Modern Xiaomi and Redmi smartphones have become powerful multimedia centers that allow not only to shoot high-resolution videos, but also immediately process them. Often, the footage contains extra footage at the beginning or at the end, or foreign objects that need to be removed were captured. The built-in capabilities of the MIUI and HyperOS shell provide all the necessary tools for this without requiring the user to install third-party applications.
The framing process on Xiaomi devices is as simple and intuitive as possible, even for beginners. You can easily change the aspect ratio for posting on social networks, align the horizon or simply shorten the duration of the video. The system allows you to work with files of any format supported by a standard video player, while maintaining the original image quality without noticeable losses.
In this article, we will take a look at all the steps of working with video content on your smartphone. We will look at the standard editor, hidden gallery functions and the nuances of exporting the finished file. You will learn how to quickly put your records in order using only the standard tools of Xiaomi system.
Preparing a file and running a standard editor
The first step to get started is to find the right video file in your device's memory. The standard Xiaomi media program is usually called a "Gallery" or "Video." Open the app and find the Camera or Video folder in the album list, where the default recordings from the main camera are saved.
Once you have selected the video you want to edit, you need to start editing mode. To do this, tap the screen to make the control menu appear, and find a button with a pencil or sliders. Depending on the version of the MIUI shell, this item can be located in the bottom menu or hidden under the button "More".
It's important to understand that the built-in editor works with a copy of the file unless you've enabled a special save option on top of the original, which means that the original video recording will remain unchanged, which is a great insurance against random errors.
⚠️ Note: If your device has a default third-party video viewing app, the standard Xiaomi editor may not start. In this case, open the video through the system Gallery, rather than through a third-party player.
The editor interface is divided into several functional zones, and at the bottom of the screen is a timeline, with crop markers on the sides, and the top of the screen is set aside for previews, where you see the results of your actions in real time, and all the tools are ergonomically arranged so that your fingers don't overlap the image while you're working.
Basic trimming: removing excess time
The most common operation is to remove the uninitial and the end frames. You don't need complex tools to do this, you just need the basic timeline functionality. You can touch the timeline area to activate the duration editing mode.
You'll see two white or colored frames at the edges of the horizontal scrollbar. These markers represent the beginning and end of the piece being saved. You need to drag the left marker to the right to cut off the beginning, and the right marker to the left to remove the end of the record. The movements should be smooth, the system automatically sticks to the key frames for convenience.
When moving sliders, the preview screen displays the current frame, allowing you to choose the exact moment of the beginning and end. The accuracy of the crop depends on the duration of the original video: in short videos, the offset step will be smaller, which allows you to achieve high accuracy up to a fraction of a second.
- 🎬 Drag the left slider to set a new playback start point.
- 🎬 Move the right slider to determine the moment the clip is completed.
- 🎬 Use the play button to check the selected segment before saving.
- 🎬 Click the Save button to fix the changes and create a new file.
Once you have decided on the duration, the system will suggest saving the result. Pay attention to the permission setting when saving: by default it corresponds to the original, but in some versions of the firmware you can choose optimization for social networks, which will reduce the weight of the file.
Image frame and change of proportions
Often, you don't just need to cut time, you also need to change the visible area of the frame, which is called cropping or cropping, and this is useful if you want to remove redundant objects at the edges of the frame or change the format of the video from horizontal 16:9 to vertical 9:16 for Stories.
To access these settings, select the "Capacity" or the icon with the right angles crossing, and you will see a grid overlaying the image, and as you move the boundaries of that frame, you choose which part of the picture will remain in the final video and which will be cut off.
The top menu usually has presets of aspect ratios, so you can choose the format for Instagram, TikTok, YouTube Shorts, or leave it at random, and when you choose a particular format, the frame is locked in preset proportions, allowing you to follow the standards of the sites.
Changing the frame area directly affects the resolution of the final file. If you zoom in on the image, the quality can deteriorate as the remaining pixels are software-stretched. Try not to fraternize the video shot in low resolution too aggressively.
Impact of crop on quality
Special attention should be paid to stabilization when framing, so if you cut the edges of a handheld video, you can accidentally remove the area that the software stabilization used to compensate for the shaking, which can result in the frame boundaries "floating", in which case it is better to enable the stabilization function in the settings before the final save.
Turn, reflection and additional edits
In addition to temporal and spatial trimming, Xiaomi's editor allows you to perform geometric transformations. If you shot a video with your phone upside down, or the frame is mirrored (which is often the case with the front camera), these defects are easy to fix.
