front of you:

1. File, then Import Wallpapers. A standard macOS file chooser opens. You can select several files at once.
2. Drag the file onto the app window. Drop it anywhere on the library grid.

Either way the clip appears in your library with a thumbnail taken from the video itself, its resolution, and its length, so a library of twenty clips is still readable at a glance.

The one thing that catches people: folders

Both routes take files, not folders. If you drag a folder of clips onto the window, nothing is imported and nothing tells you why. The same applies to the file chooser, which will not let you select a folder as the thing to import.

The fix is simple once you know: open the folder, select the clips inside it, and import those. Worth saying plainly rather than leaving you to work it out from a screen where nothing happened. This is separate from importing a Wallpaper Engine library, which is a different menu item and does read whole folders.

Where the file goes, and why you can delete the original

Importing copies the file into the app's own storage, inside your user Library folder:

~/Library/Application Support/VividWalls/Wallpapers/

That copy is the one that runs. It matters in practice: you can rename the original, move it, delete it, or eject the external drive you imported it from, and the wallpaper keeps working. It also means a large library of your own clips takes disk space twice while both copies exist, so if you are importing forty gigabytes of footage, tidy the originals afterwards.

Cutting a clip that works as a wallpaper

A wallpaper is looked past, not looked at. That single idea decides most of the editing choices, and it is why a great video often makes a poor wallpaper.

• Make the loop meet. Playback is gapless, so there is no pause or black frame at the loop point. What you can still see is a cut, if the last frame does not lead back into the first. Trim to a moment where the motion is continuous, or find a section that starts and ends on the same composition.
• Keep it short. Ten to thirty seconds is plenty. A three minute clip is not more interesting on a desktop, it is just a larger file you rarely see the middle of.
• Match your display, do not exceed it. A 4K clip on a 4K display is worth it. A 4K clip on a 1080p laptop screen spends power decoding detail that is thrown away before it reaches your eyes.
• Prefer slow, continuous motion. Drifting clouds, rain, water, a slow pan. Hard cuts and fast camera moves pull your attention every time they come round, which is exactly what you do not want from a background.
• Leave the middle calm. Your icons, your windows and your menu bar sit on top of this. Busy detail in the center of the frame makes text harder to read all day.
• Assume it is silent. Wallpapers play muted by default, with a volume control if you want it. Design the clip so it works with no sound at all, because that is how you will watch it.

Per display, if you have more than one screen

Wallpapers are applied per display, so a two or three monitor desk can run a different clip on each, or the same clip everywhere. If you are setting up a multi monitor desk, the guide to running a different live wallpaper on each monitor goes through the arrangement in more detail.

What it costs in battery

Honestly: more than a still image. Decoding video is real work, and any app that tells you otherwise is not measuring. What makes it acceptable is that the work stops when nobody is looking. Playback pauses when a fullscreen app covers the desktop, when you pause it yourself, after an idle period, and on battery saver.

The practical version is that a wallpaper you cannot see is not costing you anything, and the numbers behind that are in the post on whether live wallpapers drain a MacBook battery.

The short version

macOS will not add your own video to its wallpaper list, so you need an app that will. Bring an mp4 or mov, import it with File then Import Wallpapers or by dragging it onto the window, and remember that it takes files rather than folders. The file is copied into the app's own storage, so the original is yours to move or delete. Trim so the end leads back into the beginning, keep it short and slow, and leave the middle of the frame quiet for your icons.

The same library also runs Wallpaper Engine scene files, 4K video, web and GIF wallpapers, so your own clips sit next to everything else rather than in a separate app. If you are still deciding, the free options for live wallpapers on Mac are worth reading first.

Common questions

Can I use my own video as a live wallpaper on a Mac?

Yes, with a third party app. macOS on its own only offers Apple's dynamic desktop pictures and aerial videos in System Settings, and there is no way to add your own file to that list. Vivid Walls imports your own mp4, mov, m4v or webm file and runs it as the desktop wallpaper, on one display or on each display separately.

Which video formats work as a Mac live wallpaper?

Vivid Walls accepts mp4, mov, m4v and webm for video, gif for animation, and png, jpg, jpeg, heic and webp for stills. A webm file is converted once on the way in. An H.264 or HEVC mp4 or mov is the least friction, because it is what a phone, a camera and most screen recorders already produce.

Do I have to keep the original video file after importing it?

No. Importing copies the file into the app's own storage inside your Library folder, so the wallpaper keeps working after you rename, move or delete the original, or eject the drive it came from.

Will my video loop without a visible jump?

Playback itself is gapless, so there is no pause or black frame at the loop point. Whether you see a jump depends on the clip: if the last frame does not lead back into the first, that cut is visible once per loop. Trimming so the beginning and end match is the single biggest difference between a clip that reads as a wallpaper and one that reads as a video.

Can each monitor run a different video?

Yes. Wallpapers are applied per display, so a three monitor desk can run three different clips, or the same clip on each.

Does a video wallpaper drain the battery?

It costs more than a still image, which is why the app pauses playback rather than letting it run unseen. Playback stops when a fullscreen app covers the desktop, when you pause it yourself, after an idle period, and on battery saver.
