Xiaomi Redmi 9 is one of the most popular budget smartphones, which is still actively used due to balanced features and support for updates. However, many owners are faced with the question: how quickly and without loss of quality to crop video right on the device?
In this article, we will discuss three main ways to clip videos on Redmi 9: through the standard Gallery app, using the built-in Video editor from Xiaomi, and using third-party applications for those who want more features. Special attention will be paid to preserving quality, optimizing files for social networks and the nuances of working with different formats (MP4, MOV, 3GP).
Method 1: Cutting video through a standard gallery
The easiest and fastest method is to use the built-in Gallery app, which is the default on all Xiaomi smartphones, which is suitable for basic cropping: removing unnecessary fragments at the beginning or end of the video, and splitting the video into parts.
To clip the video through the Gallery:
- Open the Gallery app and find the video file you want.
- Slip through the video to open it on the full screen, then click on the Edit icon** (usually it looks like a pencil or scissors).
- At the bottom of the screen, you'll see a timeline with two sliders, left (beginning) and right (end), and move them around to highlight the desired snippet.
- Click Save or Ready – The clipped video will be saved as a new file (the original will remain intact).
⚠️ Note: The Standard Gallery on Redmi 9 does not support clipping above Full resolution HD (1080p). If your file has permission 4K or high bitrate, the application may give an error or save the result in a reduced quality, in which case it is better to use specialized applications (see Method 3).
💡
If the video is “slowing down” after clipping, try saving it in MP4 format with a bitrate of no more than 10 Mbps. To do this, select the “Optimize for the Web” option before saving (if it is in your version of MIUI).
- ✅ Pros: Quickly, without installing additional programs, saves the original.
- ❌ Cons: Limited functionality (no ability to crop the middle of the video, add transitions or filters).
- ⚙️ Nuance: On some versions MIUI Video editing option hidden behind a long tap on file.
Method 2: Using the built-in Video Editor
Xiaomi has another standard app, Video (sometimes called MiVideo or Video Editor), which offers a little more features than the Gallery, including cropping the middle of the video, adding music and simple effects. This editor is pre-installed on Redmi 9, but if it is not available, you can download from GetApps (the Xiaomi store).
Instructions for pruning:
- Open the Video app and import the file you want (click + or Create a project).
- On the timeline, select the fragment you want to remove (slip on the beginning and end of the unnecessary segment).
- Click on the Scissors or Separate icon to break the video into pieces.
- Remove unnecessary segments by clicking on the cart, then connect the remaining fragments.
- Click Export and select quality (Original or High is recommended).
⚠️ Note: When exporting a video via MiVideo to Redmi 9, the MiVideo watermark may appear. To remove it, go to the export settings before saving and turn off the Add Watermark option (if it is active). In some versions of the application, this feature is not available – in this case, use third-party editors.

| Start/end trimming | ✅ | ✅ |
| Removal of fragment from the middle | ❌ | ✅ |
| Adding music | ❌ | ✅ |
| Exports in 4K | ❌ | ⚠️ (depending on the version MIUI) |
| Watermark | ❌ | ✅ (can be turned off) |
Method 3: Third-party applications for professional pruning
If you need more than just removing extra footage — such as overlaying transitions, color adjustments, or exporting without loss of quality — you should pay attention to third-party editors. Redmi 9 will suit both lightweight applications (such as InShot or CapCut) and more advanced ones (such as KineMaster or VivaVideo).
We recommend CapCut, a free editor from ByteDance (TikTok creators), which is optimized for weak smartphones and supports video export in resolution up to 4K without watermarks.
- Download the app from Google Play or GetApps.
- Import the video by tapping on the new project.
- Move the sliders on the timeline to highlight the desired fragment.
- Click Share to remove unnecessary parts, or use the Cut tool.
- In the export menu, select Resolution: Original and Bitrate: High.
⚠️ Note: When working with video in resolution 4K On Redmi 9 (which has only 3-4 GB of RAM), CapCut can slow down. To avoid crashes, close all background apps and export videos piece by piece if it lasts more than 5 minutes.

Optimizing video after cropping: format, size, quality
Cutting down video is only half the battle, and to make sure that the final file takes up little space, loads quickly on social media, and doesn't lose quality, you need to adjust your export settings correctly. This is especially true on Redmi 9, because the smartphone doesn't have much performance when working with heavy files.
The main parameters that should be paid attention to:
- Resolution: 1080p is enough for Instagram and VK, 1440p or 4K is enough for YouTube (if the original is of this quality).
- Bitrate: Optimal – 8-12 Mbit / s for Full HD and 15-20 Mbit / s for 4K.
- MP4 (H.264 or H.265) is the most versatile format.
- FPS: Keep the original frame rate (usually 30 FPS or 60 FPS).
If the video is too heavy, you can compress it without any noticeable loss of quality.
- Open the Gallery app and select cropped video.
- Tap to share. → Optimize (or compress).
- Choose for messengers (strong compression) or high quality (moderate compression).
💡
For videos longer than 10 minutes on Redmi 9, it is recommended to use an external editor on your PC or a cloud service (such as Clipchamp) to avoid overheating your smartphone.
Frequent problems and their solutions
When you crop video on Redmi 9, users often encounter common mistakes: the app crashes, the video is saved without sound or artifacts, and sometimes the process just hangs, and let's take a look at the most common problems and ways to solve them.
Problem 1: Videos are saved without sound.
- ✅ Solution: Check if the sound in the original file is turned off. If the problem persists, try saving the video in a different format (for example, instead of using the original file). 3GP choose MP4).
- ✅ Alternative: Use the App MX Player to extract the sound separately, then overlay it again in the editor.
Problem 2: The app is dropped when exported.
- ✅ Solution: Close all background apps and try exporting the video piece by piece (e.g., split it into 2-3 snippets).
- ✅ Reason: Redmi 9 has only 3-4 GB of RAM, and when processing heavy files, the system can kill the process.
Problem 3: The clipped video is “tearing” or slowing down.
- ✅ Solution: Before cropping, convert the video to MP4 with a bitrate not higher than 10 Mbit / s (you can use HandBrake on PC).
- ✅ Alternative: Save video with lower resolution (e.g, 720p instead 1080p).
⚠️ Note: If video is not played on other devices after cropping, check the codecs. Redmi 9 sometimes saves files in format HEVC (H.265), It's not supported by old TVs or players, so save the video in this case. H.264.
Tips for speeding up the pruning process
Cutting down a video on a budget smartphone can be time-consuming, especially if the file is large. Here are some life hacks to help speed up the process:
- 🔋 Charging: Connect your smartphone to charging before you start editing – this will prevent performance decline due to energy saving.
- ❄️ Cooling: If the Redmi 9 starts to warm up, take a 5-10 minute break or lower the brightness of the screen.
- 🗃️ Memory: Transfer the video to a memory card (if any) – this will unload the internal drive.
- 🔄 Cash: Periodically clear the cache of Gallery and Video apps in the settings.
If you often have to edit videos, consider using cloud services like Clideo or Kapwing, which allow you to crop video directly in the browser without loading your smartphone, minus you need a stable Internet.
💡
To speed up rendering in CapCut, disable Hardware Acceleration in the app settings before exporting. Paradoxically, on weak smartphones, this sometimes helps avoid lags.
