Modern smartphones like the Xiaomi Poco X3 NFC have evolved into powerful multimedia centers that allow not only high-resolution content to be captured, but also instantly processed. Often, after recording a video, you notice unnecessary movements at the beginning or a long ending that needs to be removed. Cutting out excess footage is a basic skill that every user needs to create concise and attractive materials for social networks or personal archives.
The MIUI operating system that runs your gadget already has all the necessary tools for basic editing built in. You don't have to download heavy third-party programs right away if you just want to remove the extra. The standard video editor offers enough functionality to fram, trim, and even overlay filters. Understanding the principles of how native tools work will save you time and battery power.
In this guide, we will take a closer look at all the ways to edit video streams on a Poco X3 NFC device.We will look at both the built-in gallery features and specialized applications that may be required for more complex tasks.You will learn to maintain original image quality and avoid common mistakes when exporting a finished file.
Using the built-in MIUI gallery for quick pruning
The fastest and most affordable way to change the duration of a video is to use the standard Gallery app, which Xiaomi has implemented a powerful enough editor that hides behind a simple interface. To get started, you just need to open the right video from the Camera or Video album. Note that the interface may vary slightly depending on the version of the MIUI firmware, but the logic of action remains the same.
Once you open the file, click on the Change button (usually the pencil icon or sliders at the bottom of the screen). A timeline will open for you, where the entire duration of the video is visually displayed. By moving the yellow markers along the edges of the scale, you select the start and end moments that will remain in the final file. Anything outside the selected area will be cut off.
Important: when moving sliders, the video is played into previews, which allows you to accurately determine the frame from which you need to start or where to end the action.
💡
Always save the original video before editing, using the Save as a Copy feature to be able to return to the source in case of an error.
When the boundaries are set, the system will suggest saving the changes. You can choose to save on top of the original or create a new file. The second option is preferable, since it leaves the source intact. The rendering process on the Snapdragon 732G processor installed in the Poco X3 NFC is fast enough even for rollers in 4K resolution.
Editing through the Mi Video app
If you don't have a standard gallery, you often have Mi Video on board, a more advanced tool that combines player and editor functions. Once you start the app, go to the My Videos tab, select the file you want, and click on the edit icon, and it's more advanced than the basic gallery.
Unlike just cutting edges, Mi Video allows you to work with multiple clips at once if you import them into a project. However, for the simple task of cropping a single file, the algorithm is similar: select the Cut tool, move the frame and confirm the action. The feature of this application is the ability to preview the applied effects before final saving.
- 🎬 Open the Mi Video app and select a file from the list.
- ✂️ Click on the “Edit” button in the lower interface menu.
- ⏱ Select the “Cut” tool and adjust the duration of the roller.
- 💾 Click Save by selecting the resolution and quality of the output file.
The app allows you not only to cut videos, but also to add subtitles, music and transitions if you decide to create a more complex editing. However, it is worth remembering that using a variety of effects can increase processing time. For simple trimming tasks, Mi Video is a great alternative to the standard gallery, offering more flexible export settings.
☑️ Pre-conservation checks
Fine tuning and framing of the image
Often, you don't just need to shorten the video in time, you also need to change the proportions of the frame, like turning horizontal video into vertical for Instagram Stories or TikTok. Xiaomi's built-in tools allow you to do this, too. In editing mode, find the Crop tool, which allows you to change the aspect ratio and zoom in the image inside the frame.
When you fram a piece of the image, you actually cut it around the edges, zooming in the remaining piece of it to the whole screen. This action reduces the overall resolution of the picture as the pixels stretch or cut off. On a Poco X3 NFC screen with its high pixel density, this may not be very noticeable, but when you watch it on a large TV, the loss of quality will become apparent.
⚠️ Attention: With strong digital zooming, video can become blurry. Try not to cut more 20-30% Images if you want to keep the clarity.
This section also includes rotating and reflecting features, and if you've shot a video in the wrong orientation, the Turn tool will fix it in one click, and all changes are applied in a non-destructive way until they're saved, allowing you to experiment with the composition of the frame without the risk of spoiling the material.
Third-party applications for professional installation
For those who lack standard MIUI capabilities, the Google Play Store offers a variety of solutions, including CapCut, InShot, and KineMaster, which offer layer-by-layer editing, key personnel, and advanced color correction, and any one of which will turn your Poco X3 NFC into a portable editing studio.
The main advantage of third-party software is accuracy. You can cut videos into multiple segments, remove the middle, glue different pieces and add transitions. The built-in gallery usually allows you to only cut the beginning and end, whereas CapCut allows you to cut any fragment from the middle of the video, just by dividing the track into parts.
Let’s look at the main advantages of using third-party software:
- 📱 Working with multiple video and audio tracks simultaneously.
- 🎨 A huge library of ready-made effects, stickers and fonts.
- 🔊 Accurately adjusting volume levels and overlaying sound effects.
- 📤 Automatic adaptation of the format for different social networks.
Why can third-party apps slow down?
It is worth considering that free versions of such programs often add a watermark at the end or beginning of a video, which may require viewing ads or buying a subscription to remove, but it is a necessary investment of time or money to create content regularly.
Comparison of video processing methods on Xiaomi
To make it easier for you to choose the right tool, we have developed a comparison table that will help you understand when to use the built-in gallery and when to turn to third-party solutions, each method has its strengths depending on your current tasks.
| Criteria | MIUI Gallery | Mi Video | CapCut / InShot |
|---|---|---|---|
| Launch speed | Instantly. | Quickly. | Average (resource load) |
| Precision of pruning | Basic | Medium | High (post-frame) |
| Watermarks available | No. | No. | Available (in the free version) |
| Layering | No. | Limited. | Full support |
| Internet requirement | Not required | Not required | Required for effects |
As you can see from the table, for the quick, everyday task of cutting off the extra, there's nothing better than a native gallery: it's stable, it doesn't require Internet, it doesn't consume battery power as much as heavy editors, but you can't do without third-party apps for creativity and complex editing.
Saving the result and file formats
The final step is export. If you save clipped video, the system will offer you to choose quality options. On the Poco X3 NFC, options are available from 480p to 4K. Choosing a lower resolution will significantly reduce the file size, which is important for fast sending through messengers. However, for archival storage, it is better to leave maximum quality.
Notice the file format. Standard Android and MIUI container.mp4 codeced H.264 or H.265 (HEVC). Code H.265 It provides better compression at the same quality, but older devices may not play such files.If you plan to send videos to older TVs or phones, choose compatibility.
The process of saving video in 4K resolution on Xiaomi Poco X3 NFC can take from 30 seconds to several minutes depending on the duration of the source and the filters used.
⚠️ Warning: Make sure there is free space on the internal drive. To save a copy of the video, you need a memory of approximately equal to 20-30% file-size.
Once the process is complete, a new file will appear in the gallery. Check its playback, make sure the sound is synchronized with the video, and the clipping has been exactly along the frame boundaries, and if you like the result, the original file can be deleted or moved to a hidden folder for security.
💡
Use H.264 for maximum compatibility when sending videos to other people, and H.265 for personal storage on modern devices only.
