Xiaomi’s current smartphones offer users an incredibly broad range of functionality that goes far beyond simple calls and correspondence. One of the most sought-after features in the MIUI and the new HyperOS arsenal is a built-in ekranoplan that allows you to capture what’s happening on the display, which can be required to create training videos, keep the game going at a difficult level or fix bugs in support applications.
However, many device owners have difficulty in capturing system sound or voice, and standard settings sometimes hide important options, while other devices simply don’t know where to look for an audio stream source switch, and understanding the nuances of this tool will allow you to create professional screencasts without installing third-party software.
In this article, we will take a closer look at all aspects of screen recording on Redmi, POCO and Xiaomi smartphones, learn how to activate hidden features, choose the right sound source, and avoid common mistakes that can leave video silent. We will look at both standard system tools and specialized applications for advanced users.
Activation and basic setup of the built-in recorder
Before you start recording directly, you need to make sure that the corresponding module is activated in the system. In the shells of MIUI and HyperOS, this tool is built in by default, but its shortcut can be hidden in the control panel. First, unlock the device and lower the "curtain" of the notifications by swipe from top to bottom.
If you don't see the Screen Record icon among the quick buttons, click on the edit icon (usually three dots or a pencil in the corner of the panel). In the list of available widgets, find Screen Record and drag it to the active zone, and then the feature will be available in one touch at any time you use your smartphone.
You click on the icon and you start the system recorder, and before you start recording, you'll see a small floating window with a timer and control buttons on the screen, and that's where the settings menu of this window (the gear icon) hides the key settings that you need to set up before you start.
☑️ Pre-recording checks
Importantly, the interface may vary slightly depending on the firmware version. On newer versions of Android (12, 13, 14), the system may request permission to display over other windows or access the microphone on its first run. Be sure to agree with all requests to avoid interrupting recording at the most inopportune time.
Sound source configuration: system audio and microphone
The most critical thing that beginners often miss is the choice of sound source. In the recorder settings, you'll find the item "Sound Source," which is the answer to the question of whether your video will sound the right way. The system offers two basic options, and understanding their differences is vital.
The first option is System Sounds, and when you choose this option, your smartphone will record all of your internal audio streams, whether it's music from the app, interface sounds, audio from video or games, and it's the perfect choice for creating tutorials or gameplay videos where it's important to be clean without extraneous noise.
The other option is Microphone, which will ignore the internal sound and record only what the external microphone hears, which is useful if you want to comment on what is happening on the screen in a voice or if the application you are recording blocks the capture of system audio due to DRM restrictions.
Why is there no sound in some applications?
There's also System Sounds and Microphone mode, which is available on some firmware versions, which allows you to write your internal sound and your voice at the same time, but be careful: if you use a Bluetooth headset, the system can switch to recording only from it or, conversely, turn off the external microphone, which will lead to silence in the video.
Configure video quality and coding parameters
The quality of the final file depends on the selected encoding parameters. In the recorder settings menu, find the "Quality" or "Resolution" section. Here you can choose a value from 480p to 1080p and even 2K if your Xiaomi screen allows. The higher the resolution, the greater the weight of the file and the higher the load on the processor.
The next important parameter is Frame Frequency (FPS), which is 30 frames per second for recording a static interface or reading documents, but 60 FPS is highly recommended to record dynamic games or animations, which will ensure smoothness of the picture, but will increase the file size by about one and a half times.
Also worth paying attention to the orientation of the video. By default, the recorder can try to guess the orientation or follow the turn of the screen. If you plan to upload the video to YouTube or TikTok, it is better to fix the desired orientation (horizontal or vertical) in the settings in advance to avoid black bars on the sides.
To save disk space, you can choose a compression codec. Modern Snapdragon and MediaTek processors used in Xiaomi effectively cope with the H.265 codec (HEVC), which provides better quality at a smaller file size compared to the old H.264 standard.
Use of third-party applications for advanced functions
Despite the functionality of the regular tool, sometimes a more subtle adjustment is required, which does not provide MIUI. In such cases, the help comes from Google Play. XRecorder is the market leader, AZ Screen Recorder and Screen Recorder - X.
The main advantage of third-party software is the ability to draw on the screen while recording, add a webcam (picture-in-picture) and adjust the bitrate of audio regardless of the video, which is especially true for bloggers who create content for Twitch or YouTube.
| Annex | Recording of internal sound | On-screen drawing | Advertising |
|---|---|---|---|
| Staff recorder | Yes. | No. | No. |
| XRecorder | Yes. | Yes. | There you are (in free version) |
| AZ Screen Recorder | Yes. | Yes. | There is. |
| Screen Recorder - X | Yes. | No. | Minimum. |
When installing a third-party app, be sure to check the permissions. It will need access to Show Over Other Windows and Record Audio. Without these rights, the program will either not start or write silent video. Also note that some heavy recorders can load the battery more than the system counterpart.
Optimizing performance during recording
Recording the screen, especially in high resolution and with sound, is a resource-intensive task: The smartphone processor has to simultaneously process the application graphics, encode the video stream and record the audio track, which can lead to heating of the case and a drop in the number of frames per second (FPS) in games.
To minimize the impact on performance, close the background applications before you start writing. Go to the running task menu and clear the memory, leaving only what you plan to write. This will free up RAM for the encoder buffer.
💡
Activate Do Not Disturb mode before recording so that an incoming call or notification does not interrupt the video or appear on top of the content.
If you're writing down a heavy one 3D-play, lower the graphics settings inside the game itself. 1080p 60 FPS It puts a load comparable to running another demanding app, and reducing the detail of textures or shadows in the game will help keep the video recording smooth.
Also watch the temperature of the device. If the smartphone overheats, the system will automatically lower the CPU frequency (trottling), which will lead to jerks in the video. Remove the case during long recording or use external cooling if you plan to shoot long videos.
Solution: Why no audio or video is interrupted
One of the most common problems is that the recording is ongoing, but there is no sound. If you have selected System Sounds but the audio is not recorded, check if this particular application blocks audio capture. Some banking applications or streaming services have copy protection.
In this case, the only solution is to switch to recording through the microphone. To improve quality in this mode, create silence in the room and bring the microphone closer to the dynamiku of the smartphone, or use a wired headset with a microphone if the recorder allows you to select it as the source.
⚠️ Attention: If the video is interrupted spontaneously, check the power saving settings. Super-saving mode or aggressive battery optimization can kill the recording process to maintain charge. Add the recorder to the exceptions.
Another problem is the lack of space. High-quality video takes up a lot of space. Make sure that the internal drive is at least free. 1-2 GB before the start of a long session. SD-The card in modern versions of Android is often unavailable or unstable due to the slow speed of writing memory cards.
💡
The stability of the recording directly depends on the free space and the absence of background processes that load the processor.
Editing and preserving the finished material
After recording, the file is automatically saved to the gallery, usually in the album «Screen_recorders» or "Screen Records." Shell. MIUI It offers a basic editor that's built right into the viewer of the photo. By clicking on the "Change" button, you can crop the video, delete the extra seconds at the beginning or end.
For more serious processing, it is better to use specialized applications such as CapCut or InShot. They allow you to overlay music, add text comments and transitions. Import the source from the gallery, process and export in the desired format.
Files are saved in format MP4, If you plan to edit it on your computer, you can transfer the file via Mi Drop (now Xiaomi Share) or via the Internet. USB-cable by selecting file transfer mode.
⚠️ Note: When transferring large video files wirelessly, make sure both devices are on the same 5GHz Wi-Fi network. At 2.4GHz, the transmission can take a very long time.
