Smartphones have long since ceased to be just a means of communication, becoming multimedia centers where every element of the interface is personalized. Owners of Xiaomi and Redmi devices often face the desire to replace the standard call melody with something more vivid and personal. The standard sound gallery, alas, is limited, and video response can radically change the perception of an incoming call.
The procedure for installing video calls on MIUI and the new HyperOS has its own features, which depend on the version of the shell and the region of the device. In this article, we will discuss in detail all the available methods, from using built-in functions to using specialized assistant applications, you will learn how to activate hidden system capabilities and avoid common errors when converting files.
Not all models support native video calling from the box without additional manipulation, but there is a proven algorithm to circumvent these limitations. We will look at the technical details of how codecs and formats work so that your video is played correctly and does not cause any interface malfunctions.
Video Files Requirements for Calls to Xiaomi
Before you start setting up, you need to make sure that the original media file meets the technical requirements of the Android operating system and the MIUI shell. The system strictly regulates the parameters of the incoming data stream, and violation of these norms will lead to the fact that the video will simply not install or will be played without sound.
The optimal format for video ringtones is MP4 with H.264 codec. This is the standard that ensures the best compatibility with the system components of the call. If you try to use rare codecs like HEVC (H.265) on older smartphones, the device may refuse to recognize the file as a valid source of video calls.
⚠️ Note: The duration of the video should not exceed 15-30 System constraints often cut files longer than this threshold, or the call simply won't have time to load until the caller responds.
The resolution of the original file is also critical. There's no point downloading heavy files. 4K video, because the screen of the smartphone has a physical limitation of pixels, and the processor will waste excess energy to decode the redundant data. 1080x1920 vertically.
An important aspect is having an audio track. Videorington without sound loses half of its functionality, so make sure you don't delete the audio stream when you convert. Some converters by default turn off the sound to save space, which in our case is a fatal mistake.
💡
Use free online converters or apps like Video to MP3 Converter to resize and compress the video to an acceptable size before installation.
Use of built-in features of the theme design
The easiest and most legal way to diversify the call screen is to use the official Themes store. In the MIUI shell, this tool is deeply integrated into the system and allows you to apply complex visual effects, including animation and video, without the need for root rights.
To get started, you need to open the Themes app on your desktop. In the bottom menu, select the Profile tab, then go to the Video Calls (or Video Ringtone) section, and here is a catalog of ready-made solutions that are optimized by Xiaomi developers to work with your particular smartphone model.
- 🎥 Open a video calling directory and search for keywords like “Nature” or “Cars".
- 📥 Click on your favorite preview file for preview and select Download button.
- ⚙️ After downloading, click Apply to install video on incoming calls.
However, this method has a significant drawback: you are limited to content provided by the store.To upload your own video through a standard theme interface is often impossible without the use of special plugins or third-party utilities.
If you want to use personal video content, you need to use the built-in theme tools, you need to use more advanced methods that allow you to import local files from the memory of the device, which takes a little more time, but gives you complete freedom of creativity.
Install video via Themes (Local Account)
There is a lesser-known way to upload your videos through the same theme interface, but using the import feature, which doesn’t work on all versions of MIUI, but it does bypass store restrictions on most current firmware.
First, prepare the video file and place it in the root of internal memory or in the MIUI/theme folder. Then launch the Themes app, go to the profile and find the menu button (usually three dots or a gear).
If direct video import is not available, you can use the renaming trick: Create a theme archive by embedding your video into it, and install it through the local themes menu, but this is technically complex and requires knowledge of the structure of the.mtz files.
⚠️ Warning: When working with local themes, always back up the system. An error in the structure of the theme file can lead to a cyclic interface reboot or bootloop".
A more reliable option for advanced users is to use third-party launchers or intermediary applications that emulate the system video call, which create a layer on top of a standard call, playing your video when a call arrives.
Why can't the video work?
