How to Add Track to Music on Xiaomi Phone: From Standard Tools to Professional Apps

Adding a music track to a video or audio file on Xiaomi smartphones is a challenge faced by both beginners and experienced content creators. Depending on the purpose (modeling for TikTok, creating a podcast, making a video), approaches can be radically different from built-in MIUI features to third-party applications with advanced capabilities. The main problem is to figure out which tool is right for you, given the firmware version, the device model (Redmi Note 12, Poco X5, Xiaomi 13T) and the required level of quality.

In this article, we’ll break down 5 proven ways to add a track to your music or video on Xiaomi, including:

  • 🎵 Built-in tools MIUI (application-free)
  • 📱 Popular Mobile Editors (CapCut, KineMaster)
  • 💻 Professional solutions for synchronization of sound and video
  • 🔄 Bypassing restrictions on the duration of the track in social networks
  • ⚙️ Customization of bitrate and output file format

Special attention will be paid to the hidden features of the Gallery app in MIUI 14/15, which allow you to overlay music on video without losing quality – this feature often goes unnoticed even by experienced users.

Starting with MIUI 12, the standard Gallery app (com.miui.gallery) has a basic video editor that supports audio overlay, ideal for quick editing without installing third-party software.

To add a track:

  1. Open the Gallery and select the video.
  2. Click "Edit" (Icon) 🖊️ bottom-screen).
  3. Go to the Music tab (note) 🎵).
  4. Select a track from the list of suggested ones or click Add Music to download your file (.mp3,.m4a,.wav formats are supported).
  5. Adjust the volume of the original sound and superimposed track with sliders.
  6. Save the video with the "Done" button.

Make sure the video is MP4 or MOV| Check the length of the track (maximum 10 minutes in MIUI 14)| Turn off the original sound if you don't need it |Save backup of the original file

⚠️ Note: In some regional versions MIUI (For example, in India or Europe, there may be no Music tab, in which case update the Gallery app via Google Play or use alternative methods from the following sections.

MIUI versionMax. Track durationSupported sound formatsMax. Video resolution
MIUI 12–135 minutes.MP3, M4A1080p
MIUI 1410 minutes.MP3, M4A, WAV4K (with compression)
MIUI 15 (beta)15 minutes.MP3, M4A, WAV, FLAC4K (no compression)

If the built-in editor doesn’t save the video with the overlaid track, try renaming the track file to Latin (without Cyrillic and characters) and try again.

2. Method: CapCut application - professional installation

CapCut by ByteDance (TikTok developers) is one of the most popular mobile editing solutions, supporting multi-track audio overlay, synchronization effects, and watermark-free export.

Instructions for adding a track:

  1. Install CapCut from Google Play or AppGallery.
  2. Create a new project and import the video.
  3. Click Audio → Add Sound and select a file from the device or from the CapCut library.
  4. Drag the audio track to a timeline under the video.
  5. Use the Synchronization tool» (🎯), to fit the track to the key moments of the video.
  6. Export the project with settings: 📌 Permission: 1080p or 4K (Xiaomi 13 Ultra) 📌 Bitrate: 8-12 Mbps for balance of quality and size 📌 Format: MP4 (H.264) compatiblely

⚠️ Note: When exporting to 4K Lags are possible on devices with 6 GB of RAM (for example, Redmi Note 11). In this case, reduce the resolution to 1440p or close the background applications.

How to remove the watermark in CapCut?
The official version of CapCut doesn't add watermarks, but if you use modified APKs, a sign may appear.To remove it: 1. Export watermarked videos via the web version of CapCut on PC. 2. Or trim the video edges in another editor (like VivaVideo) if the sign is located at corners.

3. Method: KineMaster - for multi-track mixing

KineMaster stands out among mobile editors with support for multiple audio tracks, which is useful for creating podcasts or complex compositions. For example, you can overlay voice commentary over a music track and sound effects.

Step-by-step:

  1. Download KineMaster and create a new project.
  2. Import the video to the main track.
  3. Add the audio file through the “Layer” button → “Audio”.
  4. Adjust the volume of each layer separately (double touch on the track → “Loudness”).
  5. Use the "Pruning" tool» (✂️), to sync the track with the video.
  6. Apply transition effects (such as Fade In/Out) to smoothly start and end the track.

