Processing video content on mobile devices has ceased to be the prerogative of professional editing stations. Modern smartphones Samsung Galaxy have sufficient computing power to perform complex operations with media files directly in the gallery. Users are often faced with the need to delete an unsuccessful take, cut out an advertisement, or simply shorten the timing, leaving only key moments in the middle of the recording.
In this article we will analyze in detail, how to cut the middle of a video on Android Samsung, using both the standard capabilities of the One UI system and third-party solutions. You will learn how to work with a timeline, maintain original quality, and avoid common mistakes when exporting. Mastering these skills will allow you to quickly prepare content for social networks without using cumbersome software on your PC.
The editing process may vary depending on the version of the operating system and the model of your device. However, the basic principles of working with video streaming remain unchanged for the entire ecosystem Android. We will look at three main approaches, each of which has its own advantages depending on the specific task and the required cutting accuracy.
Using the built-in video editor Samsung Gallery
The fastest and most accessible way of editing is using a pre-installed application Gallery. The developers Samsung integrated a powerful editor directly into the interface for viewing media files, which eliminates the need to download additional software. This method is ideal for simply trimming the beginning, end, or removing the center portion by splitting the clip.
To get started, open the desired video and click on the pencil icon at the bottom of the screen. You will be taken to edit mode where you will see a timeline. To cut exactly the middle, you will need to perform a splitting operation. Move the playback slider to the beginning of the fragment to be deleted and select the tool Divide (scissors icon).
After the first division, move the slider to the end of the unnecessary section and repeat the action. Now you have three segments: the beginning, the middle (which needs to be removed) and the end. Select the central fragment by clicking on it and use the delete button or simply drag it down outside the work area.
- 🎬 The split tool allows you to create an unlimited number of segments on one track.
- 💾 The "Save as Copy" function ensures that the original file remains intact in memory.
- ⚡ Video processing occurs locally on device processor, without requiring an Internet connection.
⚠️ Attention: When saving changes over the original, the previous version of the file will be irretrievably lost. Always use the option to save a new copy if you plan to continue working with the material.
Before starting installation, make sure that there is enough free memory on the device. The process of rendering a new copy of a video may temporarily require twice the size of the original file.
Editing through the Google Photos app
An alternative native solution is the app Google Photoswhich is often pre-installed on Samsung devices or available for download. This editor's interface is minimalist but provides all the necessary features for basic cropping. The algorithm of actions here is slightly different from the native Samsung gallery, but the result is comparable in quality.
Open the video in the application and press the button Edit in the bottom panel. Unlike Samsung Gallery, there is no explicit "Split" button to remove the inside in one pass. You will have to use a combination of trimming edges. First, trim the video, leaving only the first part until the fragment to be deleted, save it, then return to the original and trim the second part.
However, there is a more elegant way in new versions of the software. If your smartphone supports the function Smart cropping, you can use the sliders along the edges of the timeline to accurately highlight the desired areas. By dragging the white markers, you visually define the boundaries of the content you are leaving. The system will automatically cut off everything that is outside the selected area.
Basic filters| Features | Samsung Gallery | Google Photos | Third-party applications |
|---|---|---|---|
| Startup speed | Instantly | 1-2 seconds | Depends on advertising |
| Cutting accuracy | High (by frame) | Average | Professional |
| Save original | Automatic (copy) | Manual saving | Depends on settings |
| Additional effects | Filters, stickers | Transitions, sound, text |
Advanced cropping in third-party applications
If the built-in tools seem insufficiently flexible to you, specialized applications like CapCut, InShot or KineMastercome to the rescue. These tools provide multi-track editing, allowing you to not only cut out the middle, but also replace it with another clip, add transitions or effects. This is the best choice for creating high-quality content for social networks.
In such apps, the process of deleting a fragment is intuitive. Import the video to the timeline, find the desired moment and use the Split (Split) function. Make two cuts: at the beginning and at the end of the area to be removed. After that, click on the isolated segment and click the trash can icon. The remaining parts will be automatically glued together.
The main advantage of third-party software is the ability to preview the result in real time and fine-tune the duration of transitions between glued parts. You can smooth out a sharp jump in the picture by adding a short fade or dissolve, which will make the editing invisible to the viewer.
