How to Remove a Mistake From the Middle of a Video
Open Remove Part of Video, put the two handles around the mistake, press Remove this part, then play it back: the preview skips the marked part. Press Remove parts to export. Turn on Exact cut (slower) if the join must land on the exact frame.
What this fix does
A trim keeps one range and throws away the ends. Removing a mistake is the opposite: you mark the part you do not want, and everything before and after it is joined back together into one video.
ClipCut's Remove Part of Video tool does this in your browser. The file stays on your device and nothing is uploaded. You can remove one part or several in a single export.
Step by step in ClipCut
1. Open Remove Part of Video and drop in your video. A small slice near the middle is selected to start with.
2. Find the mistake. Play the video and press ⇤ Start here just before the mistake begins, then End here ⇥ just after it ends. You can also drag the two handles on the timeline.
3. Fine tune the edges. Tap the Start or End time to choose which point moves, then use the nudge buttons (−1 s, −0.1, +0.1, +1 s). The Length readout shows how long the marked part is.
4. Press ✂ Remove this part. The part turns red on the timeline and appears in a list under it, with a summary of how much is removed and the new length.
5. Repeat for any other mistakes. Overlapping parts are merged into one. To bring a part back, press the ✕ next to it in the list (its label is Keep this part).
6. Press Remove parts. The result card shows the file size on the Download button, plus Before and After to compare and Keep editing if you want to change something.
Check the join before you export
Before exporting, press ▶ Play from a few seconds before the mistake. While the video plays, ClipCut jumps over every part marked in red, so you hear the edit the way it will flow in the final file.
Listen for three things at the join: a word cut in half, a repeated word or breath, and a jump in the picture that looks odd. If a word is clipped, move the edge back with −0.1. If a bit of the mistake is still there, move it forward with +0.1. Keep cuts in natural pauses where you can, since a join in silence is far less noticeable than one in the middle of a sentence.
These are suggestions, not rules. A visible jump is normal when the camera or the person moved during the removed part.
Fast mode or Exact cut
With Exact cut (slower) off, ClipCut copies the original video and sound without re-encoding, so there is no quality loss and the file keeps its format. The catch is that a kept part can only restart on a keyframe, a full picture stored every so often in the file. Each part after a cut therefore starts at the keyframe before your chosen end point, so a little of the removed part can stay in. Depending on the file, that can be up to a few seconds.
If the keyframes are so far apart that more than about a second of what you marked would stay in, ClipCut switches to an exact cut on its own rather than hand back a nearly unchanged video, as long as it can decode the video. If it cannot, the result says how much was removed and that fast mode could not remove all of it, and suggests turning on Exact cut.
With Exact cut on, every cut lands on the exact frame you picked. ClipCut re-encodes the video to an MP4 with H.264 video and AAC sound, which takes longer and costs a little detail, usually hard to see.
How to check the final file
Compare the length. The summary under the timeline gives the new length; the downloaded video should be about that long. In fast mode it can be slightly longer, because of the keyframe rule above.
Play the whole result once, paying attention to each join and to whether the sound stays in sync with the picture after it. ClipCut also checks every export before offering it and says so if the result comes out empty, too short or will not play in your browser.
If something is wrong, press Keep editing. Your marked parts are still there, so you can move an edge or turn on Exact cut and export again.
Limits
Fast mode cannot place a join on an exact frame. Use Exact cut when that matters.
Exact cut always gives an MP4, and it scales very large videos down so that neither side is wider than 1920 pixels. A 4K recording comes out at about 1080p. If you need to keep 4K, use fast mode and accept a less precise join.
You cannot remove the whole video; ClipCut asks you to pick a smaller part. A removed part is gone from both the picture and the sound, so this tool cannot cut only the audio or only the picture.
If you see a message that the video could not be read for a fast cut, turn on Exact cut and try again. Some videos use the AV1 codec, which ClipCut cannot decode yet, so Exact cut will not work for them.
Long or high resolution files take longer, especially with Exact cut, and can run out of browser memory on phones. A laptop or desktop in a modern browser handles them more comfortably, and closing other tabs helps.
Only edit footage you own or have permission to use.
When another tool fits better
If the mistake is at the very start or end, the Video Trimmer is simpler: set the start and end you want to keep. If you want to remove many short pauses from a talking video, the Silence Remover finds them for you instead of marking each one by hand.