How to transfer files from Xiaomi to PC:

  1. Connect your phone over USB in File Transfer (MTP) mode.
  2. Copy the video and audio files into a folder on your computer.
  3. Import them to the selected program and perform installation.
  4. Export the project in MP4 format (H.265) for minimal quality losses.

⚠️ Note: When working with video in resolution 8K (For example, with Xiaomi 13 Pro, make sure your PC meets the requirements:

  • 🖥️ Processor: Intel i7/Ryzen 7 higher.
  • 🖥️ RAM: 16 GB or more.
  • 🖥️ Video card: NVIDIA RTX 2060 or similar.

Tips for Syncing Track and Video

Even after overlaying a track, the video may look unprofessional due to the mismatch between sound and image.

1.Use time stamps

Before editing, make a list of key moments of the video (e.g., change of frames, actions) and mark the corresponding timestamps in the audio file.

0:00 – 0:05: Introduction (quiet background)




0:06 – 0:12: Peak of action (loud music)




0:13 – 0:18: Attenuation (smooth decrease)

2. Adjust the sound delay

In CapCut or KineMaster, you can manually shift the audio track by milliseconds to sync it with the video, for example, if the track is 0.3 seconds ahead of the picture, move it to the right on the timeline.

3. Apply the Ducking effect

This effect automatically lowers the volume of background music when the video is spoken, and in KineMaster it's called Ducking and is in the audio track settings.

💡

For perfect synchronization, use the Frame-Attached feature in CapCut: Hold your finger on the audio track and drag it until the sound matches the motion on the video.

Frequent Mistakes and How to Avoid Them

Even experienced Xiaomi users face problems overlaying tracks, and here are the most common mistakes and solutions:

Problem.Reason.Decision
Track cut off on exportLimitation of duration in the free version of the editorBreak the video into parts or use CapCut Pro
Video and sound are not synchronizedWrong bit stream or FPSSet the same FPS for video and project (e.g. 30 FPS)
Low quality of sound after exportToo low bitrate audioSet the bitrate to at least 192 kbps in the export settings
The app flies out when renderingLack of RAM or overheating of the processorClose the background applications and cool the device (remove the case)

⚠️ Note: On Xiaomi devices with MediaTek processor (e.g. Redmi) 10C) If you render video longer than 5 minutes, you may have a code not supported error, in which case export the project piece by piece or use a PC.

Can I add a track to a video right in the Camera app on Xiaomi?
No, the Camera app (com.android.camera) in MIUI It does not support audio overlay after shooting. However, you can turn on background music while recording in Short Video mode (available on Xiaomi 12 and later). To do this, open Camera and go to Short Video mode. Click on the Note icon. 🎵 You can choose the track from the one you've got, or you can download your own. Start recording, and the music will be played in real time. ⚠️ Note: The original sound from the microphone will be mixed with the track and cannot be separated during editing.
Why does the video become “twitchy” after adding a track?
This problem is related to the mismatch between the FPS (frames per second) of the original video and the project. For example, if the video is shot at 60 FPS and the project in the editor is set to 30 FPS, the frame will “skip.” Solution: In CapCut: go to the project settings → set the FPS corresponding to the original video. In KineMaster: click on the video on the timeline → “Spe” → select “Use the original FPS”.
How to add a track to a video longer than 15 minutes?
The built-in MIUI tools and most mobile editors limit the duration of the project. For long videos: Break the video into 10-15 minutes with Video Splitter (available on Google Play). Add the track to each part separately. Glue the finished pieces in one project (for example, in CapCut). Alternative: use desktop programs (Adobe Premiere, Shotcut), which have no strict duration restrictions.
Can I add a track to an audio file (e.g., overlay a voice to music)?
Yes, audio editors are good for that: 📱 Lexis Audio Editor (for Android) – supports multi-track mixing. 📱 BandLab – Cloud Editor with Effects (Reverb, Equalizer). 💻 Audacity is a free plug-in program. Instructions for Lexis Audio Editor: Import the main track and voice recording. Place the tracks one above the other on the timeline. Adjust the volume of each track separately. Export in format MP3 or WAV.
Why is the video not playing on other devices after adding a track?
This problem arises from: 🔹 Incompatible codec (e.g., incompatible codec, H.265 It is not supported by old TVs). 🔹 A damaged file during export (often when the process is interrupted). 🔹 Restrictions DRM (Solution: Export the video in format MP4 (H.264) Check the video on another device before posting. If the track is downloaded from YouTube, use legal sources (e.g. Epidemic Sound).
