Screen recording on Xiaomi smartphones is a useful feature for creating guides, streams or saving important moments from games and applications. However, many users face problems: recording is obtained in jerks, low resolution or artifacts, the reason often lies in the wrong settings or limitations of the standard Screen Recorder tool.
In this article, we’ll break down 7 ways to improve recording quality, including hidden MIUI settings, alternative apps and tech tricks for models from Redmi Note 10 to Xiaomi 14 Ultra. You’ll learn how to record a screen in 4K, boost FPS to 120Hz, and avoid lags during long sessions.
Why is the standard screen recording on Xiaomi poor quality?
The built-in recorder in MIUI is optimized for the balance between quality and performance, but does not always meet the requirements of users.
- 🔍 Restriction of permission: by default, the record goes to 720p or 1080p, Even if the screen supports 1440p.
- 🎞️ Video compression: codec is used H.264 high compression level, which leads to artifacts.
- ⚡ Limits FPS: On most devices, the maximum frame rate is 30. FPS, What's not enough for dynamic scenes.
- 📱 Overheating of the processor: with prolonged recording of Snapdragon or MediaTek, trottlit, reducing smoothness.
For example, on the POCO F5 with a 120 Hz screen, the standard recorder only captures 30 FPS, and on the Xiaomi 13T Pro, even in 4K video, it gets with noticeable noises due to aggressive compression. There are solutions - and they do not require root rights.
Method 1: Set up the built-in Screen Recorder in MIUI
The first thing to try is to optimize the standard application, with the latest versions of MIUI 14/15 offering hidden quality improvements:
- Open Settings → Special Options → Screen recording.
- Enable the option "High quality" (if available).
- Go to the additional settings and install: 📏 Permission: 1080p (maximum for most models). 🎯 Bitrate: 12–15 Mbps (the higher, the fewer artifacts). 🔄 Frequency of frames: 60 FPS (if maintained).
"Mic recording"
Xiaomi. 12S Ultra and newer in the developer menu (Settings) → The phone. → Version. MIUI → 7 Once you tap, there is an option force_screen_record_4k, recordable 2160p. But remember, the files will weigh. ~1 GB/min.
💡
Before recording, close all background apps through Settings → Apps → Clean. This will free up RAM and reduce the risk of lag.
Method 2: Use of alternative applications
If the built-in recorder is not satisfied, install one of these applications (checked on MIUI 14-15):
| Annex | Max, permission. | Max. FPS. | Bitreit | Features |
|---|---|---|---|---|
| AZ Screen Recorder | 4K | 120 FPS | Up to 50 Mbps | HEVC (H.265) support, no watermarks |
| DU Recorder | 2K | 60 FPS | Up to 20 Mbps | Built-in editor, streaming on YouTube |
| Mobizen | 1080p | 60 FPS | Up to 16 Mbps | Support for recording from the front camera |
| Vysor | 1080p | 30 FPS | Up to 10 Mbps | Recording via PC (needed) USB-cable) |
To install AZ Screen Recorder (recommended for games):
- Download APK from the official site (avoid Google Play - there is a stripped-down version).
- In the application settings, select: 📹 Permission: 3840×2160 (4K). ⚡ FPS: 120 (if the screen supports). 🎚️ Bitreit: 30–50 Mbit/s. 🔧 Codec: H.265 (HEVC) for lesser file weight.
"Use hardware acceleration."
Set 1080p or 4K resolution (if supported) |
Select the H.265 (HEVC) codec |
Set the bitrate 25-50 Mbit/s|
Turn off microphone recording (if no sound is needed)|
Enable hardware acceleration-->
Method 3: Optimizing the performance of the phone
Even with the best settings, recording can be slowed down due to processor trottling or lack of RAM.
- ❄️ Cooling: Use a cooling case or fan (such as Black Shark FunCooler) for models with Snapdragon 8 Gen 2.
- 🔋 Performance mode: Enable in Settings → Battery → Modes of the option "Maximum productivity".
- 🗑️ Cache Clearing: Before writing, perform Settings → Memory. → Clear the cache.
