Owners of the Xiaomi Redmi Note 9 smartphone often face the need to quickly edit footage directly on the device without using a computer. Modern mobile processors allow you to edit videos in high resolution in seconds, making the process of cropping (crop) available to every user. Removing extra seconds at the beginning or end of recording is a basic skill that helps save memory and make content more dynamic.
The process of editing the MIUI system (or its current HyperOS shell) is as simple and intuitive as possible, even for beginners. You do not need to install heavy third-party applications if you only need a simple clipping of the frame or duration. In this article, we will discuss in detail all the available ways to work with video content on your device.
Understanding the video editor in Redmi Note 9 will open up new possibilities for creativity, not just to remove the redundant, but also to preserve the original image quality, and to export the result correctly. Let's move from theory to practice and look at the tools that you already have in your hands.
Using the built-in MIUI Gallery for quick framing
The most obvious and quick way to change the duration or proportions of a video is to use the standard Gallery app, which Xiaomi has integrated a powerful enough editor right into the media viewer, eliminating the need to run separate software.
Once you start the file, you'll have controls on the screen, and you'll need to find the Edit button, which is usually represented as a slider icon or a magic wand, and clicking on it will put the interface into editing mode, where the basic tools for working with the timeline are available, and here you can see a timeline limited by yellow or white markers at the edges.
By moving these markers left or right, you select the portion of the video stream you want to leave behind, and anything outside the selected area will be deleted when saved, which is ideal when you need to quickly cut out the unfortunate take or leave only the most interesting moment of the event.
- 📱 Open the Gallery app and select an album with a video.
- ✂️ Click on the edit icon in the bottom interface menu.
- ⏱️ Move the sliders on the timeline to select the desired segment.
- 💾 Click Save to create a new copy of the file or replace the original.
It's important to note that the standard editor allows you not only to change the duration, but also to apply simple filters or change the aspect ratio if you plan to download to social networks.
Working with Mi Video Video Player and its Toolkit
MIUI firmware often pre-installed a separate video player called Mi Video, which is positioned not just as a viewer, but as a multimedia combine that includes converter and basic editor functions. The interface here may differ from the gallery, offering a more professional approach to navigating files.
To get started, run Mi Video and find the file you want in the list. Unlike in the gallery, here the editor can be hidden in an optional menu, often designated by three dots or a separate Tools tab. The cropping functionality in this app often works more smoothly with large high-resolution files like 4K or 60 FPS.
⚠️ Note: When using the Save as a Copy function, make sure that the original file remains unchanged and the new one takes up space next to it, which can quickly exhaust available memory.
Once you select the cropping tool, you'll see a similar timeline, and Mi Video's advantage is that it can position frame-by-frame more accurately, which is critical for making neat transitions, and it's also often available to change the format of the frame without losing image quality, which is convenient for adapting horizontal video to vertical Stories.
The rendering process in this application is optimized for the Snapdragon processor installed in the Redmi Note 9. This means that video processing will take a minimum of time, and the device’s battery will not run out too quickly.
💡
If the video slows down when editing, close the background applications through the menu of running tasks - this will free up RAM for smooth operation of the video editor.
Cutting Videos Through Google Photos and Cloud Services
An alternative and often more convenient way to edit is to use the Google Photos app, which is installed by default on most Android devices, including Xiaomi.This method is especially good in that it synchronizes changes with the cloud, allowing you to start editing on the phone and finish on a tablet or PC.
Google Photos is minimal. Open the video, click on the "Change" button (usually these are sliders with settings). In the bottom menu, select the "Capture and Turn" tab, where you can not only cut the duration by dragging sliders on the scale, but also change the geometry of the frame by selecting standard proportions for Instagram, TikTok or YouTube.
The main advantage of this method is non-destructive editing. Google Photos saves the original in the cloud, and all your edits apply only to the displayed version until you decide to save the changes as a new file, which allows you to experiment with cropping as many times as you want without fear of spoiling the source.
Google's algorithms also often offer automatic color stabilization and enhancement that can be applied simultaneously with cropping, making the simple process of removing extra seconds into a full-fledged video retouch, and for users of the Google ecosystem, this is the most integrated and secure option.
Third-party applications for professional installation on Redmi
If MIUI is not enough, the market offers a lot of powerful tools. The Redmi Note 9 with its FullHD+ screen will be great for apps like CapCut, InShot or VN Video Editor.
In these applications, the pruning process (Split and Trim) is more flexible: you can cut pieces from the middle of the video, glue different fragments, overlay music and text. The interface here is sharpened to vertical control, which makes the finger editing on the touch screen as comfortable as possible.
Installing a third-party editor makes sense if you plan to blog or share content frequently on social media, and these apps can work with multiple video tracks, which is not available in a standard gallery, and they often have built-in effects and transition libraries.
- 🎬 CapCut – perfect for TikTok and Reels, has auto subtitles.
- 🎨 InShot – easy to learn, great for creating collages.
- 🎥 VN Video Editor – professional tool without watermarks in the free version.
Why should you avoid “heavy” editors on budget smartphones?
Accurate setting of the frame and changing the proportions
Often, “trimming” is not just about erasing time, but also changing the edges of the image (crop). In Xiaomi Redmi Note 9, this is done through the framing function, this is necessary when an extra object on the edges is in the frame or you need to change the format from 16:9 to 9:16.
In edit mode, select the Crop tool. A grid will appear on the screen to help you follow the rule of thirds. You can move the frame freely or choose presets ready-made: 1:1 for an Instagram post, 4:5 for a tape, or 9:16 for Stories. When changing the proportions, it is important to make sure that key objects are not cropped.
When working with a 2340×1080 screen resolution, it is important to remember the pixel density. Strong digital magnification (crop) can lead to loss of image clarity as the video stretches. Try not to zoom in more than 110-120% if the original quality is not 4K.
Once you select the right area, confirm the action. The system will suggest saving the changes. If you have changed the proportions, the black bars on the sides (if any) will be cut off, and the video will occupy the entire screen when played in the appropriate format.
Results saving and file management
The final step is saving the edited video. Most MIUI editors will offer you two options: Save (rewrite the original) or Save as a copy. The second option is more secure, as it leaves the original file intact.
When saved, the system can offer a choice of export quality. For the Redmi Note 9, the optimal choice will be 1080p with a bitrate of about 10-15 Mbps. This will ensure good quality on the smartphone screen and an acceptable file size. The choice of 4K can be redundant for a small screen and take up a lot of space.
Once the rendering process is complete, the new file will appear in the same folder as the original, often with the label " edit" or " edited" in the title, and you can immediately send it via instant messengers or upload it to the social network.
| Parameter | Recommended value | Influence on the file |
|---|---|---|
| Permission | 1920×1080 (Full HD) | Balance of quality and size |
| Frequency of personnel | 30 FPS | The standard for social media |
| Format | MP4 (H.264) | Maximum compatibility |
| Bitreit | 10-12 Mbps | Optimal for a 1080p screen |