Application of third-party applications for video calls
The most versatile solution, which works on almost all Redmi and Black Shark models, is the use of specialized applications from Google Play. the leader in this niche is the Video Ringtone for Calls application or its analogues, such as InShot (with the installation function for a call) or Any Video Ringtone.
The way these programs work is by creating a virtual layer on top of the lock screen and the call window, and when a call comes in, the app intercepts the event and starts playing the video file you selected instead of the static picture.
- 📲 Download the Video Ringtone app from the Play Market and install it.
- 🎬 Run the program and provide the requested permissions to access files and phone.
- 🎵 Select a video from the gallery, crop it if necessary and click Install.
It is important to configure permissions correctly. Android can block video display on top of other applications. You will need to find the application in the system settings along the Settings path → Applications → Application Management → [Your App] → Other permissions and allow the Display option on top of other applications.
| Parameter | Recommended value | Impact on work |
|---|---|---|
| File format | MP4 / 3GP | Ensure codec compatibility |
| Bitrate video | Up to 2,500 kbps | Reduces the load on the processor when calling |
| Permission | 720p or 1080p | Optimal clarity on the smartphone screen |
| Duration | 10-20 seconds | It can be loaded before you answer. |
Some users fear that third-party applications will consume battery power, and modern versions of such programs are optimized and activated only at the time of an incoming call, so their impact on autonomy is minimal.
☑️ Checking the application settings
Set up a video call for specific contacts
One of the most useful features is the ability to set up a unique video for each contact from the phone book, which allows you to instantly know who is calling you without even looking at the name of the subscriber, just from a characteristic video sequence.
You can do this through the standard Contacts or Phone app. Open the right person's card, click the edit button (usually a pencil icon) and find the Video Calls or Video Ringtone field. If the field is missing, your current theme or call doesn't support this feature natively.
If you use a third-party video calling app, you set up a customized video inside the assistant app itself, where you select a contact from a list and link a specific video file to it, and the logic is saved: when you call from that number, a dedicated video will start.
It is worth considering that if you have multiple applications for processing calls, there may be a conflict. The system will try to run the video through the "default" call application. Make sure that the default settings of the Application in the Phone section select the application that you use to manage video content.
💡
Individual video calls only work if the intermediary app has constant access to contacts and has not been closed by the memory cleanup system.
Solving problems with reproduction and sound
Often users are faced with a situation where the video is installed, but the call comes in silence or with a delay, this can be due to the aggressive MIUI energy saving policy, which kills the background processes necessary to start the video player at the time of the call.
To fix this, go to Settings → Battery and Performance. Find the app responsible for video calls (or system call if the setting is native) and select Unlimited mode, which will prevent the system from forcibly shutting down the process.
Another common problem is desynchronizing audio and video, which is treated by recoding the original file, and using a program on your PC or a powerful mobile app like Kinemaster to export the video again, making sure that the audio and video tracks are synchronized.
⚠️ Warning: If the phone starts to heat up during incoming calls after you set up a video call, turn it off immediately.This may indicate that the codec is incompatible with your processor's hardware decoder.
Also check the volume of the media. Video calls use the Media volume channel, not Ringtone. If you have the ringtone volume twisted to maximum and the media tracks to minimum, the call will come, but the video will be silent.
The impact of video calls on the autonomy of the smartphone
Using animated wallpaper and video to call inevitably leads to increased energy consumption. The screen is the most energy-intensive element of a smartphone, and its activation with a bright video stream requires resources.
However, since the video call only lasts a few seconds (until you pick up the phone or turn down the call), the overall effect on the battery per day is negligible.
To minimize the impact on the battery, it is recommended:
- 🔋 Use a video with a dark background (for the purpose of AMOLED The screens save energy).
- 📉 Do not install video 4K, unless there is an urgent need for it.
- 🚫 Disable the function in the mode "Ultra-energy saving".
Owners of older Xiaomi models may notice a faster discharge, in which case it is better to limit yourself to static live wallpaper or GIF-animations that are less demanding on processor resources.
