Xiaomi’s modern smartphones have powerful multimedia capabilities that often require detailed demonstrations. Players, bloggers and users often face the need to capture what’s happening on the display along with audio. The built-in MIUI and HyperOS shell tools allow you to solve this problem without installing third-party software, but many options are hidden from the eyes of the beginner.
The process of creating a screencast on Xiaomi devices is significantly different from standard Android due to the deep customization of the system. The user may face a lack of sound in the final video or the inability to capture the internal audio track due to security limitations. Understanding these nuances is critical to getting a quality result the first time.
In this article, we will take a detailed look at all the available methods for capturing images and sound on Xiaomi, Redmi and POCO phones. You will learn how to activate hidden functions, adjust bitrates and avoid common errors that lead to “dumb” video or system failures.
Activation of the standard recorder in MIUI and HyperOS
The first step for any Xiaomi smartphone owner is to discover the built-in app. Unlike pure Android, where the feature can be scattered across panels, there is a separate system application in the shell from the Chinese manufacturer, and you can find it in the Tools folder or through a global search by the names Screen Recorder or Screen Recorder.
Once you start the app, you'll see the recording button interface and settings menu, and that's where the key parameters that affect the quality of the final file are, and the default default default configuration may not include audio capture, so manual adjustments are required before shooting.
You can use the control panel to quickly access the function. Swipe from top to bottom to open the notification curtain, and find the Screen Record icon. If the icon is missing, click on the edit button (usually three dots or a pencil) and drag the desired widget into the active zone, which will allow you to start the process in one touch.

For instant recording start, add the Screen Record widget to the floating window or set up the start by double tapping the back panel if your model supports it.
Audio settings: microphone and system sound
The hardest part about creating screencasts on Xiaomi is choosing the right sound source, so in the recorder settings (cog in the corner), you have to select "Sound Source." Here you have the options "Microphone", "Inner Sound" or "Do Not Record" available, depending on your final goal.
If you record gameplay where game sounds and voice chat are important, internal audio is the best choice, but some apps, such as Telegram or WhatsApp, may block audio capture for privacy reasons, in which case the system will automatically switch to silence or require the use of a microphone.
The microphone mode is useful for creating instructional videos with voice comments, in which case the phone will record all external noises, including your voice and notification sounds, the quality of recording in this mode depends on the sensitivity of the built-in microphone and environmental conditions.
- 🎤 Microphone: Records external sounds, is suitable for comments and video blogs.
- 🔊 Internal sound: Records audio from apps, ideal for games and music.
- 🔇 No Sound: Creates silent video, useful for quick interface demos.
The system can forcefully select one source while ignoring the second to avoid echoes and driver conflicts.
☑️ Checking the sound settings
Comparison table of sound sources
To make it easier for you to navigate your settings, we have prepared a comparison table that will help you understand which mode is best for your particular task and what limitations exist in each case.
| Parameter | Microphone | Inner sound | No sound. |
|---|---|---|---|
| Audio quality | Depends on the environment. | Digital, high-end. | Absent. |
| Vote recording | Yes. | No (only from the game) | No. |
| Background noise | Recorded. | Not recorded. | No. |
| Application locking | Rarely. | Often (banks, instant messengers) | No. |
When choosing a mode, always test a short snippet before a long record. This will save time and avoid reworking the material. The technical limitations of the Android operating system can vary from version to version, so verification is always relevant.
Solving problems with lack of sound
A common problem for users is when the video is recorded but the audio track is empty. First of all, check the permissions of the Screen Record application. Go to Settings → Apps → All Apps → Screen Record → Permissions. Make sure that access to the microphone is allowed if you use this mode.
⚠️ Note: Some applications (bank clients, secure video services) block screen and sound recording at the system level, in which case you will get a black screen or video without sound, and you can not get around this with standard methods.
Another reason for the silence is active Do Not Disturb mode with hard filters or conflict with another audio application. Close the background processes that play music and try restarting the recorder. Also make sure that the settings of the recorder itself do not tick the "No Sound" box by default.
If the problem persists only in certain games, check the Game Turbo settings. Sometimes noise reduction or voice priority functions in the chat can conflict with the system recorder by disabling one of the audio channels.

Use of third-party applications for recording
When built-in capabilities are lacking, Google Play Market apps come to the rescue, with XRecorder, AZ Screen Recorder and DU Recorder leading the way, offering more flexible bitrate settings, FPS and real-time drawing on-screen.
Installing third-party software requires careful permissions, and when it first starts, the app will request access to the display over other windows and media, and without these permissions, the recording functionality will be inoperable or limited.
However, third-party solutions have downsides: the presence of advertising, watermarks and greater battery consumption. Xiaomi's built-in recorder is optimized for hardware devices, while third-party programs run in a more resource-intensive mode, which can cause FPS to fall in heavy games.
- 📹 XRecorder: Minimalist design, there is video editing.
- 🎮 AZ Screen Recorder: Support for streaming and webcam.
- 🚀 DU Recorder: High stability, but plenty of advertising in the free version.
Optimizing the quality and preserving the battery
Recording high-resolution video (1080p and above) at 60 frames per second puts a heavy strain on the processor and battery. To avoid overheating and trolling (decreased performance), it is recommended to reduce the quality settings for long sessions. The optimal balance is considered to be 720p resolution at 30 FPS for training videos.
Be sure to turn on Do Not Disturb mode before recording. An incoming call or notification can interrupt the recording, leave personal information on the screen or cause a system failure. On Xiaomi, this mode can be configured to turn on automatically when you start the Screen Record application.
For maximum video quality, use the codecs supported by your device. In the recorder settings, you can often choose between H.264 and H.265 (HEVC). The H.265 codec provides better quality with a smaller file size, but may not be supported by older video players or PCs.
💡
Optimal settings for the balance of quality and performance: 1080p resolution, 30 FPS, bitrate 12 Mbit / s, MP4 format.
