Xiaomi’s “Failed to Encode Video”: What It Means and How to Fix It

Have you tried to record a video on a Xiaomi smartphone, but instead of a saved video, you got a message saying, “Couldn’t encode the video”**? Or an editing app (like Mi Video or CapCut) suddenly interrupted processing with the same error? This problem occurs on Redmi, POCO and Mi devices regardless of the MIUI version — from the old Redmi Note 4X to the flagship Xiaomi 14 Ultra.

Video encoding error is not a critical system failure, but it makes it impossible to save important points or edit videos. 80% of the time, the cause lies in software conflicts, overloaded memory or codec incompatibility. Less commonly, the fault is “iron” (for example, overheating of the processor or a damaged camera module). In this article, we will analyze all possible causes of the error “failed to encode video” on Xiaomi and give clear instructions for elimination – from simple reboots to deep system settings.

What does the error mean “Can’t encode the video”?

The message “Failed to encode video”** appears when Xiaomi’s system cannot complete the process of converting raw data from the camera (or from the buffer) to a ready-made file in the format of.mp4,.mov or.mkv. Encoding is the “compression” of video using special algorithms (codecs), and if at some stage there is a failure, the file is either not saved or it is corrupted.

Here’s what happens under the hood at the time of the error:

It is important to understand that this error is not related to a physical failure of the camera (unless the module itself is damaged).

• 🔄 PO conflicts: failures in MIUI Camera, Google Camera or mounting apps.

Reasons for the error on different Xiaomi models

The nature of the error may vary depending on the smartphone model and the MIUI version. Below is a table with typical causes for different lines:

For example, owners of Redmi Note 10 Pro often encounter an error when writing in 4K@60fps due to the limitations of the Snapdragon 732G chip. And on POCO F3, the problem can be due to the malfunction of GCam after manual patching of configs.

💡

If the error occurred after the MIUI update, try rolling back to the previous version via Settings → About Phone → System Update → Three Points → Select the Service Pack.

How to fix video encoding error: step-by-step instructions

Start with the simplest solutions and gradually move on to the more complex ones. Most users solve the problem in the first 3-4 steps.

1.Reboot the smartphone

It's trivial, but it works 30 percent of the time, and if you run in the background, you can accumulate errors in the camera module or codecs, and reboots your RAM and resets your temporary files.

Hold the power button for 10 seconds | Select "Reset" | After turning on, check the camera | If the error persists, proceed to the next step-->

2. Clear the cache and data of the Camera app

Accumulated temporary files or corrupted data can interfere with proper encoding.

1. Go to Settings → Applications → Application Management.
2. Find the camera (or Mi Camera).
3. Click Warehouse → Clear the cache and Clear the data.
4. Reboot the phone.

Attention! Clearing the data will reset the camera settings (e.g., default resolution).

3. check the free space on the phone

For video coding, free space is required in 2-3 It's twice the size of the final file, for example, to record. 1 minute 4K-Video needs to be about 1.5-2 GB of free space: delete unnecessary files or transfer them to a memory card.

- 720p: 500MB

- 1080p: 1.5 GB

- 4K: 3GB

- 8K: 5+GB-->

4. Turn off the energy saving mode

Battery or Ultra modes in MIUI limit processor performance, which can interrupt video encoding.

• Go to Settings. → Battery.
• Select the Performance mode.
• Turn off Adaptive Charging and Battery Optimization for the Camera.

5. Reset the camera settings to factory

If the error only appears when certain settings (e.g. HDR or 60fps) are set, reset the settings:

1. Open the Camera app.
2. Touch the gears (⚙️) or swipe up for settings.
3. Find the Reset (or Restore by default) option.

6. Update or reinstall the firmware

If the error occurred after the MIUI update, possibly in the firmware bug.

• Go to Settings → About the phone → System update.
• If there are no updates, try manually flashing through the Mi Flash Tool (instruction below).

Advanced solutions for experienced users

If the basic methods didn't work, try the following: They take more time and technical knowledge, but often solve the problem.

1. Change the video codec manually

Some Xiaomi models default to HEVC (H.265) codec, which can conflict with iron.Switch to AVC (H.264):

1. Install the Camera2 API Probe app from Google Play.
2. Check if your device supports H.264 at the right resolution.
3. If yes, use a third-party camera (such as Open Camera) with manual codec selection.

2. Disable hardware acceleration of coding

On some devices (e.g. Redmi Note 11 with Snapdragon 680), hardware encoding via MediaCodec is unstable.

adb shell setprop media.stagefright.enable-player false

This command disables hardware acceleration for media files. Once done, restart the phone.

3. check the integrity of the camera module

If the error occurs even when writing in 480p, there may be a hardware malfunction.

• Install the AIDA64 or CPU-Z app.
• Check the Camera section – all modules are defined.
• If one of the sensors is missing (such as Wide or Macro), contact the service.

💡

On devices with high humidity (water intake, condensation), the coding error may appear due to the oxidation of the contacts of the camera module, in which case only repair will help.

4. Install custom software (for advanced ones)

If the problem is firmware, but official updates do not help, consider custom builds:

• 📌 LineageOS is a stable alternative MIUI.
• 📌 Pixel Experience – Google’s camera firmware (without Mi Camera bugs).
• 📌 Xiaomi.EU – modified MIUI limitless.

⚠️ Attention! Custom software installation requires unlocking the bootloader and may be insecure. 4PDA for your model.

Frequent Questions (FAQ)

When should I contact the service?

If you tried all the methods in the article, but the error "Can not encode the video"** remained, perhaps the problem in the hardware.

• 🔴 The bug appears in all apps (including Open Camera and Snapchat).
• 🔴 The phone warms up even with a short recording.
• 🔴 V AIDA64 One or more camera modules are not displayed.
• 🔴 Before the error there were physical injuries (fall, moisture infestation).

The cost of repairing a camera module in Xiaomi varies from 1,500 to 5,000 rubles depending on the model. In authorized centers, the warranty for repair is 6 months.

💡

Before visiting the service, make a backup copy of the data - during the diagnosis, you can reset the phone to factory settings!

Conclusion: Short checklist to eliminate the error

For convenience, we've put all the steps in one list.

Reboot the phone.|Clear the cache and data of the Camera app»|Check the vacant space (minimum 3GB)|Turn off the energy-saving mode.|Reset the camera settings|Update. MIUI or run another version|Try a third-party camera (Open Camera, GCam)|Check the camera module for hardware damage-->

If none of these things work, it's probably hardware, and you can't do it without repair, but 90 percent of the time, it's software-based, without going to the service.