In the tool menu, find the "Turn" section or the arrow icon, which has 90-degree clockwise and counter-clockwise rotations, and a "Flip" button that changes the image mirrored on the horizontal or vertical axis, which is especially true for selfie videos, where the text on the clothes can read the opposite.
You can also use basic color correction, and although this is not a direct cropping, often after framing, you need to adjust the brightness or contrast, because changing the frame boundaries changes the perception of exposure, filters are available and you can manually adjust the light parameters.
- 🔄 Turning 90 degrees corrects the orientation of the incorrectly shot video.
- 🔄 Mirror reflection makes text readable on the front camera.
- 🔄 Filters help hide exposure flaws after pruning.
- 🔄 Keeping a copy of the original ensures that you don’t lose the source.
All the effects, including the turns and reflections, are rendered simultaneously with the pruning process, which means you don't have to wait for one operation to complete the other to start the next, you create a complete list of changes, and the system applies them at a time when exporting.
💡
If you plan to upload a video with text (subtitles or inscriptions on your clothes), be sure to check if the image is mirrored before posting.
Export settings and saving the result
The final step is to save the edited material, and when you click on Save or Ready, the rendering process begins, and the processor on a Snapdragon or MediaTek smartphone is actively processing the video stream, encoding a new file.
In some versions of MIUI, a quality dialog box appears before saving, so you can leave the "Like in the original" settings to keep the most detail, or choose "Optimized" if you plan to send a file through a messenger.
The process of saving depends on the length of the original video and the power of the device. On flagship models of Xiaomi, 4K video processing takes seconds, on public sector employees it can take a minute or more, and it is not recommended to interrupt this process to avoid damage to the file structure.
| Parameter | Original | Optimized. | For social media |
|---|---|---|---|
| Permission | Reference (e.g. 4K) | Full HD (1080p) | HD (720p) |
| Bitreit | High-pitched | Medium. | Low. |
| File size | Maximum | Reduced by 40-60% | Minimum |
| Export speed | Longer. | Hurry up. | Instantly. |
Once the save is complete, the system will prompt you to share the file or send it to the messenger immediately. The new file will appear in the gallery in the same folder as the original, but will be marked as edited. The file name often contains the date and time of the copy creation.
💡
The choice of export quality directly affects the space occupied in memory. For archival storage, choose the original quality, for forwarding - optimized.
Frequent problems and their solution
Despite the stability of the system, users may encounter difficulties in working with video. One common problem is the message “Not enough memory” when trying to save a clip clip. To render even a short clip, the system requires temporary free space, often exceeding the size of the video itself.
Another problem is desynchronizing audio and video after cropping, which can happen if a variable bitrate (VBR) file is used that is not properly processed by the embedded codec, and in such cases, it is recommended to convert the video to a standard format before editing.
Users also sometimes complain that video is no longer played on other devices (e.g. TV or PC) after clipping, due to a change in the container or codec when exporting, and make sure that when saving, the MP4 format and H.264 codec are chosen.
⚠️ Note: If you have clipped the video and it slows down when playing, try lowering the export resolution.Perhaps the bitrate of the original file is too high for software decoding on this device.
To solve memory problems, clear gallery cache or delete unnecessary files before starting to work with heavy 4K rollers.
☑️ Pre-conservation checks
Using third-party applications for complex tasks
Xiaomi's staff editor is great at basic tasks, but it has limitations, and if you need to cut a snippet from the middle of a video, leave a few scattered chunks, or put on a complicated graphic, there may not be enough built-in tools, so you should turn to specialized apps from Google Play.
Popular editors like VN Video Editor, CapCut or InShot offer multitrack editing, allowing you not just to trim the beginning and end, but to remove any portions of the timeline, gluing the remaining parts without loss of quality (when set up correctly).
Third-party software has the advantage of batch processing and finer bitrate customization, but these applications often require more resources and may contain advertising. MIUI functionality is usually sufficient for quick trimming of the here and now.
- 📱 VN Video Editor – professional tool without watermarks.
- 📱 CapCut is ideal for creating TikTok and Reels-style content.
- 📱 YouCut – Lightweight Editor with Simple Interface for Quick Trimming.
- 📱 Built-in editor is the best choice for speed and no advertising.
The choice between built-in and third-party solutions depends on your goals. For a family archive and quick sending to WhatsApp, there are enough capabilities for Xiaomi. For a video blog or creating commercials, you should install a profile application.
