Modern smartphones like the Xiaomi Redmi 9 have become powerful multimedia centers that allow you to create quality content right in your pocket. Photo processing and editing videos no longer require expensive computers or sophisticated professional equipment. Owners of Android devices can turn static images into a dynamic presentation or a touching video in minutes using only fingers and screens.
In this article, we will discuss how to make videos from photos with music on your phone for free, focusing specifically on the interface and capabilities of the MIUI system. You will learn about the hidden features of the standard gallery, which are often ignored by users, and also get acquainted with alternative methods if the built-in functionality seems insufficient for the implementation of creative ideas.
The video creation process on Redmi 9 is optimized for fast work even with the less powerful processor of this model, and we will look at the nuances of resolution selection, compression formats and adding audio paths to make the final file look professional and take a reasonable place in the memory of the device.
Using the built-in MIUI gallery for quick installation
The easiest and most affordable way to create a video is to use the regular Gallery app, which is preinstalled on every Xiaomi smartphone. The developers of MIUI have implemented a powerful video editor directly into the photo viewing interface, which allows you not to install additional software. To start work, you need to select the desired photos in the album and click on the “Create” or “Edit” button in the lower menu.
Once you have selected the video mode, the system will offer several pre-made templates with different transitions and music, but for complete control of the process, you should choose the option “Free editing” or similar, where you control the duration of each frame. The editor interface is intuitive: the timeline is located at the bottom, and the editing tools are on the sides or on the top of the screen.
Importantly, the built-in editor automatically adjusts the resolution of the video to the screen settings of your Redmi 9. You can add text signatures, stickers, and even change the playback speed of individual fragments. Export of the finished project takes place in the background, allowing you to continue to use the phone in parallel.
- 📸 Select 2 to 100 photos in the gallery to start the project.
- 🎵 You can select a music track from the built-in library or download your own file.
- ✂️ The duration of each slide is regulated by dragging the boundaries on the timeline.
- 💾 The finished video is saved to the Video folder in the internal storage.
💡
Use horizontal screen orientation when shooting your source photos if you plan to watch videos on TV, although the vertical format (9:16) is ideal for social media Stories.
Setting up music and audio formats
Music is the heart of any video, setting its rhythm and mood. On Xiaomi Redmi 9, you can use tracks stored in your phone's memory or download them from cloud services. The standard video editor supports popular audio formats like MP3 and AAC, which ensures compatibility with most files.
When adding music, it is important to consider volume balance. If there is original sound in the photos (such as video fragments), it can be muted or completely turned off so that the musical background is clearly heard. Auto Fading is often available in the audio track settings, which makes a smooth transition at the end of the video.
⚠️ Warning: Make sure that the music you use is not copyrighted if you plan to post videos on social media to avoid blocking content or disabling the sound by the platform.
For fine-tuning, you can use third-party equalizer apps before downloading a track to the editor, although the built-in MIUI tools are quite good at basic volume normalization. It is also worth checking whether the track is cropped abruptly at the beginning or at the end, as this can spoil the viewing experience.
Application of third-party applications for advanced functionality
If the standard gallery isn’t enough, Google Play offers a plethora of free Android solutions, with leading apps like InShot, CapCut or KineMaster providing professional editing tools, layering and advanced transition effects.
Installing such programs on Redmi 9 is standard, but it is worth paying attention when granting permissions. Apps need access to media files, a microphone (to record voice over video) and storage. Free versions often have watermarks, which, however, in many cases, can be removed by watching an in-app commercial.
The advantage of third-party software is that it has a huge library of effects, filters, and keyframes, so you can animate text, create a picture-in-picture effect, and use a chromakey, which makes your smartphone a full-fledged video studio.
- 🎬 Multilayer: the ability to overlay photos on the photo and add stickers.
- 🔊 Voice recording: voice recorder function for voiceover of slideshow in real time.
- 🌈 Filters: Using Color Corrections to Style All Photos.
- 📤 Export: Choice of quality from 480p before 4K depending on the screen's capabilities.
Technical parameters and optimization of export quality
When creating videos on Xiaomi Redmi 9, it is critical to properly configure export options to maintain a balance between picture quality and file size. The Helio G80 processor installed in this model is capable of processing video at 1080p resolution at 30 frames per second without significant delays.
The choice of bitrate affects the detail of the image. For social networks such as Instagram or TikTok, a bitrate of about 5-8 Mbit / s is enough, whereas for viewing on a large screen it is better to set a value of 12-15 Mbit /. Too high settings can lead to the fact that the video will slow down when playing on weak devices.
| Parameter | Recommended value | Description of the impact |
|---|---|---|
| Permission | 1920x1080 (Full HD) | Best for Redmi 9 screen and social networks |
| Frequency of personnel | 30 FPS | Standard smoothness, less load on the processor |
| Format | MP4 (H.264) | Maximum compatibility with any device |
| Bitreit | 8000 kbps | Good quality with reasonable file size |

Working with memory and storing finished projects
Video files take up significantly more space than photos, so owners of Redmi 9 with a storage capacity of 64 GB should carefully monitor the free space. One minute of high-quality video can weigh from 50 to 150 MB. It is recommended to regularly clean the folder "Basket" in the gallery after saving important projects.
MIUI has a built-in Cleanup tool that helps you find duplicate videos and large files, and it’s also helpful to set up automatic sync with Google Photos or the Mi Cloud so that original images can be removed from the device, making room for new creations.
When you actively create video content, the phone can get hot because the video encoding process involves all the cores of the processor. That's normal, but if the device gets too hot, it's worth taking a break or removing the case for better heat sink.
- 🗑️ Clean up video editor cache regularly, which can grow to gigabytes.
- ☁️ Use cloud storage to archive your high-resolution source photos.
- 📱 Close background apps before rendering video to speed up the process.
⚠️ Warning: Do not interrupt the process of saving (rendering) video, even if the phone seems to be getting stuck. Interrupting can damage the file and inability to open it.
