Remove the silences and "ums" from your video without cutting a single word
Silences, "ums", sentences restarted three times: that's what makes viewers drop off, and it's the most tedious part of editing. With ManyMotion, you upload your video and the AI removes the silences based on a word-by-word transcript. Dead air, filler words, false starts and repeats disappear, and cuts always land between two words. You get a shorter, tighter video without listening to your take ten times.

Why ManyMotion
Never in the middle of a word
Cuts rely on the exact timestamp of each word: no clipped syllables, no choppy audio.
More than silences
Hesitations, "ums", false starts, repeated sentences: the AI keeps your best take and removes the rest.
Clean jump cuts
Cuts can be hidden with a slight zoom, so your face doesn't jump from one frame to the next.
The pacing you want
Super tight TikTok-style, or more natural for a training video: say it in one sentence.
The rest of the edit as a bonus
Captions, music, sound effects and zooms can be added in the same request.
How it works
01
Upload your video
MP4, MOV or WebM, up to 30 minutes, even shot on a phone.
02
The AI cuts the dead air
Silences, "ums", false starts and repeats are removed, between two words.
03
Tweak and export
Too tight? Not tight enough? Say so in the chat, then download your MP4.
Why dead air kills a video
Talking face to face, a pause is natural. In a video, on a feed where the next one is a thumb swipe away, every silence is an invitation to leave. Half a second of dead air repeated twenty times is ten seconds of nothing in your video.
Creators who hold their audience cut almost every breath. It's not a fad: it's an information density that leaves no time to get bored. Our guide on how to remove silences from a video covers the method and the cases where a pause is worth keeping.
What the AI removes, and how
| What gets removed | Example | How the AI spots it |
|---|---|---|
| Silences | A second of dead air between two sentences | No words in the transcript |
| Filler words | "um", "uh", "like" | Filler words detected in the transcript |
| False starts | "So today... no, wait. Today we're going to look at..." | A sentence cut off, then restarted |
| Repeats | The same sentence said three times | Very similar passages: the best take is kept |
It all relies on the word-by-word transcript with exact timestamps. A simple volume detector cuts as soon as the sound drops, at the risk of clipping the end of a softly spoken word. A word-guided cut lands in the gap between two words, where the ear doesn't notice a thing.
Hiding the cuts: jump cuts, zooms and B-roll
When you cut a passage from a talking-head video, your head "jumps" slightly from one frame to the next. That's a jump cut. On TikTok, it's part of the style. On a calmer video, you may want to soften it. Three techniques:
- The punch-in zoom: the next shot is slightly tighter. The cut becomes a deliberate change of shot.
- B-roll: while your voice keeps going, viewers see your product, your screen or your location. Upload these clips with your main video.
- The transition: a flash, a blur or a whip to mark a new section, best kept for real changes of topic.
Preparing your take for easy cuts
- Take a real pause when you slip up, then restart the sentence from the beginning. The AI spots a clean retake much better than a word corrected on the fly.
- Avoid background music while filming: it ends up chopped into pieces at every cut. ManyMotion adds continuous music during the edit anyway.
- Speak at a normal pace: no need to rush, the silences will be removed afterwards.
- Keep your framing fixed: a phone on a stand, not handheld. The cuts are much less noticeable.
Once the silences are gone, add auto captions and visual rhythm: that's what talking-head video editing is all about.
Frequently asked questions
How do I remove silences from a video automatically?
+
Upload your video to ManyMotion and ask it to cut the silences. The AI transcribes every word with its exact timestamp, then removes silences, filler words, false starts and repeats, always cutting between two words.
Can the AI cut an important word by mistake?
+
Cuts land between words, never in the middle of one. If a passage you wanted to keep was removed, just ask: "put back the sentence about delivery times".
Can I keep a natural pace?
+
Yes. Say "natural pace, keep a few breaths" for a training video or an interview, or "very tight" for TikTok.
How much shorter will my video get?
+
It depends on how you speak. An improvised take often gets noticeably shorter, a take read from a teleprompter much less so. You only pay for the final length: 1 credit per 2 seconds, plus 2 credits per minute of upload.
