Pause Cutter — 去停頓剪輯

Drop in a talking video — a vlog, lecture, tutorial, podcast video or livestream clip — and get it back with the silent pauses cut out. A finished MP4, not just an edit list.

It runs on your own computer with ffmpeg. Nothing is uploaded and no API key is needed.

What you get

• your-video-cut.mp4: the same video, tighter. Resolution is kept and the picture and sound stay in sync.
• cuts.csv: every cut, where it lands in the result, and how many seconds were removed

Three strengths

• Light: only pauses of 1 second or more. Keeps a natural rhythm.
• Normal (default): pauses of 0.6 seconds or more
• Strong: pauses of 0.35 seconds or more, for a fast jump-cut style

Each cut keeps a little air before and after so words are not clipped. The levels adapt to your own recording's background and voice.

Fix it by chatting

• "Keep the pause at 1:23"
• "Put cut 4 back"
• "Also cut 2:10 to 2:14, I fumbled there"
• "Make it lighter"

Only the changed parts are rendered again, so fixes come back quickly.

Tested on a real recording

A 10-minute unedited livestream clip (1080p): 10:00 → 6:57 on Normal (134 cuts), 6:27 on Strong. Each took about 2½ minutes on an ordinary laptop.

Limits

• Pauses are found by loudness. Silence filled with background music is kept, and a very soft word can be cut short. Watch the result and ask for fixes.
• It does not remove filler words such as "um" or "uh"
• It does not add captions, reframe or add music
• Up to 60 minutes and 4 GB per video
• Needs Python 3.9+ and ffmpeg. The agent installs ffmpeg after asking you.
• Your original video is never changed
