Personalizing the interface of a smartphone is one of the most enjoyable ways to make a device truly your own. Owners of gadgets from Xiaomi, Redmi and POCO often want to go beyond static images and revive the lock screen or desktop. The standard functionality of the MIUI shell and the new HyperOS offers rich opportunities, but installing a full video as a background requires understanding the specifics of the system.
The process of implementing dynamic content depends on the operating system version and regional firmware. Global versions often have limitations that are not present in Chinese builds. However, there are proven methods and third-party solutions to circumvent these restrictions without obtaining superuser rights.
In this article, we'll take a look at all the available methods, evaluate their impact on autonomy, and tell you where to find quality source codes, and you'll learn how to safely customize live wallpaper without sacrificing the performance of the device.
Features of the work of live wallpaper in MIUI and HyperOS
Xiaomi’s shells have a complex graphical interface structure. Unlike pure Android, it has an aggressive energy-saving system that can prevent the video stream from being constantly rendered on the desktop. Standard factory-delivered “live wallpapers” are often optimized animations that consume fewer resources rather than full-fledged video.
When trying to install a third-party video, the system can force the playback process to stop if the wallpaper provider application does not have the appropriate permissions, a protective mechanism that prevents rapid battery discharge, and the user needs to manually configure exceptions for selected services.
⚠️ Attention: Use of high bitrate videos (4K, 60 FPS) on screens with a high refresh rate can lead to a noticeable reduction in battery life and heating the case in standby mode.
The key element here is the Theme that drives visual style. Some themes block the ability to install third-party video wallpapers by forcibly returning a static picture. Successful implementation often requires switching to a standard theme or theme with an open API.

The MIUI system prioritizes energy saving, so video wallpapers often require manual adjustment of the resolutions in the battery menu to work.
Video File Preparation: Formats and Optimization
Before you upload a file to the system, it must be properly prepared. Not every video format is correctly displayed as a desktop background. The most versatile and supported format is MP4 with H.264 codec. Using modern codecs like HEVC (H.265) can cause compatibility problems on older smartphones.
The resolution of the source file must strictly correspond to the resolution of the screen of your device or be multiples of it. If you stretch vertical video on the horizontal screen or vice versa, the system will apply crop (trimming), which can spoil the composition of the frame. Optimally use source with a resolution of 1080x2400 pixels for modern models.
- 🎬 Duration: It is recommended to use rollers lasting from 5 to 15 seconds. Longer videos will be repeated cyclically, which can be noticeable to the eye, and also take up more space in the cache.
- 📉 Bitrate: To save processor and battery resources, try to keep the bitrate of video within the limits 2-5 Mbit / s. Excessive detail on a small screen of a smartphone will simply not be noticeable.
- 🔋 Audio: The soundtrack in the wallpaper file is not played, it only takes up space.
For video conversion and cropping, it is convenient to use free tools on a PC, such as HandBrake or FFmpeg. If you work directly on a smartphone, applications like CapCut or InShot, where you can choose the minimum quality parameters when exporting.
Use of built-in functionality of Xiaomi Themes
The easiest and safest way to do this is to use a theme directory. Themes store has special categories with dynamic content. However, finding a specific video that you like is almost impossible, as the choice is limited to the library of partners.
However, this is a good way to find inspiration or actionable solutions, so to find them, open the Themes app, go to your profile and select Wallpaper, and there are often video screensavers that you can use on both the lock screen and the desktop.
The disadvantage of the method is that you can't upload your personal video from the gallery through the standard interface without "crutches." The system just doesn't see this option in the basic menu of choice of wallpapers for desktops. To download your content, you will need special tools, which will be discussed below.
Application of specialized application providers
For free video from the gallery, the best solution is specialized applications that act as live wallpaper, and the leader in this niche is the Video Live Wallpaper app, which is free, does not contain intrusive advertising and has a minimalist interface.
Once you install the application, the algorithm is simple: You run the program, select the "Select Video" option, and specify the desired file in the gallery, then zoom in (usually choose "Fill the screen") and, if necessary, sound (although it will not work on the desktop).
