How to change the format of video on Xiaomi phone

Modern Xiaomi smartphones running MIUI or HyperOS shells are great at playing most media files. However, users often face a situation where a particular video is not played by the built-in player or sent through messengers due to unsupported codec or extension, this is especially true when working with high-resolution files or specific containers that are not standard for mobile platforms.

The problem is solved by converting, that is, transcoding the video stream into a more compatible format. There are several effective methods on Xiaomi devices that do not require a connection to a computer. You can use both third-party applications from Google Play, built-in system functions or even cloud services, the choice of method depends on the file size and the frequency of such operations.

In this guide, we will take a look at all the options available for changing the format of video files. We will look at installing specialized converters, working with online platforms, and even touching on the capabilities of the built-in video editor. Understanding the principles of how codecs work will help you avoid loss of quality during transcoding.

Why your phone doesn’t open a video file

The main reason for the system’s failure to play back a file is that it lacks the necessary decoder. Android, as the base for MIUI, has a limited set of built-in codecs to save resources and royalties. If the video is recorded in a rare format or compressed by an algorithm that is not supported by the hardware of your Xiaomi Redmi or Xiaomi Poco, you will see a playback error.

Often the problem is not the file extension itself, but bitrate or resolution that exceeds the CPU’s capabilities. For example, trying to run 4K high-bitrate video on a budget device can lead to sound and image desynchronization or a complete failure to launch, in which case changing the format to a lighter one is the only solution.

⚠️ Warning: Attempting to reproduce a file with an excessively high bitrate can cause the processor to heat up and the battery to discharge quickly, as the system will attempt to decode the stream by software methods.

It is also important to note that some formats are protected. DRM-If you download a movie from a streaming service, you can't change the format with standard means because of the encryption of digital rights.

Use of specialized converter applications

The most reliable and functional way to change the format of video is to install a specialized application. The Google Play Store offers many solutions that work directly on the processor of the smartphone. For owners of Xiaomi, software with support for hardware acceleration is great, which significantly reduces processing time.

One popular option is Video Converter, which allows you to select output formats, change resolution, and even crop video before saving, and the customization process is usually easy even for inexperienced users.

When choosing an app, pay attention to the presence of ads and watermarks. Free versions often add the program logo to the video corner, which may not be acceptable for a personal archive.

• 📱 Video Converter is a universal tool with support for many formats and a simple interface.
• 🎬 Media Converter – allows you to flexibly configure the parameters of video and audio streams.
• 🔄 Format Factory – mobile version of the famous desktop converter with basic functionality.

Once the application is installed, it must be given access to the file system. Without permission to read and write files, the program will not be able to find the original video or save the conversion result in the device's memory.

Step-by-step instructions for conversion through the application

Consider the transcoding process using a typical converter, and most applications have similar algorithms, so this is a good guide for most Play Market applications, so you need to start the installed application and press the file add button.

The next step is to ask the system to choose the target format, and the most versatile for Android devices is MP4 with H.264 codec, which provides good quality with a reasonable file size and is guaranteed to play on any device.

You can change the resolution, for example, to reduce it from 4K to 1080p to save space, you can also adjust bitrate and frame rates, if you are not sure about the settings, leave the default values or select preset "High Quality".

The final step is to start the process. Depending on the power of your Xiaomi and the length of the video, it can take from a few seconds to tens of minutes. During the conversion, the screen can remain on, as the process requires active computing.

⚠️ Note: Do not close the application-converter during the recoding process, otherwise the file may be corrupted and become unreadable.

Once the operation is complete, the program will notify you of the success, and the finished file is usually saved in a folder with the name of the application or in a standard gallery in a separate album.

Online services for changing the format without installing programs

If you only need to convert one file and you don't want to clog your phone's memory with any extra apps, use online services that run directly on Google Chrome or MI Browser installed on your Xiaomi, which is ideal for small files.

The way it works is simple: you upload the video to the server, the server processes it and returns the finished file. Popular services like Convertio or Online-Convert support a huge number of formats. You don't have to install anything, you have a stable Wi-Fi connection enough, because mobile traffic can run out quickly.

The main limitation of the online method is the file size. Free rates usually limit file downloads to 100 MB. Also, the conversion rate depends on the speed of your Internet connection, not the power of the smartphone.

• 🌐 Convertio – supports booting from Google Drive and Dropbox, a user-friendly interface.
• 🚀 Online-Convert – allows you to fine-tune video settings before converting.
• ☁️ CloudConvert – a reliable service with support for cloud storage.

Using online tools also raises privacy issues: It is not recommended to upload personal or confidential video recordings to third-party servers, as you transfer data to third parties.

Built-in MIUI and Google Photos

Many users don’t know that the basic tools of the system can also work with video files, albeit with limited functionality. The Xiaomi Gallery app has a built-in video editor. It doesn’t change the file extension drastically (for example, from MKV to AVI), but can recode videos for social networks.

When you try to send a video through the system (share) to the messenger, the system sometimes automatically prompts you to compress or convert a file if the source format is not supported by the recipient. MP4.

To access basic editing, open the video in the Gallery, click "Change." Here you can crop the video, apply filters, and save a copy. The saved copy will be standard for Android, which will solve the compatibility problem.

This method is suitable for quick editing, but for a full change of codec or container, it is still better to use specialized software described above.

Comparison of video formats for Android

Choosing the right format is key to successful playback. Not all containers are equally useful for mobile devices. Below is a table that will help you determine your target format for conversion.

As you can see from the table, MP4 remains the gold standard, balancing quality and size, and is supported by almost any device, from an old button phone to a modern 8K TV.

MKV format is often used to store movies with multiple audio tracks and subtitles. If your Xiaomi player doesn't open MKV, the easiest way to convert it to MP4 while still maintaining image quality.

💡

When converting, always keep a bitrate reserve. Too much compression to save space will lead to the appearance of squares and artifacts on dynamic scenes.
