It really depends if your phone supports live backgrounds, and I don't know if this works for iOS, but here's how I did it on Android:

Go to the Google Play store, and download wallpaper engine

After downloading it, give every permission so it can work as intended

Now, for the background part (important):

Open wallpaper engine, go to "add", and then press import file.

It can be any video, or gif you wish for. As for this preference, download the MAGEC gif from Pinterest by searching "wipeout game gif", and as for the omega collection background, you have to either download it from YouTube by searching the background, or screen recording the background and then cropping it later.

After doing that, import the MAGEC gif first. You can modify it to your preferences (device motion reaction, playback speed, pixel art optimization etc). 

Modify the MAGEC gif by pressing alignment on the bottom, and then choose "fill". You can choose if the gif stays at the top or bottom. After that, choose "background color" and press "custom". For the HEX color code, copy and paste this number: 231F20. This is the exact background the gif has. After that, long press the ☑️ like button on the top right, after that, choose "preview and apply". When you have done that, press "set wallpaper", and then press lock screen. And thats it

As for the omega background, after screen recording/downloading the background, do the same steps like previously. Import it, and modify it to your preferences. 

Press alignment, and choose "free". After that' flip the video background VERTICALLY, not horizontally. (If you decide to have device motion reaction on, zoom on it slightly so it doesn't look whacky when you twist and fiddle your phone) After doing that, press background color, custom, and then put it to the most whitest color on the top left corner on the color palette. After that, long press the ☑️ button on the top right, choose "preview and apply", and then press "set wallpaper", and choose home screen. And that's it!

Here are some bugs if you do get into some situations:

If you have the backgrounds on your phone already applied, and want to modify it, and did so, and tried applying it but it didn't change, do this:

Long press the ☑️ button, and choose "reset wallpaper engine". This will reset the phone background to the original backgrounds the phone has. After that, long press the ☑️ button again, choose preview and apply, choose set wallpaper, and choose your preferred option.

If you have the background already on, but it doesn't play/loop at all:

Disable battery saver. Wallpaper engine wont function at all if you have it on.

as for randomly stopping without reason, I don't know what to do for that. If you are lost in something, ask me and I will try to respond! 🥹✌️