☑️ Installation algorithm through the application
It's important to set up the playback settings in the app correctly. If the video is slowing down, try lowering the quality in the wallpaper player settings itself or switching the rendering method. There's also an alternative application called intoLive that allows you to create live wallpaper from video and even convert it to a format that iOS understands, but it works steadily on Android as well.
⚠️ Attention: After installing video wallpapers through a third-party application, be sure to find it in the list of running processes and prevent the system from ending its work. 10-15 The background will become black or static again.
Configuring energy saving for stable operation
This is the most critical step that is often overlooked. Even if you install a video, MIUI will kill the process in a few minutes to save power. You need to manually create exceptions for an application that displays wallpaper (for example, Video Live Wallpaper or the Mi Theme system process).
Go to Settings → Applications → All Apps. Find your wallpaper app on the list. Go to Battery (or Energy Saving) and select Unlimited mode, which will allow the app to run in the background all the time.
You also need to stick the app to memory, open the menu of running apps (bottom-up swipe and retention), find the wallpaper settings window (if it's on the recent list), and pull it down to make the lock icon appear, which will prevent the process from being cleaned when you press the "Clear Memory" button.
| Setup parameter | Recommended value | Where to find out. |
|---|---|---|
| Battery mode | No restrictions. | Info about the application → Battery |
| Auto-start | Included. | Info about the application → Permissions |
| Displaying on top of others | Permitted. | Info about the application → Other permissions |
| Blocking ads | Disabled (for system) | Settings → Passwords and security |
Also check the general energy saving settings. If Ultra-Energy Saving or hard charge saving is on, the live wallpaper won't work. In these modes, the system shuts down all background processes, leaving only the basic call and message functionality.
Why does the wallpaper turn black after the reboot?
Alternative methods and widgets
There's another interesting way that doesn't require you to install separate wallpaper apps, and some widgets from GetApps or third-party sources can display video, and you can put this widget on the full desktop screen, creating the illusion of video wallpaper.
This method is less stable, because the widget can overlap with application icons, but it's more flexible to set up. You can have different videos on different desktop screens, using video-enabled "Photo Widget" widgets or custom widgets from theme developers.
Another option for advanced users is to use ADB-commands to force video to be installed in the system folder of live wallpaper. This method requires a computer connection and basic command line knowledge.
adb push my_video.mp4 /sdcard/MIUI/theme/.mi_theme_cache/video_wallpaper/However, after a system update or a theme change, these files can be deleted, so the method with the application providers remains the most reliable and simple for the average user, it does not require root rights and is saved even after the reboot, if configured correctly.
💡
For maximum smoothness of video wallpapers on AMOLED screens, turn on the option “Extended Colors” or “Vivid” in the display settings, but note that this will increase energy consumption.
Addressing common problems
Often, users are faced with the fact that the video is installed, but played in jerks, which indicates a lack of processing power or overheating, in which case it is worth reducing the resolution of the original file to 720p or reducing the number of frames per second to 30 FPS.
Another problem is the sound being desynchronized (if it is on the lock screen) or the sound being absent. As mentioned earlier, the desktop sound is not played normally. On the lock screen, the sound can only work in specific themes that support this functionality, and only if the theme settings include the "Unlock Sound" option.
- 📱 Black screen: Check the app's storage permissions. Without permission to read files, it won't be able to download video.
- 🔄 Cyclic reset: If the wallpaper is reset to standard after each reboot, check if the wallpaper application in Sleep mode is worth the battery settings.
- 🎨 Color distortion: Some video codecs may not display correctly. Try recoding the file into a format MP4 (H.264) color-profiled RGB or YUV.
⚠️ Note: Do not use video wallpaper if you have a Traffic Savings mode for mobile data, if the application tries to download content from the network.
In conclusion, installing video on wallpaper is a great way to personalize Xiaomi, and the key is to find a balance between beauty and performance. Use optimized files and properly configure resolutions to enjoy a dynamic interface without compromising the smartphone.
💡
The quality of video wallpapers depends not only on the resolution of the file, but also on the correct setting of exceptions in the MIUI energy saving system.
