Mobile devices of the modern line Xiaomi and Redmi have powerful functionality that is often hidden in the depths of the interface MIUI or HyperOS. One of the most popular, but not always obvious features is the built-in screencaster. Users no longer need to look for third-party applications full of ads, since the system tool allows you to capture what is happening on the display in high quality.
This option may need to be activated to create training videos, fix bugs in games or save correspondence. Xiaomi's built-in recorder saves the video directly to the gallery without watermarks and time limits. However, to get started, you need to properly configure microphone settings and resolutions, which we will discuss in detail below.
Next, we will discuss all the nuances of the system tool, including hidden audio settings and ways to solve typical problems, you will learn how to make the process of capturing the image as convenient and high-quality for your purposes.
Where to find and how to activate the recording function
By default, the voice recorder icon is not displayed on the home screen or in the Quick Settings Panel. To access it, you need to open the notification curtain. Swipe down from the top edge of the display to open the control menu. If you don't see the icon right away, click on the edit button (usually a pencil or three dots in the corner).
In the list of available widgets, find an item called Screen Recorder or Screen Recorder. Drag it into the fast switch active zone. After that, you can start the process with a single touch. Alternatively, use the voice assistant Google Assistant or Xiao AI, saying the corresponding command.
You can also run through the multitasking menu or customization, and in some versions of the firmware, the path looks like this: Settings → Advanced Settings → Screen recording, and you can immediately go to fine-tuning the settings before you start using them.
Configuring the sound and microphone parameters
The critical thing is to choose the source of the audio signal, and when you first run it or through the application settings, you'll be offered several options, depending on whether you're heard, whether you're heard, whether you're heard, whether you're heard, whether you're heard, whether you're heard, whether you're heard from the system or if you're not.
Let’s look at the main modes of operation of the microphone:
- 🔇 No sound: video is recorded completely without audio track, useful for sensitive data or if audio is added during editing.
- 🎤 Microphone: only external sounds that are picked up by the smartphone microphone are recorded. Voice messages in instant messengers and system sounds of the game will not be recorded.
- 🔊 System sounds: the internal audio stream of the device is recorded, ideal for gameplay or demonstration of application work, voice through the microphone will not be written.
You can use a floating window to switch modes during recording, and click on the microphone icon in the recorder interface to change the sound source on the fly, and note that when you call in, the recording of the sound may be interrupted.
⚠️ Warning: When you try to record a video in secure apps (such as Netflix or banking services), the screen may turn black and the sound may go awry due to politics. DRM safety.
Choice of permission and staffing frequency
The quality of the final video depends on the selected parameters in the settings menu. The standard MIUI interface offers flexible bitrate and resolution management. By default, a value is often set that corresponds to the resolution of your screen, but it can be changed to save space.
To create smooth videos, especially in dynamic games, it is important to set the correct frame rate. The standard value is 30 FPS, however, for maximum smoothness, choose 60 FPS if the device's processor copes with such a load without overheating.
A comparison of popular quality settings is presented in the table below:
| Parameter | Permission | Recommended use |
|---|---|---|
| SD (Low) | 480p / 720p | Demonstration of bugs, quick reports |
| HD (Mediocre) | 1080p | Social networks, messengers |
| FHD (High) | 1080p / 1440p | Gameplay, YouTube, reviews |
| 4K (Maximum) | 2160p | Professional content, installation |
Remember that increasing resolution and bitraid results in a quick filling of internal memory. Before starting a long session, make sure you have free space.
💡
Use MP4 format for maximum compatibility with social media and editors.MKV format may require conversion.
Working with the interface and timer
The recording interface is designed to keep the screen from overlapping the usable area, and when you start, you have a floating control panel in the corner, and you can move it around the display so that it doesn't interfere with the viewing of games or applications.
The panel's functionality includes:
- ⏱ Timer: This shows the duration of the current session, and you can set a time limit after which the recording will stop automatically.
- 🖊 Drawing: allows you to take notes directly on the screen in real time, and it's convenient for creating educational materials.
- 📸 Screenshot: the ability to take a screenshot without interrupting the video.
- ⏸ Pause: Temporary recording stop without creating a new file.
To complete the process, click the stop button. The file will automatically be saved to the ScreenRecorder folder in the gallery. If you used the drawing, it will be "sewn" in the video and will not require additional editing.
☑️ Pre-recording checks
Hidden functions and drawing on the screen
Few people know that the built-in tool allows you not only to capture an image, but also to interact with it. The drawing function is activated via a floating menu. You can choose the color and thickness of the line to highlight important interface elements for the viewer.
This is particularly useful when you're creating instructions for colleagues or friends, and instead of using your voice to explain where the button is, you can just circle it in red while you're recording, and all the cursor or finger actions are stored in the final video file.
You can also turn on touch display in the settings, and it adds a visual effect (a circle or a dot) to the place where you touch your finger, which is a standard feature for developers, but it helps a lot with training videos.
⚠️ Warning: Turning on the touch display can distract the viewer in a regular video, so use this option only for technical demos.
The Solution: Why There's No Sound or Video
Sometimes users are faced with a situation where video is recorded but without sound, or the file is not created at all, most often the problem lies in the permissions of the application. Android system strictly controls access to the microphone and storage.
Check the permission settings:
- Go to Settings → Applications → All applications.
- Find Screen Recorder or Screen Recorder in the list.
- Select the Permission.
- Make sure that Microphone and Memory access is activated.
If the problem persists, try clearing the app's cache through the same menu, in rare cases, rebooting the device helps, and also make sure that no silent mode is turned on, which can block the recording of system sounds.
What to do if the recording is interrupted?
💡
In most cases, the absence of sound is resolved by the correct choice of source (Microphone vs System Sound) at the time of recording launch.
