Modern Xiaomi smartphones, powered by the MIUI shell or the new HyperOS, are powerful multimedia centers that allow you to create quality content right in your pocket. Device owners often face the need to edit a video for social networks, whether it is Instagram Reels, TikTok or YouTube Shorts, where the audio track plays no less important role than the video. Standard tools of the system offer basic functions, but for full creativity often requires a deeper approach to editing sound.
The process of adding audio on Android devices of the Xiaomi brand can range from simple switching of a track in the gallery to the use of specialized video editors. It is important to understand that the quality of the final file depends on the chosen method and the original parameters of the video file. In this article, we will discuss in detail all the available methods so that you can choose the best option for your tasks.
Don't underestimate the importance of balancing the volume of the original video with the overlay music. If you ignore this aspect, dialogue can become indistinct and background noise can drown out the melody. We'll look at tools that allow you to fine-tune these parameters to achieve professional results.
Use of the built-in video editor MIUI and HyperOS
The first and most affordable editing tool is the built-in Gallery app, which is preinstalled on all Xiaomi, Redmi and POCO smartphones. The developers of the system have implemented a sufficiently functional video editor that allows you to perform basic operations without installing additional software. To start working, you just need to open the desired video, click the "Change" button and select the "Edit video" option.
In the interface that opens, you'll be greeted by a timeline where you can manage the duration and layers. To add music, you'll need to find a note icon or an Audio section. The system will suggest you select a track from the built-in library or from the device's memory, which the built-in editor allows you to add several tracks, but their number is often limited.
⚠️ Note: When using the built-in editor, make sure that the format of your video file is supported by the system for export, otherwise the saving process may result in an error or conversion to a lower quality.
Special attention should be paid to the function "Loudness of the original." If you overlay background music, often you need to completely remove the sound from the original video or significantly reduce its level. Adjustment slider allows you to do this smoothly, creating a fading effect.
💡
If the built-in editor doesn't see your audio file, check its format. The most versatile are MP3 and AAC.
After setting all parameters, you need to save the project. The system will suggest selecting resolution and frame rate. It is recommended to choose parameters identical to the source to avoid unnecessary compression and loss of image detail.
Third-party applications for professional installation
For those who don't have enough of a standard gallery, Google Play offers a lot of powerful solutions, including CapCut, InShot and KineMaster, which offer multi-track editing, allowing you to overlay music, voice commentary and sound effects at the same time, and multi-tracking is a key advantage for complex editing.
Consider the popular CapCut editor, which is perfectly optimized for the Snapdragon and MediaTek processors used in Xiaomi smartphones. Once you import the video onto the timeline, you can add an audio track by selecting the source of "Sound" or "Extracted from video" and this gives you the flexibility to choose the material.
- 🎵 Track Library: A huge selection of free music and sound effects within the app, sorted by genre and mood.
- 🎚️ Key shots: Ability to automate volume change, creating smooth appearance and attenuation of music without jerking.
- 🎤 Voice recording: The voice recorder feature allows you to voice video directly in the application, synchronizing speech with a video sequence in real time.
- 🔊 Noise Reduction: Advanced algorithms for cleaning audio from background noise, which is critical for conversational videos.
It’s important to note that some features in third-party apps can only be accessed through a paid subscription, but the basic functionality is usually enough to create quality content for social media. Free versions often add a watermark at the end of a video, which can be easily removed manually in the same editor.
Removing the original sound and replacing the track
Often, the original sound of a video contains wind noise, extraneous conversations, or simply poor quality recording, in which case the most appropriate solution would be to completely shut down the original track. In most editors, including the one built into MIUI, this is done through the Loudness menu, where the slider "Original" is translated to zero.
If you need to replace the sound but leave some of the sound behind (e.g., cut only noisy areas), you need to do a little more work, use the Split function on the audio track to cut the sound in the right places, and remove unwanted segments, and then you can overlay the music track into the space that has been vacated.
| Method | Preservation of the original | Sound quality | Difficulty |
|---|---|---|---|
| Total shutdown | No. | High (new music only) | Low. |
| Volume down. | Yeah (quietly) | Medium (mixture) | Low. |
| Cutting fragments | Partially. | High. | Medium |
| Overlaying | Yeah (loudly) | Depends on the mix. | Tall. |
When replacing a track, it is critical to keep synchronization: the music should be in the rhythm of the change of frames or actions on the screen. To do this, use timeline zooming to see individual frames and accurately position the beginning of the music track.
Work with audio formats and file library
Xiaomi smartphones support a wide range of audio formats, however, MP3, AAC and WAV remain the most preferred for video editing. AAC format provides better quality with a smaller file size, which is important for mobile devices with limited memory. WAV is used if maximum quality is required without compression, but such files take up a lot of space.
When importing music from the file manager MIUI HyperOS or make sure the file is not protected DRM-Files downloaded from streaming services (for example, offline tracks Spotify or Yandex.Music) often have special extensions and can not be used in third-party video editors.
Where do you store music for editing?
It's convenient to use a built-in Music app or file manager to organize your library, structuring folders by genre or project makes workflow much easier, and it's also worth remembering (copyrights) if you plan to publish videos in the public domain.
Volume setting and audio effects
Just overlaying music is not enough, you have to put it right in the video, and a sharp start can ruin the video, and use Fade In at the beginning and Fade Out at the end of the video, which is a standard technique that makes editing professional.
If there is speech in a video, the music should be quieter so as not to interrupt the voice. The optimal level of background music when there is a conversation is -15 dB...-20 dB relative to the main sound. Many modern editors have a function called Auto-Ducking, which automatically reduces the volume of the music when speaking.
- 🔊 Normalization: Aligning the volume of the entire track to a single level so that quiet areas are audible and loud areas do not cause distortion.
- 🎼 Equalizer: Frequency adjustment (bass, medium, high) for better mixing of music with voice.
- 🎧 3D Audio: Some editors allow you to simulate spatial sound, which adds depth to the perception.
⚠️ Warning: Do not set the overall volume of the video to a maximum (100% or higher), as this will lead to clipping (distortion of sound), and listeners will be unpleasant to hear wheezing in the speakers.
Video export and quality preservation
The final step is saving the project. When exporting video to Xiaomi, it is important to choose the right output parameters. For social networks (Instagram, TikTok), the optimal resolution will be the best one. 1080p upon 30 or 60 The bitrate video should be set in the range 10-15 Mbps for balance between quality and file size.
As for audio, when exporting, choose an AAC codec with a bitrate of at least 128 kbit / s, and preferably 192 kbit / s or 256 kbit / s. This will provide clean and rich audio. Higher audio bitrate values are rarely visible on mobile speakers, but increase the weight of the file.
☑️ Checklist before export
The rendering process can take time depending on your Xiaomi CPU power and video length, and it is not recommended to switch to heavy apps or games during this process so that the system can devote maximum resources to encoding videos.
💡
The right choice of bitrate and codec when exporting is more important than the original resolution, as this directly affects the compatibility of the file with social media players.
