Many people assume video editing requires complex tools. But trimming is one of the easiest tasks you can do. The Photos app is designed for quick edits like cropping, adding filters, and trimming. It works with MP4 files, which are the most common video format today. You can trim videos recorded on your phone, downloaded from the internet, or captured with your webcam. The process takes less than a minute once you know the steps.
How To Trim A Mp4 Video In Windows 10 Using The Photos App
The Photos app is your primary tool for this task. It is lightweight and does not slow down your computer. Here is the complete step-by-step method.
Step 1: Locate Your MP4 File
First, find the MP4 video you want to trim on your computer. It might be in your Videos folder, Downloads, or Desktop. Right-click the file and select “Open with” then choose “Photos.” If Photos is not listed, click “Choose another app” and select it from the list. The video will open in the Photos app viewer.
Step 2: Access The Trim Tool
Once the video is open, look at the top toolbar. You will see several icons. Click the “Edit & Create” button, which looks like a pencil inside a circle. A dropdown menu appears. Select “Trim” from the options. This opens the trimming interface.
Step 3: Set The Start And End Points
The trim tool shows your video timeline at the bottom. You will see two white circles on the timeline. Drag the left circle to where you want the video to start. Drag the right circle to where you want it to end. A preview window shows the current frame. Use the play button to check your selection. You can adjust the circles as many times as needed.
Step 4: Save The Trimmed Video
After setting your start and end points, click the “Save a copy” button in the top right corner. A dialog box appears asking where to save the file. Choose a folder and give the file a new name. Click “Save.” The trimmed video is created as a new file. Your original video remains unchanged.
Step 5: Check The Output
Open the saved file to make sure the trim is correct. Play it from beginning to end. If something is off, you can repeat the process. The Photos app does not overwrite your original file, so you can try again without worry.
That is the core method for how to trim a mp4 video in windows 10. But there are other ways too. Let us explore them.
Alternative Methods To Trim MP4 Videos In Windows 10
Sometimes the Photos app might not work for your specific file. Or you may want more control over the trim. Here are three reliable alternatives.
Using The Video Editor App
Windows 10 also includes a Video Editor app. It is more advanced than Photos but still free. To use it, open the Start menu and type “Video Editor.” Select the app. Click “New video project” and give it a name. Import your MP4 file by clicking “Add” then “From this PC.” Drag the video to the storyboard. Click the video clip on the storyboard, then select “Trim.” Use the sliders to set start and end points. Click “Done” and then “Finish video” to export. This method gives you more options like adding text or music.
Using VLC Media Player
VLC is a free media player that can also trim videos. First, download and install VLC from the official website. Open VLC and click “Media” then “Convert / Save.” Click “Add” to select your MP4 file. Click “Convert / Save” again. In the next window, check “Edit selected profile.” Under the “Encapsulation” tab, choose “MP4/MOV.” Go to the “Video codec” tab and check “Video” then “Keep original video track.” Under “Audio codec,” check “Audio” and “Keep original audio track.” Click “Save.” Now check “Edit options” and add a start time and stop time in the format “00:00:00” to “00:01:30” for example. Click “Save” then choose a destination file. This method works for any video format.
Using Online Trimming Tools
If you prefer not to install software, online tools work. Websites like Clideo, Kapwing, or Online Video Cutter let you upload an MP4, trim it, and download. Be careful with privacy. Do not upload sensitive videos. These tools are fast and require no setup. Just upload, trim, and download. Most are free with limits on file size.
Common Issues When Trimming MP4 Videos In Windows 10
Even with simple tools, problems can arise. Here are solutions to frequent issues.
Photos App Not Showing Trim Option
If the trim option is grayed out, your video might be in an unsupported format. Photos works best with MP4, MOV, and WMV. Convert your file to MP4 using a free converter like HandBrake. Also, make sure your Windows 10 is updated. Old versions may lack the trim feature.
Trimmed Video Quality Is Poor
The Photos app does not re-encode the video. It only cuts parts. So quality should remain the same. If you notice drops, check your original file. Also, when saving, choose a high-quality setting if prompted. Some online tools compress videos, so use desktop apps for best results.
Video Length Does Not Change After Trim
This happens if you did not save a copy correctly. Always click “Save a copy” not “Save” if you want to keep the original. Also, ensure you dragged the circles to the correct positions. Play the trimmed file to verify.
File Size Is Too Large After Trim
Trimming does not reduce file size much because the video is not re-encoded. To shrink the file, use a video compressor like HandBrake or the Video Editor app’s export settings. Choose a lower resolution or bitrate.
Tips For Better Trimming Results
Follow these tips to make your trimming smooth and professional.
- Always make a backup of your original video before trimming.
- Use keyboard shortcuts in the Photos app: Ctrl+Z to undo, Ctrl+S to save.
- Preview the entire trimmed section before saving to avoid mistakes.
- If you need precise cuts, zoom into the timeline in the Video Editor app.
- Name your trimmed files clearly, like “vacation_trimmed.mp4.”
- Close other programs while trimming to prevent lag.
- For long videos, trim in small sections and combine them later.
