How to transfer video to a memory card in Xiaomi: 5 proven ways

Why transfer the video to the SD-map?

Xiaomi smartphones based on MIUI Often face a lack of internal memory, especially if you are actively shooting high-resolution video. 4K-And when you put in videos, you get tens of gigabytes of video, and you start to slow down when you fill up the storage by 80 percent, and you can transfer the video to the microSD card, you can solve three problems:

1) Frees up space for new files and speeds up the phone. 2) Extends the life of the internal drive (flash has a limited record life). 3 Simplifies backup - just extract SD-But in the MIUI There is no universal method of transfer: the method depends on the firmware version, the phone model (Redmi Note 10 Pro, POCO X3, Mi 11) and even from the video format (.mp4,.mov,.mkv).

In this article, we will discuss the current ways for MIUI 12-14, including bypassing the restrictions of Android 11+ on writing files to external media, we will also analyze common errors (for example, “Insufficient rights” or “File not moved”) and give recommendations for choosing a memory card for Xiaomi.

Preparation: Which memory card to choose for Xiaomi?

Not all microSDs are suitable for video recording, especially in 4K resolution or high bitrate. Xiaomi smartphones are optimal cards UHS-I U3 or V30/V60/V90 – they guarantee a recording speed of 30 MB / s. Here are the key parameters:

⚠️ Attention: Format maps FAT32 They do not support file sizes >4GB If you are shooting long videos in 4K, Choose exFAT (but note that some older Xiaomi models may not read this format).

Before buying, check compatibility with your phone model. For example, Redmi 9A supports microSD up to 512 GB, and POCO F3 up to 1 TB. You can specify the maximum volume on the official Xiaomi website or through the AIDA64 application (Store section).

Method 1: Move through the built-in MIUI file manager

The easiest method is to use the standard Files app (yellow folder icon) which works on all Xiaomi smartphones with MIUI 12 and later, but has a limitation: you can not move files protected by DRM (for example, downloaded from Netflix or Disney+).

Instructions:

1. Open the Files app → go to the Video section.
2. Press and hold the video you want to transfer (to select several files, tap the circles on the right).
3. In the lower menu, select Move (the arrow folder icon).
4. In the tapneta storage list SD-map → Select a folder (for example, DCIM or Videos) → Move it.

If the button is inactive:

• 🔹 Check that the memory card is formatted as portable storage (not as internal memory).
• 🔹 Make sure you're on SD-enough space (minimum reserve - 10% of the file size).
• 🔹 Try to reboot your phone – sometimes MIUI Blocks operations with files after a long period of work.

Method 2: Use Portable storage vs Internal memory

Android offers two formatting options SD-Cards: as portable storage (files can be transferred manually) or as internal memory (card becomes part of the system), the second option is convenient for installing applications, but has risks:

⚠️ Note: If you format the card as internal memory, it can't be retrieved without losing data. SD-map will be erased.

To transfer the video without restrictions:

1. Go to Settings. → Warehouse.
2. Tap your name on it. SD-map → Settings (three dots in the upper right corner).
3. Select Format as a portable storage (if the card is already formatted as an internal one, pre-return the data!).
4. After formatting, repeat the steps from Method 1.

If you still want to use the card as internal memory (for example, to record video directly to SD), consider:

• 🔹 Video will be saved to the map automatically only if the camera settings selected Storage. → SD-map.
• 🔹 The recording speed may drop if the class card is lower U3.
• 🔹 Some apps (such as TikTok or Instagram) won’t be able to save videos to internal content. SD-map.

Method 3: Transfer video over PC (for large files)

If the video weighs several gigabytes (for example, hourly) 4K-It can take 20 to 40 GB to move through a phone, it can take hours or it can be a mistake:

• 🔹 Cable USB Type-C (preferably original from Xiaomi).
• 🔹 Card reader (if the laptop does not have a microSD slot).
• 🔹 Copying software (e.g. TeraCopy for Windows or rsync for Windows) macOS/Linux).

Step-by-step:

1. Connect your phone to your PC in File Transfer mode (in the Xiaomi notification curtain, select this option).
2. Open the Internal Storage → DCIM → Camera (or Movies if the video is saved there).
3. Copy the video to your desktop or to a separate folder.
4. Extract. SD-card from the phone and insert into the card reader.
5. Transfer files to the card (it is recommended to use TeraCopy to check check checksums).
6. Securely remove the card and paste it back into the phone.

Critical detail: When copying via PC, never remove a memory card or USB cable during the process – this can cause damage to the file system (especially on exFAT cards).

💡

If the video is not played after transfer, check its integrity through MediaInfo. Sometimes files are copied with errors, especially when using cheap card readers.

Method 4: Automatically save video on SD-map in Xiaomi's camera

To avoid manually transferring video, set the camera to record directly to an external drive.This method works on most Xiaomi models, except flagships with 8K write restrictions (Mi 11 Ultra, 12S Ultra).

How to set up:

1. Open the Camera app.
2. Slap the icon. ⚙️ (Settings) → Warehouse.
3. Choose. SD-card (if the option is inactive, check that the card is formatted as portable storage).
4. Restart the camera and the new videos will be saved to the SD.

Limitations of the method:

• 🔹 Does not work for slow motion – such videos are always stored in internal memory.
• 🔹 In Pro mode (manual settings) can ignore storage selection.
• 🔹 In some models (POCO F4 GT) recording 4K/120fps automatically switched to internal memory.

💡

For a stable record. 4K-video SD-card speed should not be lower than 60 MB / s (class) V60). Otherwise, "teared" frames or breaks of the recording are possible.

Method 5: Transfer Videos over ADB (for Power Users)

If standard methods don’t work (for example, due to MIUI limitations on external media writing), you can use Android Debug Bridge (ADB), which requires a PC and basic command line knowledge, but allows you to bypass most locks.

Instructions:

1. Turn on Developer Mode on your phone: Settings → About Phone → MIUI version (shap 7 times).
2. Return to Settings → Additional → For developers and activate Debugging over USB.
3. Connect the phone to the PC and confirm the debugging permission.
4. Open the command line (Windows) or terminal (macOS/Linux) and type:

adb shell


mv /sdcard/DCIM/Camera/your_video.mp4 /storage/XXXX-XXXX/Videos/

Where:

• your_video.mp4 — filename.
• XXXX-XXXX — unique identifier SD-maps (you can find it by the LS command) /storage).

⚠️ Attention: Misuse of the right ADB Before executing commands, back up the video to your PC. Also avoid transferring system files (for example, from a folder). /data).

Typical errors and their solutions

When you transfer the video to SD-Xiaomi users are facing a few common problems. Here's how to solve them:

If the video is not reproduced after the transfer:

• 🔹 Check the codec: some Xiaomi players don't support.mkv or.avi. VLC or MX Player.
• 🔹 Make sure the file is not corrupted: compare the file size to the original file size.
• 🔹 For 4K-Video may require hardware decoding – enable it in player settings.
