The owners of Redmi smartphones and POCO A common feature in the standard utility suite is an icon called Screen Recorder, or Screen Recorder, which is not just a third-party program, but is deeply integrated into the shell. MIUI or HyperOS, a system module that allows you to capture what's happening on the display without having to download dubious software from the Internet, which many users ignore, relying on third-party solutions that are often overloaded with advertising or require unnecessary permissions.
But the built-in app has a number of advantages that competitors can't: it can record the internal sound of the system, which is critical to creating training videos or playing moments without extraneous noise. System optimization allows you to record in high resolution, with little to no impact on the performance of the device in the background.
In this article, we’ll look at how to set up codec options, where to look for ready-made files, and why this tool is one of the most underrated in the Chinese manufacturer’s ecosystem. Understanding its functionality will help you create professional-level content right from your phone.
What is the MIUI system recorder?
At its core, Screen Recording is a multimedia combines screenshot, voice recorder and video editor functions. Unlike standard Android, where functionality is often limited to basic capture, Xiaomi’s solution offers flexible bitrate and frame rate settings. Hardware acceleration of the Snapdragon or MediaTek processor is used to encode real-time video, which minimizes battery load.
The key feature is that you can choose the source of the audio stream, so you can record only the microphone, only the system sounds, or mix them, and that makes it universal: gamers write walkthroughs with the clear sound of the game, and teachers write lectures with voice commentary on top of the image.
⚠️ Note: When activating a system sound recording during an incoming call, the recording may automatically be interrupted or the caller's sound may not be recorded due to Android's privacy policy.
The program interface is as simplified and adapted to one-handed control. After the session is over, the file is automatically saved in the gallery, where it can be edited immediately: cropped, added stickers or text. MP4 format ensures compatibility with any media players and social networks.
💡
The built-in recorder uses system resources more efficiently than third-party counterparts, providing stable FPS even in heavy games.
Configuring quality parameters and resolution
To access the advanced settings, you need to launch the app and click on the gear icon in the top corner, and this opens a menu where the user can fine-tune the parameters of the future video file, and resolution is the first important parameter that directly affects the clarity of the image and the weight of the file.
The options available depend on your smartphone’s matrix capabilities. Xiaomi 13 or Xiaomi 14 flagship models let you choose 1080p and even 4K, whereas the budget Redmi Note series can be limited to 720p or 1080p. The higher resolution option is only advisable if you plan to display video on the big screen or mount it.
- 🎥 Resolution: Determines the number of pixels (e.g, 1920×1080).
- 📉 Bitrate: Affects the detailing and file size (the higher the quality, but the more weight).
- 🎞️ Frequency: Standard 30 FPS or smooth 60 FPS dynamically.
- 🔊 Sound source: microphone, system sound or a combination of both.
Bitrate is often underrated. Automotive tries to balance quality and size, but for text writing or static interfaces, you can manually lower the value to save space. For games, on the contrary, you should set maximum values to avoid the appearance of "squares" (artifacts) in a rapidly changing picture.
Sound control: microphone and system noise
One of the most popular features is internal audio recording, which used to require complex root rights manipulation, but modern versions of Android 10+ and MIUI shells allow you to do this natively. In the audio settings, you can choose System Sounds mode, which allows the viewer to hear notifications, music from the player and interface sounds.
If you're creating educational content that you want to comment on, switch to Microphone or System Sounds and Microphone, which is the latter of which the voice will be superimposed over the interface sounds, and it's important to remember noise cancellation: if you're in a noisy place, the voice may not be audible, so you'd better use a headset.
Path to settings: Screen recording → Settings (cogs) → Sound effects → Source selectionIt’s worth noting the nuance of messengers: Some apps, such as WhatsApp or Telegram, can block audio capture during calls within the app for security reasons, in which case the recording will go either without sound or only from the microphone, if the appropriate mode is selected.
💡
To record a clean voice on top of the game, connect wired headphones with a microphone - this will reduce the noise of fans and keyboards in the recording.
Screenshots, timer and floating window
The recording control interface is placed in a floating window that can be dragged around the screen so that it doesn't interfere with viewing. This is especially convenient in horizontal gaming mode. The start button is usually hidden so as not to take up space, and appears when you swipe from the edge of the screen or click on a hidden panel.
There are additional tools available inside the control menu, and the timer allows you to delay recording by 3 or 5 seconds, which gives you time to roll the menu and take the right position. The "Show Touch" feature visually displays the touch points on the screen, which is extremely useful for video instructions.
| Function | Description | Where applicable |
|---|---|---|
| Timer. | Delayed start (3/5/10 sec) | Preparation of the stage |
| Showing touches | Visualization of clicks | Tutorials |
| Camera (front) | Face recording in the corner | Reactions, streams |
| Drawing | Marker over the screen | Focusing on the situation |
There's also a feature called over-screen drawing, so you can use a color marker to highlight important buttons or text while you're recording, and all the lines you draw are saved in the final video, making the instruction more understandable to the viewer.
Where to look for ready-made records and how to edit them
When you stop recording, the file is automatically saved to the gallery. The path to the folder usually looks like internal memory. → DCIM → screen_recorder. If you connect your phone to your computer, you can find the video at this address.mp4, This ensures that they are opened on any device.
The built-in editor in the MIUI gallery allows you to perform basic processing. You can crop the video by removing the redundant at the beginning or end, change the aspect ratio for Stories Instagram or TikTok, and apply filters. The editing tools are simple enough, but they are enough to quickly prepare the video.
⚠️ Warning: When editing the original file, always make a copy of it or save it as a new file so you don’t lose the original high-quality record.
For more complex editing, adding transitions or music, files are easily exported to third-party applications like CapCut or VN. The high bitrate of the source provides a margin of quality even after being recompressed by social networks.

The Solution: Why There's No Sound or Black Screen
Users sometimes experience a situation where video is recorded but without sound, or instead of an image, a black screen, and most often the problem lies in the permissions. When you first run the application requests access to the microphone and files — if you accidentally refuse, the functionality will be limited.
The black screen when recording videos from Netflix, Disney+ or banking apps is not a bug, but a copy-of-content (DRM) protection technology that prevents the protected video stream from being captured, and the system replaces it with a black rectangle, which is impossible to get around with standard means.
- 🔇 No Sound: Check if the phone is in silent mode and if the correct source is selected in the recorder settings.
- ⬛ Black Screen: Attempting to Record Protected Content (DRM) or use of a theme with modified system fonts.
- 📉 Low. FPS: too many background applications running, there is not enough RAM.
If the video slows down, try lowering the resolution or frame rate in the settings, cleaning the RAM before you start recording for a long time also helps, and in rare cases, resetting the settings of the application itself through the Applications menu helps.
