Trim Video with Photos on Windows 10

The Photos app in Windows 10 can shorten a video by setting new start and end points, then saving a trimmed copy. You’ll need the video file and enough free space for the exported version; the original normally remains unchanged.

What You’ll Need

• A Windows 10 PC with the video saved locally or available in a folder you can access.
• The built-in Photos app. If it is missing or will not open, install or update it through Microsoft Store, where available.
• Free storage space for the trimmed video. Exporting may take longer for large or high-resolution files.

Step-by-Step

1. Find the video. Open File Explorer and browse to the folder containing the clip. Photos can work with common formats such as MP4, but compatibility depends on the file’s video and audio codecs. If the clip is on a phone or camera, copy it to the PC first if it is not already accessible.
2. Open it in Photos. Right-click the video file, choose Open with, then select Photos. If Photos is not listed, select Choose another app and look for it in the list. You can also open Photos from the Start menu and browse to the file.
3. Open the trim controls. In the Photos video viewer, select the Trim button, usually shown as a trimming or editing icon near the top of the window. If you do not see it, check the app’s toolbar or the three-dot menu. The exact layout can differ between Photos versions.
4. Set the start point. The trim view shows a timeline with handles at its beginning and end. Drag the left handle to where the portion you want to keep begins. Use the play control to preview the clip, and move the playhead to check the moment precisely. The part before the left handle will be removed from the exported copy.
5. Set the end point. Drag the right handle to the last moment you want to keep. Preview the selection from near the beginning to the end; adjust either handle if the cut starts too late or ends too early. Keep the handles in the correct order so the selected section has a usable duration.
6. Save the trimmed clip. Select Save as rather than an option that replaces or modifies the original, if both choices appear. Choose a folder you can find again, enter a clear file name, and save. Photos creates a new file for the trimmed segment; the exact export choices depend on the app version and file.
7. Check the result. Open the saved copy in Photos or another video player. Confirm that it starts and ends where intended, and that picture and sound play correctly. If the result is wrong, reopen the original and repeat the trim rather than trimming the already shortened copy.

Common Mistakes

• Saving over the only copy: Choose Save as and use a different name or folder when possible. Keep the source until you have checked the export.
• Dragging the wrong handle: The left handle sets the start and the right handle sets the end. Preview the selected section before saving to catch a cut that removes the wrong part.
• Assuming the playhead is the trim point: Moving the playback cursor previews a moment; it does not necessarily change the selection. Adjust the timeline handles to define the portion to keep.
• Expecting frame-accurate editing: Photos is intended for basic trimming. If you need precise frame-by-frame cuts, multiple clips, transitions, or detailed audio edits, use a dedicated video editor.
• Closing the app before export finishes: Large files may take time to save. Wait for the operation to complete, then check that the output file exists and plays.

Tips

• Give the output a descriptive name, such as a subject and date, so it is easy to distinguish from the original.
• Use playback controls and the timeline together: pause near the desired cut, then adjust a handle and preview again.
• Trim a duplicate if the original is valuable or you are unsure about the cut. In File Explorer, copy and paste the source before editing.
• Keep the exported file in a folder with enough free space. A trimmed clip may still be large, depending on its resolution, encoding, and duration.
• If Photos offers multiple save choices, read them before selecting one. Choose the option that creates a separate file when you want to preserve the source.

Troubleshooting

Photos does not open the file: The file may use a format or codec Photos cannot decode. Try opening it with another player already installed on your PC, or obtain a compatible copy from the device that created it. Do not rename the file extension as a substitute for converting its format.

There is no Trim button: Confirm that you opened a video rather than a still image. Look along the toolbar and in the three-dot menu, and check for Photos updates through Microsoft Store. If your Photos version has a different interface or lacks the trim feature, use a video editor that supports trimming.

The app freezes or export fails: Wait briefly, especially with a large clip, then check free disk space and try saving to a local folder such as Videos. Close other demanding apps and reopen Photos. If the problem continues, restart Windows and try again. Preserve the original file while diagnosing the issue.

The saved video has unexpected cuts: Reopen the original and verify both handles before saving again. Make sure you are watching the new output, not the source or an older export with a similar name.

The picture works but sound is missing: Check whether the source itself has audio and whether it plays in Photos before trimming. If sound is present in the source but absent in the export, try another compatible player or editor; Photos may not handle every codec combination identically.

Frequently Asked Questions

Does trimming in Photos delete the original?
Choose Save as to create a separate trimmed file. Keep the original until you have checked the saved copy.

Can I trim the middle out of a video?
The basic Trim tool selects one continuous segment, usually by setting its start and end. Removing a section from the middle and joining the parts requires an editor with splitting or multi-clip tools.

Can I trim a video without installing an app?
Photos is built into many Windows 10 installations. If it is absent, unavailable, or unable to open the file, you will need another compatible editor or player.

Will trimming reduce the video file size?
It can, because the saved clip is shorter, but the amount depends on the export settings and encoding. Photos may re-encode the video, so the result’s size and quality can differ from what you expect.

Why does my video look different after saving?
Exporting may change how the video is encoded, and some source formats are not fully supported. Compare the output with the original and try a different compatible editor if quality, color, or playback is unacceptable.

Can I undo a trim later?
If you saved a separate copy, the original is still available and you can make another trim from it. If you replaced or deleted the source, recovery depends on whether you have a backup or a recoverable copy.
