Modern smartphones Xiaomi, Redmi i Poco equipped with powerful displays and advanced multimedia capabilities that allow not only consuming content, but also creating it. One of the most requested features for bloggers, gamers, and educational creators is the ability to capture what's happening on the display. The standard shell MIUI or the new HyperOS provide built-in tools for this, but its correct configuration often raises questions among users.
The main difficulty faced by device owners lies in routing the audio stream. Screen recording without sound or with a quiet voice through An external microphone is a common problem that can be easily solved if you know the Android software architecture. Unlike competitors, the system Xiaomi allows you to flexibly manage sound sources, separating system audio and voice comments.
In this material we will analyze in detail the algorithm of actions for activating the function, adjusting quality parameters and resolving typical application conflicts. You will learn how to activate hidden codecs to increase the bitrate and what permissions are required for third-party apps to work stably in the background.
Activation of a standard screen voice recorder
To start working with the built-in tools, you do not need to install additional applications. The company Xiaomi has integrated image capture functionality directly into the quick settings panel. To access these options, you need to lower the notification shade by swiping down from the top and find the icon called “Screen Recording”. If you do not visually observe it, you will need to click on the pencil or the edit button in the corner of the panel and drag the desired element onto the active area.
After the first launch, the system will ask for the necessary permissions. Recording permission media files and access to the microphone are required. Without granting these rights, the application simply will not be able to save the resulting file or capture the audio stream. The app interface is minimalistic and contains basic control buttons: start, pause, stop and settings.
Before starting long-term recording, make sure that the Do Not Disturb mode is turned on so that incoming notifications do not overlap the content and do not interrupt the audio stream.
It is important to note that in some versions firmware MIUI the interface may differ slightly, but the operating logic remains the same. After activation, a floating control panel appears on the screen, which allows you to take a screenshot or enable drawing on top of the image at any time. This makes the content creation process more interactive and user-friendly.
- 📱 Open the control panel and find the “Screen Recording” icon.
- ⚙️ Click on the gear to go to the options menu before starting.
- 🎙️ Select the audio source: microphone or system audio.
- 🎬 Press the red button to start image capture.
Audio stream configuration: system audio and microphone
The most critical step of the setup is choosing the right audio source. In the recorder settings menu, which opens by clicking on the gear icon, there is a “Sound Source” item. Here the user is presented with three options: “Microphone”, “System sounds” and “Do not record”. The choice depends on the final goal of the video being created.
If you are recording gameplay or a tutorial on using an application where internal sounds are important (gunshots, music, system notifications), you need to select System sounds. In this mode, the device captures the digital audio stream directly, providing crystal clear quality without ambient noise. However, it is worth remembering that in some applications protected by copyright (for example, streaming services), system sound may be blocked.
⚠️ Attention: When you select the “System sounds” source, voice comments through the built-in microphone will not be recorded. To simultaneously record voice and game audio, you need to use third-party software or complex mixer settings, since a standard recorder Xiaomi often does not allow mixing two sources at the same time.
The “Microphone” mode is ideal for creating video comments or reactions. In this case, everything that happens around the phone is recorded. The quality of the recording directly depends on the noise reduction of your device and the silence in the room. It is recommended to use a headset for better separation of voice frequencies.
☑️ Adjusting the sound before recording
Adjusting the resolution and frame rate
The quality of the final video file is determined not only by the screen matrix, but also by the software encoding settings. In the recorder options menu you can find the “Video Settings” section. Here you have options to change the resolution and frame rate (FPS). The standard value for most modern smartphones Xiaomi is 1920×1080 pixels at 60 frames per second.
Increasing the frame rate to 60 FPS makes movement on the screen smoother, which is critical for recording dynamic games or scrolling through social media feeds. However, this also increases file size and CPU load. If you plan to upload videos to social networks, where the bitrate is compressed by the platform's algorithms, sometimes it makes more sense to choose 30 FPS to save space.
It is also worth paying attention to the orientation of the video. The automatic mode usually works well, but for specific tasks you can force it to landscape or portrait orientation. This will eliminate the need to rotate the video during editing. Codec Compression is usually selected automatically (H.264 or H.265), but in the advanced settings of some models you can find an option to select the bitrate.
| Parameter | Recommended value | Impact on file | Use |
|---|---|---|---|
| Resolution | 1920×1080 (FHD) | High | YouTube, standard videos |
| Frame rate | 60 FPS | Increases size | Gameplay, scrolling |
| Bitrate | 12-20 Mbit/s | Direct influence | Quality details |
| Codec | H.264 | Average | Maximum compatibility |
What is bitrate and how does it affect quality?
