Creating videos on a smartphone has gone from a rare entertainment to an everyday necessity for millions of users. Owners of the popular Xiaomi Redmi Note 8 Pro model often wonder how to improve their recordings by adding a suitable audio sequence to them. Modern mobile processors allow you to process high-definition video files directly on your device without requiring a powerful computer.
The process of overlaying the audio track can range from simply replacing the original sound to complex mixing of multiple tracks. The MIUI operating system that runs your phone already has basic editing tools, but they are not always obvious to beginners. There are also many third-party applications that extend the creator’s capabilities to the level of professional studios.
In this article, we will take a look at all the available ways to work with audio and video content, learn how to use an embedded video editor, what third-party apps to install from Google Play, and how to avoid common mistakes when saving a finished file.
Use of the built-in video editor MIUI
Xiaomi smartphones are equipped with a pre-installed gallery that hides powerful functionality for basic editing. To get started, you don’t need to download additional software, just open the standard Gallery app. This solution is ideal for quick processing, when you just need to add background music or replace the sound.
To start, open the video file you plan to edit and click on the Change button (usually it looks like a slider or pencil). In the menu that appears, select the Audio or Music tab, where the system will prompt you to select a track from the device or application library memory.
The editor interface allows you to drag and drop the audio track along a timeline, cutting the beginning and end of the audio track, and you can also adjust the volume of the original video and the added music separately, creating a fading effect or focusing on certain points.
It is important to note that the built-in tool retains the original recording quality, unless you use aggressive filters. Once you finish editing, click Save and the system will create a copy of the file, leaving the original intact.
- 🎵 Quick access to the media library without leaving the gallery
- ✂️ Accurate clipping of audio and video tracks with a finger
- 🔊 Separate volume control of video and music
- 💾 Saving the result in the original resolution
💡
When using the built-in editor, make sure that there is free space on the phone equal to the size of the original video, otherwise the saving process may be interrupted.
Top apps for installation on Android
If you don't have enough of a standard gallery, you should turn to specialized apps. Google Play offers dozens of solutions, but the Redmi Note 8 Pro, with its screen and performance, is best suited for optimized editors. They provide multi-track editing, keyframe work and extensive effects libraries.
One of the market leaders is CapCut, which offers an intuitive interface and powerful processing algorithms, and users value it for its lack of default watermarks and the availability of automatic music synchronization with video.
Another popular choice is InShot, which is famous for its easy controls and excellent capabilities for creating content for vertical screens of smartphones. Here it is easy to add text, stickers, other effects between clips.
For more advanced users who want to have full control over each pixel and hertz of sound, KineMaster is a good fit.This application provides an interface reminiscent of professional PC programs, allowing you to work with multiple layers of video and audio at the same time.
Step-by-step: Adding a track to CapCut
Consider the process of adding music using the CapCut app, as it is most popular among Xiaomi owners. After installing and launching the program, create a new project by clicking on the large button "New Project" and selecting the video from the gallery.
After you upload the clip to the editing table, look for the audio button in the bottom menu. Click on it and select the "Sounds" option to go to the track library, or "Extracted" if you want to use the sound from another video.
If your music is in the phone files, select the Local or Files tab, find the right track and click + to add to the timeline.The track will appear below the video row and you can move it by squeezing your finger.
To fine-tune your rhythm, use the "CPLIT" function to cut audio or video in the right place. Double tapping on the audio track will open up additional settings, including noise cancellation and echo effects.
☑️ Checklist before video export
Working with multiple audio tracks
Creating complex video content often requires layering multiple sound layers at once, such as a voice speaker or sound effects on the background music, and unlike simple editors, advanced applications allow you to add an unlimited number of tracks.
To add a second track, just repeat the audio addition procedure by selecting a new track, and on the timeline they will be displayed in parallel, so you can move them relative to each other to create the desired rhythmic pattern.
Special attention should be paid to mixing volume, and if the music is playing and the person is speaking, the volume of the music should be reduced to 10-15% so that the voice is clearly heard, and in the application this is done through the Loudness menu for each track separately.
Also available is the Fade in/Fade out feature, which makes the input and output of sound smooth, avoiding sharp cliffs. This is critical to creating a professional experience of watching your video on the Redmi Note 8 Pro.

Comparison of popular video editors
The right tool depends on your specific tasks and level of training, and to help you decide, we have compiled a comparative table of the main characteristics of popular applications available for your phone model.
| Annex | Difficulty | Watermark | Functional |
|---|---|---|---|
| MIUI Gallery | Low. | No. | Basic |
| CapCut | Medium | Removable | Advanced. |
| InShot | Low. | Removable | Medium. |
| KineMaster | Tall. | Got it (free) | Profi. |
Each of these solutions has its own strengths: The built-in gallery is good for speed, CapCut is good for trending content with effects, and KineMaster is good for serious layering.
Xiaomi users often point out that MIUI interface is perfectly combined with horizontal mode in these applications, which allows you to comfortably mount video, holding the phone with both hands.
Export and preservation of results
The final stage of video creation is the right export. The saving settings will determine how your video will look on social networks and how much space it will take up in the memory of the device. Redmi Note 8 Pro is able to render video in 1080p and even 4K resolution, but this is not always necessary.
When exporting, look for Frame Frequency (FPS) options. For smooth video, choose 60 fps if the source material was shot in this mode. For cinematic effect, you can leave 24 fps or 30 fps.
Bitrate video affects image quality and file size. To upload to Instagram or TikTok, it is enough to have an average bitrate, whereas for YouTube, it is better to choose High or Recommended.
💡
Always choose MP4 (H.264) for maximum compatibility with all social networks and instant messengers.
Once the rendering process is complete, which can take anywhere from seconds to minutes depending on the length of the video, the video will automatically be saved to the gallery, and can now be shared immediately with friends or shared online.
⚠️ Warning: Do not interrupt the video export process or switch to other heavy applications during rendering, this may cause file damage or system freeze.
