How to remove pauses and ums from a video without editing software

01

How Cut Studio finds the pauses

Cut Studio measures the loudness of your recording every 20 milliseconds and learns how quiet your room is. Only silence longer than your threshold is cut, and a short breath stays on both sides, so the speech keeps its rhythm instead of sounding chopped. Silence before the first and after the last word goes completely.

Because it listens to the sound level rather than to words, finding pauses needs no AI download and works in any language. On our test computer, the pauses of a ten-minute video were marked in about a second.

Cut the pauses in four steps

1. Open your file

   Select “Choose a file” and pick a video or a sound file, for example a phone recording or a podcast episode. It stays on your device.

2. Set the threshold

   Under “Shorten pauses”, “Pauses longer than” starts at 0.7 seconds and “Breath that stays” at 0.2 seconds. Raise the threshold for a calmer style; lower it for fast social media clips.

3. Check the preview

   Every cut pause appears crossed out in the text and on the timeline. Play the preview: it jumps over the cuts exactly as the finished file will. Click a pause to keep it after all.

4. Export

   Select “Export”, keep “Video (MP4)” – or “Sound only (M4A)” for a podcast – and choose “Export now”. The shorter file is saved on your device.

03

Remove ums and repeated words

Pauses are only half of it. Turn on “Recognize the words too”: a speech model then writes down every word, and Cut Studio can mark hesitations with “Remove ums and stray sounds” and phrases like “I I think” with “Remove doubled words”. The model downloads once and then runs in your browser.

With a graphics chip, the words of a ten-minute video were ready in about one and a half minutes on our test computer. Phones work too; there, clips of up to about 15 to 20 minutes are the safe choice.

04

Edit the video like a document

Once the words are there, the transcript becomes your editor. Click a word to jump to it; drag across several words to cut a whole sentence; press Ctrl+Z to undo. Every cut gets a key frame and a short fade, so there are no jumps in the picture and no clicks in the sound.

Your edits are kept in this browser. If you close the tab by mistake, open the same file again and continue where you stopped.

• Delete a false start instead of recording the sentence again.
• Keep a deliberate pause before a punchline by clicking it.
• Export subtitles timed to the edited video as SRT or VTT.

05

Choose the right file

A cut list keeps your edit without encoding a new video: your editing program applies the same cuts to the original file.