⚠️ Attention: Free versions of popular video editors often add a watermark to the end or beginning of the video. Carefully check the export settings or use the logo removal functions if available.
☑️ Preparing for complex installation
Fine-tuning and working with the audio track
When cutting out the middle of the video, it is important to take into account not only the video sequence, but also the audio. Drastically cutting audio can result in unpleasant clicks or music cutting out mid-sentence. Advanced editors, including an updated gallery Samsungallow you to adjust volume and apply audio fade-out at seams.
If you remove a section with dialogue or an important sound effect, make sure that the transition between the remaining parts sounds natural. In some cases, it is advisable not just to cut out a piece, but to cover it with background music or a sound effect to disguise the editing. To do this, use the function of adding audio to a second track.
Pay attention to lip synchronization and audio after saving the file. Sometimes, with aggressive compression or fast processing on weak devices, desync may occur. If you notice this problem, try changing the export format or lowering the bitrate in the output settings.
- 🔊 Use the
Fade In / Fade Outfunction to smoothly fade in and out the audio. - 🎚️ Adjust the overall volume so that the audio levels in different parts of the video matched.
- 🎧 Always check the result in headphones before publishing or sending a file.
Why can a video slow down during editing?
If the video stutters when scrolling the timeline, this means a lack of RAM or processor overheating. Try lowering the preview resolution in the editor settings or closing other running applications.
Saving formats and export quality
After editing is complete, it is critical to select the correct saving options. Samsung smartphones by default offer export at the same resolution as the source file, but you can change these settings manually. Selecting the wrong codec or bitrate can lead to loss of quality or excessive file size.
For most tasks, the optimal choice is the format MP4 with codec H.264 or H.265 (HEVC). The latter provides better compression at the same quality, but may not be compatible with older devices or some social networks. If you plan to upload videos to Instagram or TikTok, make sure the aspect ratio matches the platform's requirements (usually 9:16).
The rendering (saving) process can take from several seconds to several minutes depending on the length of the video and the processing power Exynos or Snapdragon in your device. Do not lock the screen or switch to other heavy applications while saving to avoid the process crashing.
⚠️ Attention: Application interfaces and available codecs may be updated with new versions of One UI. If you do not find the described button, check the “Lab” section or the settings of the Gallery application itself.
Choosing the H.265 codec saves disk space up to 50% compared to H.264, but requires more powerful hardware for playback.
Solution common problems when trimming videos
Despite the simplicity of operations, users may encounter a number of technical difficulties. One of the most common problems is an "Out of Memory" error when trying to save a modified file. This happens because the system creates temporary cache files during processing.
Another nuisance is changing the orientation of the video. If the original video was shot vertically and you accidentally rotated the screen during editing, the final video may remain horizontal with black bars around the edges. Always fix the screen orientation before starting work or use the rotation lock button.
If the video stops playing on other devices after cutting out the middle, the file container may have been damaged. Try converting the video to a standard format through online services or using another video player to check the integrity of the data. In rare cases, saving again through another editor helps.
Is it possible to restore the original after saving the changes?
Yes, if you used the “Save as a copy” option, the original remains in the gallery. If you have overwritten the file, recovery is only possible through the recycle bin (if the file was recently deleted) or from a Samsung Cloud / Google Drive backup created before editing.
Why is the “Split” button inactive?
Most often this happens if the video is copyright protected (DRM) or has a specific codec format that the built-in editor does not support for modifications. Try converting the video or using a third-party application.
Does the quality of the video decrease after trimming?
When using the built-in Samsung editor and saving in the same format, the quality is practically not lost, since lossless cutting is often used at the edges. However, resaving the same file multiple times can lead to the accumulation of compression artifacts.
How to cut out the middle of a very long video (more than 1 hour)?
For long videos, the built-in gallery may be unstable. It is recommended to use an application YouCut or CapCut, which are optimized for working with long timelines and have more efficient memory management.
Does the editor support cutting multiple fragments at once?
Yes, you can make multiple cuts and remove multiple non-contiguous sections before final save. Just select unnecessary segments one by one and delete them until only the necessary content remains.
