How to Insert Music in Videos on Xiaomi Phone: Step-by-step Methods

Creating quality video content on Xiaomi smartphones has become commonplace thanks to powerful cameras and an optimized MIUI system. However, for a video to really catch the attention of viewers on social networks, images alone are often not enough. Sound plays a key role in the perception of material, whether it is a dynamic track for a sports video or a background melody for a vlog.

Owners of Xiaomi, Redmi and Poco devices do not need to immediately look for complex third-party solutions, since the basic functionality of the system allows you to perform simple manipulation of media files. Built-in tools offer an intuitive interface that copes with the overlay of the audio track in a few touches. This is especially convenient when you need to quickly edit material and send it to friends or share it in a story without unnecessary body movements.

However, for deeper audio work, overlapping multiple tracks or precise bit synchronization, specialized applications will be required. In this article, we will take a detailed look at all the available methods, from regular tools to professional mobile studios, so you can choose the best option for your tasks.

Use of the built-in video editor Xiaomi

The fastest way to add music is to use the functionality already installed in your Gallery. MIUI and its global version of HyperOS are equipped with a powerful built-in editor hidden in the video processing menu. To start, you just select the desired video in the album and click the "Edit" button at the bottom of the screen.

When you go into edit mode, find a note icon or Music at the bottom of the toolbar, and you can then select a track from your built-in library, add music from your phone files, or even extract the audio track from another video, which allows you to quickly replace the original sound with a better sound or add background.

⚠️ Note: When using the built-in editor, keep in mind that some features may be limited depending on the firmware version and region.If the Music item is missing, try updating the Gallery app via GetApps.

An important advantage of the regular tool is the absence of watermarks while saving the result, which is often found in free versions of third-party programs. You can adjust the volume of the original video and added music separately, creating a harmonious mix. Once you set the parameters, press the save button and the system will process the file, saving it in its original quality.

For users who value simplicity and don’t want to clutter up memory with unnecessary apps, this method is a priority, ideal for quickly cropping videos and adding popular tunes from a list that is automatically downloaded from the cloud or local memory of the device.

Installation through the Google Photo app

If Xiaomi’s standard interface seems uncomfortable or is stripped down in your firmware version, Google Photos, which is pre-installed on most certified devices, offers cross-platform compatibility and stable operation, allowing you to add music to your video without having to download additional software.

The process starts with opening the desired video in the application, and clicking on the Edit button (usually sliders or settings icon), you need to go to the Audio tab, where the interface is minimal: you see the volume scale of the original and the ability to add a new composition from the Google library or smartphone memory.

• 🎵 Open the video in Google Photos and select “Edit».
• 🎧 Go to the Audio section and click Add Music».
• 💾 Select a track from the list and adjust its duration with a slider.
• ✅ Keep a copy so that the original remains unchanged.

One of the strengths of this method is the ability to intelligently select music, although in our latitudes this feature can work in limited ways. More importantly, Google Photos is great at synchronizing volume, automatically lowering the background noise level when the added track starts playing, which prevents sudden swings in sound that often annoy viewers.

In addition, the app allows you to save the history of changes, which allows you to go back to previous versions of editing if the result did not suit you, which makes the creative process safer and more experimental, allowing you to try different musical solutions without risking spoiling the original material.

💡

When editing in Google Photos, always save a copy of the file, rather than overwrite the original to be able to go back to the source.

Professional processing in CapCut and VN Editor

For those who want to create content like TikTok or Instagram Reels, built-in tools may not be enough. CapCut and VN Video Editor apps provide desktop video editors in pocket format, allowing you to work with multiple audio tracks, overlay effects and accurately synchronize on-screen actions with the rhythm of music.

In CapCut, the process of adding music starts with importing video into a project. By clicking on the audio button, you get access to a huge library of tracks, the ability to record voice over video, or import files from your phone's memory. A unique feature is the "Extracted" feature, which allows you to take audio from another video, which is convenient for creating remixes or reactions.

VN Editor offers an even cleaner interface without intrusive advertising and watermarks, where you can work through the sound wave in detail, cutting tracks to the frame, which is critical for lip-sync or dance videos, where the dissynchrone is even in a fraction of a second catchy.

Both apps support keyframes, which allows you to change the volume of music in the speaker, for example, you can make the sound quieter when someone is talking in a video, and louder during action scenes, this approach turns a simple video into a full-fledged video sequence with a thoughtful sound design.

Configuring access rights and working with the file system

A common problem when trying to insert music is the lack of access to files. In modern versions of Android, which are based on Xiaomi and Redmi, security system strictly controls access to storage. If the application does not see your tracks, the problem lies in the permissions.

To fix this, go to your phone's settings. Find the Apps section and select All Apps. Find your video editor (like Gallery or CapCut) in the list and go to App Permissions, where you need to make sure that access to Music and Audio and Photos and Video is enabled.

⚠️ Note: On Android 11 and above, folder access may be limited. If the app doesn't see music, try moving audio files to a standard Music or Download folder, rather than deep nested directories.

The file system should also be considered. The audio file format should be compatible. The most versatile formats are MP3 and AAC. If you downloaded music in FLAC or WAV format, some simple editors may not recognize them, requiring pre-conversion.

It's convenient to use Xiaomi's Files Explorer to manage files, which allows you to quickly sort audio by folder and move it to easily accessible locations. Use file type search to quickly find the right composition among the entire dataset on your smartphone.

Resolving Sound and Synchronization Problems

Even if all instructions are followed, there can be technical difficulties, one of the most common is the desynchronization of sound and video after rendering, which often happens if the original video has a variable frame rate (VFR), which is typical for on-screen recording or video from some game consoles.

In such cases, it is recommended to use a constant frame rate conversion before editing, and problems can be associated with the codec. If after adding music, the video stops playing on other devices, try saving MP4 format with the H.264 codec, which is the most compatible standard.

• 📉 Video slows down: close background applications to free RAM.
• 🔇 No sound: check if the phone is silent and if the media volume is twisted.
• 🎵 Distorted sound: Make sure the audio bitrate does not exceed the speaker or codec capacity.

Another nuance is volume balance, and it's often the added music that override the voices of people in videos, and professional editors have Auto Ducking, but in simple cases, you'll have to manually adjust the volume sliders to make the music quieter when you're speaking.

If you use Bluetooth headphones to monitor sound during editing, remember that a delay in signal transmission can create a false impression of out-of-synchronization. Always check the final file through your phone's speaker or wired headphones before posting.

💡

The golden rule of editing: always check the final file on different devices, as codecs and volume can play differently.

Optimizing the process and maintaining quality

The final step is exporting the finished video, so it's important to keep the image and sound quality in mind for the sake of file size. In export settings (usually the button in the corner of the screen), you should choose the resolution that corresponds to the source. If the video is shot in 1080p, it doesn't make sense to put 4K, it will only increase the weight of the file without improving the picture.

For social networks, the optimal value for video in Full HD will be the range from 8 to 12 Mbit / s. Higher values can lead to the fact that the platform (Instagram, Telegram, WhatsApp) when downloading itself will severely compress the file, worsening its quality.

Also worth considering is the audio format when exporting. Standard is AAC at 44100 Hz or 48,000 Hz. These settings ensure the best compatibility with all modern smartphones and computers, ensuring that your work will be seen and heard by all the recipients.

Remember to clear the video editor cache after big projects are completed. Apps like CapCut or VN can take up hundreds of megabytes of time memory, which is critical for devices with a small amount of internal storage. Regular cleaning ensures that Xiaomi's system is stable.
