Screen recording on Xiaomi Mi 9T: all ways with settings and nuances

Why you need to record the screen on Xiaomi Mi 9T and what to consider before you start

Screen recording on Xiaomi Mi 9T (also known as Redmi K20 in some regions) can come in handy in dozens of situations, from creating guides for friends to fixing bugs in games or saving streams. However, not everyone knows that the smartphone based on MIUI offers several ways to record at once, both built-in and through third-party tools. The main difference between the Mi 9T and other Xiaomi models is support for recording at 1080p at 60 frames per second, but with restrictions on the duration of the video.

Before you start, check two critical things: the MIUI version (old builds may not have built-in functionality) and free space – a minute of Full HD video “weighs” about 100-150 MB. Also note that recording system sounds (such as music from apps) is often blocked due to Digital Rights Management (DRM) policies.

In this article, we will analyze all current methods, from the standard tool Screen recording in the notification curtain to professional applications like AZ Screen Recorder or DU Recorder. Particular attention will be paid to quality settings, recording sound from the microphone and solving typical problems - for example, when a recording breaks down at 30 seconds or video is saved without sound.

Method 1: Integrated screen recording in MIUI (without root)

The easiest and safest method is to use the built-in screen recording feature available in the Xiaomi Mi 9T on MIUI 11 and later, its main advantage is that you do not need to install third-party applications, which reduces the risk of viruses or data leaks, but there are also disadvantages: limited settings (no bitrate choice) and the inability to record internal sound without additional manipulation.

To activate the recording:

1. Turn the notification bar (swipe down from the top edge of the screen).
2. Find the screen recording icon (if there is none, tap on “Edit” and add manually).
3. Click on the icon and confirm the start of the recording (the countdown timer will appear).
4. To stop, roll the curtain again and tap on the recording notification.

Videos will be saved in the DCIM → ScreenRecordings folder in.mp4 format. By default, the resolution is 720p, but it can be changed:

• 📱 Go to Settings. → Special facilities → Screen recording.
• 🎥 Select the quality of the video (available) 480p, 720p or 1080p).
• 🎤 Enable sound recording (only from microphone!).
• ⏱ Set an autostop timer (from 1 to 30 minutes).

💡

If the recording icon disappeared from the curtain after the MIUI update, reset the notification panel settings: Settings → Notifications → Additional → Reset the panel settings.

Method 2: Recording with internal sound (DRM bypass)

One of the most common problems when recording a screen on the Xiaomi Mi 9T is the lack of sound from applications (for example, music in games or videos in the browser), this is due to DRM protection, which is legally impossible to circumvent without root rights.

If you are critical to record internal sound, use an external microphone (e.g., headphones with a microphone) and enable audio playback through the speaker. Alternatively, applications like AZ Screen Recorder with Internal Audio function, but they require a PC connection to activate via ADB.

Enable USB debugging in Settings → About Phone → MIUI version (stamp 7 times)

Install AZ Screen Recorder from Google Play

Connect your phone to your PC and execute adb shell sh /sdcard/Android/data/com.hecorat.screenrecorder.free/files/start.sh

Reboot your smartphone

For advanced users, there is a method using Xposed Framework or Magisk, but it requires unlocking the bootloader and installing a custom Recovery. On the Xiaomi Mi 9T with MIUI 12.5+, this method can lead to some features being blocked (such as Google Pay) due to SafetyNet triggering.

Method 3: Third-party applications – comparison and settings

If the built-in tools don't work, look at third-party apps, which offer more options: bitrate selection, webcam overlay, drawing while recording, and even streaming on YouTube.-3 applications for Xiaomi Mi 9T:

To install any of these applications:

1. Download APK from the official website (avoid third-party sources!).
2. Allow installation from unknown sources in Settings → Applications → Special Access.
3. Launch the app and provide all the permissions you have requested (especially overlaying over other windows).
4. Configure the recording options: resolution, bitrate (8-12 Mbps for Full HD is recommended) and sound source.

Method 4: Recording screens via PC (for long videos)

If you need to record long-term gameplay or streaming (like streaming to Twitch), the Xiaomi Mi 9T's built-in tools may not be suitable due to time constraints, in which case recording via a computer using programs like OBS Studio or ApowerMirror will help.

This will require:

• 🖥 Install it on a PC. OBS Studio (free) or ApowerMirror (paid version with advanced features).
• 📱 Connect Mi. 9T PC-only USB-cable (enable file transfer mode).
• 🔄 V OBS Studio add source Capture Android device (you will need to enable debugging by USB).
• 🎬 Set up resolution and bitrate manually (recommended) 1920×1080 upon 30 FPS stability).

The advantage of this method is that there are no restrictions on duration and the ability to record internal sound (if you stream audio to a PC via Virtual Audio Cable), but there are also disadvantages: image delay (~1-2 seconds) and the need for a powerful PC to process the flow.

Typical problems and their solutions

Even with the right settings, recording the screen on the Xiaomi Mi 9T can malfunction. Here are the most common errors and ways to fix them:

⚠️ Warning: If the recording automatically stops after 30 seconds, check for free space on the device. MIUI Forced interrupts the recording with a balance of less than 500 MB.

If none of these methods worked, try resetting the application settings for the writing tool:

1. Go to Settings → Applications → Application Management.
2. Find a Screen Record (or a third-party app).
3. Slip the vault. → Clear the data.
4. Reset the device.

Optimizing video after recording

Recorded video often requires editing, trimming, quality improvement, or compression, and both mobile and desktop tools are suitable for this:

• 🎬 CapCut (mobile) – free editor with stabilization and color correction functions.
• 🖥 HandBrake (PC) – for video compression without loss of quality (use Fast preset) 1080p30).
• 📱 InShot – convenient for quick trimming and adding subtitles.
• 🌐 Clideo (online) – if you need to cut video without installing programs.

To reduce the file size without significant loss of quality:

1. Open the video in HandBrake.
2. Select MP4 and H.264 (AVC) codecs for video, AAC for sound.
3. Set a constant bitrate (CRF) at 20–23.
4. Activate the 2-Pass Encoding option for better compression.

💡

For gameplay recording on Xiaomi Mi 9T, the optimal settings are: 1280×720 resolution, 6 Mbps bitrate, FPS 60. This is a balance between quality and file size.