- 🔌 Charging: Connect your phone to charging (better with Quick Charge 4 support)+), Avoiding Energy Conservation Restrictions.
Nana POCO X5 Pro and Redmi. K60 there's a hidden option force_high_performance_mode, activatable ADB:
adb shell settings put global force_high_performance_mode 1This will disable heating restrictions but reduce battery life.

Method 4: Recording via PC (for maximum quality)
If you want to burn the screen in 4K@120FPS without loss of quality, use the projection on the PC and then write it through OBS Studio or NVIDIA ShadowPlay.
- Connect Xiaomi to your PC via USB-cable (preferably original).
- Enable USB debugging (Settings → About Phone → MIUI Version → 7 taps → For developers → USB debugging).
- Install the Android SDK Platform-Tools on your PC.
- Run the command to project the screen: adb exec-out screenrecord --bit-rate 50M --size 3840x2160 /sdcard/record.mp4 Settings: --bit-rate 50M -- bitrate 50Mbit/s. --size 3840x2160 -- 4K resolution. --time-limit 600 -- time limit (600 seconds = 10 minutes).
Ctrl+C
Alternatively, use scrcpy (a free screen mirroring utility):
scrcpy --bit-rate 50M --max-fps 120 --record file.mp4💡
Recording via ADB or scrcpy is minimally lossy, but requires a PC connection, optimal for streamers or professional guides.
Method 5: Configure codecs and containers
Video quality is not only resolution-dependent, but also codec and container-based. MIUI uses H.264 in MP4 by default, but there are more efficient options:
- 🎥 H.265 (HEVC): It compresses video 2 times stronger at the same quality. AZ Recorder and DU Recorder.
- 📦 MKV: A container that allows you to store multiple audio tracks without loss, useful for multichannel audio.
- 🔊 Opus: codec for sound, better AAC low-bitrate.
To include HEVC in AZ Recorder:
- Go to Settings. → Video quality.
- Select "Code: HEVC (H.265)".
- Set Profile: Main10 for 10-bit color (if supported).
On Xiaomi 13 Pro and later, you can activate the HEVC hardware encoding via ADB:
adb shell setprop media.stagefright.enable-hw-hevc 1💡
To edit video in HEVC, use Adobe Premiere Pro (version 2022+) or DaVinci Resolve – they support hardware decoding.
Method 6: Solving problems with lags and artifacts
If the video is in jerks or the video is "breaking", check out these moments:
| Problem. | Reason. | Decision |
|---|---|---|
| Punch every 5-10 seconds | Processor overheating | Use cooling or lower the resolution to 1080p |
| Green/purple artifacts | H.264 codec failure | Switch to H.265 or lower the bitrate to 10 Mbps |
| Video and sound are not synchronized | Delay in recording microphone | Turn off the sound or use an external microphone |
| The recording ends in 3-5 minutes. | Limitation of MIUI on background activity | Add a recorder app to battery exclusions |
On the Redmi Note 12 Pro+ and other devices with MediaTek Dimensity can help disable the “Intelligent Resource Allocation” in the battery settings.

Method 7: Post-processing video to improve quality
Even if the recording is not perfect, it can be improved with the help of software:
- 🎬 Topaz Video AI: increase the resolution 4K and recovers lost details.
- 🔍 Adobe Premiere Pro: Warps Stabilizer Tool Eliminates Trembling.
- 🎚️ HandBrake: Recodes video with bitrate and codec settings.
- 🔊 Audacity: cleanses sound from noise (useful when recording from a microphone).
Example of commands to improve via FFmpeg:
ffmpeg -i input.mp4 -vf "unsharp=5:5:0.8:3:3:0.4" -c:v libx265 -crf 20 -preset slow -c:a copy output.mkvThis team:
- It is used to increase the sharpness (unsharp).
- Recoded to H.265 with high quality (CRF 20).
- It retains the original sound (-c:a copy).
💡
Post-processing won't bring back lost details, but it can greatly improve video perception, for example, increasing the bitrate from 5 to 15 Mbps reduces artifacts by 60 percent.
