How to use Cut out parts
- Choose your video.
- Add the start and end time for each part to remove.
- Download the final MP4 without those parts.
What this tool does
Cut out parts removes one or more unwanted time ranges and keeps the rest of the video. Use it for pauses, delays, private details, mistakes, or short sections that should not appear in the final export.
Unlike trimming, this does not keep only one continuous range. It keeps the sections before and after each removed part, then merges those kept sections into one MP4.
How browser processing works
The selected video is processed locally with FFmpeg WebAssembly. The tool creates temporary kept segments inside the browser, joins them, and then offers the merged MP4 as a download.
Supported formats and output
- Input
- Browser-readable video files such as MP4, MOV, WebM, and other formats supported by the browser FFmpeg engine.
- Output
- MP4 containing the original video minus the removed time ranges.
Practical examples
Remove a delay
Cut out 5:36 to 5:49 to remove a pause while keeping the video before 5:36 and after 5:49.
Remove private details
Cut out a short section that shows unwanted information, then export the remaining video as one MP4.
Quality considerations
- Use precise start and end times such as 5:36 and 5:49 for minute-second inputs.
- Because the kept parts are merged, the final video duration should be the original duration minus the removed ranges.
Limitations
- Cuts are re-encoded for compatibility, so processing can take longer than a simple trim.
- Removing many ranges from a large file can use significant browser memory.
- If the source contains unusual audio or video codecs, export may fail in some browsers.
Frequently asked questions
Is this different from trimming?
Yes. Trimming keeps one selected range. Cut out parts removes selected ranges and keeps everything else.
Can I remove more than one part?
Yes. Add multiple ranges such as 0:15 to 0:20 and 1:05 to 1:09.
Is my file uploaded?
No. The removal and merge steps run locally in your browser using WebAssembly.
Troubleshooting
I removed 5 seconds, but the final duration is not exact.
Video timestamps and frame boundaries can vary slightly. Try adjusting the start or end time by a fraction of a second if the cut lands early or late.
The export fails after several ranges.
Try fewer ranges first, close other heavy tabs, or split the source into smaller parts before cutting.