Bitrate is the amount of data processed per second. A high bitrate gives a clear picture without “squares” during sudden movements, but the file will weigh a lot. For a phone screen, it rarely makes sense to set values above 20 Mbit/s.
Using third-party recording applications
Built-in tools MIUI are good for basic tasks, but sometimes the functionality is not enough. For example, if you require simultaneous recording of system sound and voice, or you need more fine-tuning of the bitrate. In such cases, specialized applications from Google Playcome to the rescue, such as XRecorder, AZ Screen Recorder or Mobizen.
Installing third-party software requires careful attention to permissions. In addition to file and microphone access, such apps often ask for permission to “Overlay on top of other windows” and “Run in the background.” Without these rights, recording may be interrupted as soon as you minimize the application or the screen goes dark. Third-party recorders They often have built-in editors that allow you to immediately trim the video or add a watermark.
However, it is worth considering that free versions of such apps may contain advertising or limit the length of the recording. In addition, they can consume more battery resources than the native solution from Xiaomi. Before installation, carefully read reviews, especially regarding compatibility with your version of Android.
- 📥 Download a verified application (for example, XRecorder) from the official store.
- 🔐 Grant all requested permissions, including storage access.
- 🛡️ Allow work in the background in the Android battery settings.
- 🎚️ In the application settings, set the desired bitrate and format (MP4/MKV).
Problems with sound in specific applications
Users often encounter a situation where recording is in progress, but there is no sound in certain applications. This is especially true for instant messengers (WhatsApp, Telegram) and some banking applications. The reason lies in the Android security policy, which prohibits audio stream capture in applications that use encryption or VoIP protocols.
In the case of instant messengers, where sound is transmitted via an Internet channel, a standard recorder may not “hear” it. The only way out in this situation is to switch the source to “Microphone” and increase the speaker volume so that the sound physically enters the microphone. This will not give studio quality, but will allow you to preserve the audio component.
⚠️ Attention: Recording conversations in instant messengers and social networks without warning the interlocutor may violate the legislation on the protection of personal data and the secrecy of correspondence. Use the screen recording feature responsibly and only for personal or educational purposes.
Problems may also occur when playing protected content (DRM). When you try to record your screen while watching a movie on Netflix or an online movie theater, you may end up with a black picture with no sound or no signal at all. This is not a malfunction of the phone, but software protection of copyright holders.
If a particular application does not have system sound, try increasing the media volume and switching the recording source to “Microphone” - this is the only way to bypass software restrictions of DRM and VoIP.
Optimizing recording performance
Simultaneous rendering process graphics, video stream capture and audio encoding is resource intensive. On mid-range smartphones, this can cause a decrease in FPS in games or heating of the case. To minimize lags, it is recommended to close background applications before starting recording.
Particular attention should be paid to the “Game Turbo” mode, which is preinstalled on devices Xiaomi. Adding a game or heavy application to this mode allows you to allocate additional processor resources to it and limit background activity. You can also temporarily disable power saving for the recording process in the battery settings.
Don't forget about free space. High-definition videos fill up your memory quickly. A minute of recording in 1080p can take from 50 to 100 MB depending on the bitrate. Regularly clear the storage or use a memory card (if the model supports recording directly to SD, although more often recording goes to the internal memory).
Why can a video slow down during playback?
Slowdowns when playing a finished file are often associated with a lack of processor power to decode the selected codec or bitrate. Try lowering the resolution to 720p or the frame rate to 30 FPS. Also, the problem may be in the player itself - use VLC or MX Player with hardware acceleration.
Is it possible to record the screen in hidden mode?
It is impossible to record the screen without notifying the user (without a flashing icon or red dot) using standard Android tools. This is done for security purposes so that malware cannot steal data undetected. Any application that promises hidden recording most likely contains viruses.
Where are the recording files saved?
By default, all recordings are saved to a folder DCIM/ScreenRecorder or Pictures/ScreenRecorder in the internal memory of the device. You can find them through the standard Files explorer or in the gallery in a separate album.
