Modern Xiaomi, Redmi and POCO smartphones are equipped with high-quality cameras that allow you to shoot videos in 4K resolution. However, often after recording, you need to remove unnecessary frames at the beginning or end of a clip to leave only the most important moments. The built-in tools of the MIUI and HyperOS operating system offer powerful tools for basic processing of media files without installing third-party software.
The editing procedure may be required to create content on social networks or simply to save the memory of the device. Removing unnecessary snippets is the first step to professional editing, available to every user. Next, we will discuss in detail all available methods, from standard gallery functions to advanced third-party solutions.
It's important to understand that framing the timeline right can reduce the amount of data you take up, and this is especially true for models with little internal memory, and timeline skills are a key skill for today's mobile user.
Use of the built-in video editor in the Gallery
The fastest way to remove the extra is to use the regular Gallery app, which is preinstalled on all devices of the brand. This method does not require an Internet connection or download additional utilities, which makes it ideal for quick editing. The interface here is as simple and intuitive as possible even for beginners.
To get started, you have to open the file you want to edit, and you have to find the edit button, which is usually represented by a pencil icon or sliders at the bottom of the screen, and then you click on it, and you have to select the edit type that you want to edit, and you want to see the clipping function.
You'll see a timeline with two movable markers at the edges, and you move the left and right sliders, you set new boundaries for playback, and anything outside the selected area will be deleted while you save the result.
- 🎬 Open the Gallery and select a video to edit.
- ✂️ Click on the edit icon (pencil) in the lower menu.
- ⏱️ Move the frames on the timeline to cut off extra seconds.
- 💾 Click Save to write a new version of the file.
It's worth noting that a standard editor often offers a copy-saving feature, which means that the original file remains intact and the modified version is written as a new object, which protects against the accidental loss of important frames during experiments.
⚠️ Note: When you save edited video, make sure that there is enough free space on the device. Even if you delete part, the system can create a temporary file before the final recording, which requires additional memory.
💡
When working with long videos (more than 10 minutes), the save process can take several minutes.Do not close the Gallery app until the operation is completed to avoid corruption of the file.
Precise trimming with Mi Video
The second native tool is Mi Video, which is often the default player, which is slightly more advanced than the gallery, and allows you to work with the timeline in more detail, and it has frame-by-frame mode, which is critical for setting boundaries accurately.
When you start an application, you go to the Tools section or open a file from the recent list right away. The playback control menu also has an edit button, and the feature of this method is that you can preview the result in real time before the final rendering.
Users can choose an aspect ratio if they plan to upload content to TikTok or Instagram Stories. Although the main feature here is cropping, the presence of additional filters and the ability to overlay music makes this tool a versatile harvester for quick processing.
It's important to set the resolution of the output file correctly. If the source is shot in 4K and you cut it for social media, it makes sense to reduce the quality to Full HD (1920×1080) to save space. In the Mi Video export settings, these options are present.
| Function | gallery | Mi Video | Third-party annexes |
|---|---|---|---|
| Speed of operation | Tall. | Medium | Depends on the power. |
| Precision of pruning | Basic | Tall. | Professional |
| Quality preservation | Original | Customizable | Maximum. |
| Watermarks available | No. | No. | There are often (in free versions) |
Mi Video is especially useful when you need to not only cut a piece, but also immediately prepare the file for publication. Built-in compression algorithms work effectively, minimizing loss of visual quality when changing the duration.
Working with timeline: fine-tuning
For those who need surgical precision, there is a timeline setting that is detailed, and in standard applications, when fingers are approached, the screen often scales to allow individual frames to be seen, so that an important part of the action is not cut off or, conversely, an unnecessary pause is left.
Some advanced users prefer to use frame-by-frame scroll mode, which is a mode where video is not scrolled by time, but by specific images, and is the only way to perfectly match the beginning of a clip with a music beat or an important event.
When you're working with timeline, it's important to pay attention to the audio track, and often the visual part is cut right, but the sound is cut off abruptly, and in more complex editors you can see (sound visualization), which helps you make smooth transitions.
- 👆 Use two fingers to scale the timeline.
- 🔍 Close the joint areas for maximum accuracy.
- 🎵 Watch for sound visualization to avoid sharp breaks.
- ✅ Always review the results before saving.
If you're working with very long video files, zooming becomes a must. On a small smartphone screen, it's hard to get a look at the entire hour-long video, so zooming helps you focus on a particular second.
The secret to pruning accurately
Pruning through Google Photos and Cloud Services
An alternative to Xiaomi's built-in features is Google Photo, which is installed on most Google-certified devices, with minimalist interfaces and fast and stable cropping, with the main advantage of synchronization with the cloud.
When you open a video in Google Photos, you click on "Change" and select the framing tool. The mechanics of sliders are similar to the system, but the processing algorithms may be slightly different. Often Google Photos is better at saving file metadata.
A feature of this method is the ability to nondestructive editing. You can go back to the original and change the trimming parameters at any time, since the source is often stored in the cloud or hidden folder.
Using cloud services is convenient if you plan to continue editing on your computer or other device, and the cropped snippet immediately becomes available on all gadgets associated with your account.
⚠️ Warning: When using cloud services, make sure you have Wi-Fi sync enabled. 4K-Videos over the mobile Internet can quickly exhaust your plan.
Third-party applications for professional installation
When built-in tools aren't enough, Google Play's customized apps come to the rescue, with CapCut, InShot, and KineMaster leading the way, providing not just cropping, but a full-fledged assembly line with layers, effects, and keyframes.
In these applications, the cutting process is the most flexible, so you can cut the video into multiple parts, remove the middle, glue the different pieces together and change the order, and it's not just cropping, it's creating a new video sequence.
Installing third-party software makes sense if you create content regularly, and allows you to overlay text, stickers, and transitions that you can’t do with a standard Xiaomi gallery.
☑️ Criteria for choosing a video editor
Consider that powerful editors require more CPU resources. On budget Redmi or POCO models, rendering a complex project can take a long time or cause the device to heat up.
Frequent mistakes and problem solving
And in the process of editing, users often face typical problems, and one of them is format mismatch, and if you cut down a vertical video, but you save it in a horizontal profile, you'll see black bars on the sides.
Another common mistake is the loss of quality when you save it again, and every time a video goes through the process of encoding, it can lose in detail, so try to do all the edits in one go, rather than editing the already cropped file again.
There is also a problem with file formats: some old or specific codecs (.mkv,.hevc) may not be properly handled by the built-in tools, in which case the system may offer conversions, which also takes time.
- ❌ Do not edit the same file repeatedly.
- ❌ Avoid sharp breaks of sound at the joints.
- ❌ Don’t ignore warnings about incompatible permission.
- ✅ Always back up the originals before mass editing.
If an editing app crashes or freezes, try clearing its cache in the system settings. Settings path → Apps → Gallery → Memory → Clearing the cache often helps restore health without losing data.
💡
The golden rule of editing is always to work with a copy of the file, leaving the original intact until you are 100% sure of the result.
