Cuts silence from ONE video with auto-editor and normalizes the audio to -14 LUFS. With the `--fillers` flag, also removes filler words, stutters and duplicate takes (the speaker restarting a segment after an error), using word-level transcription plus agent judgment. Triggers "cut the silences", "remove the pauses from this video", "trim the dead air", "speed this video up by cutting pauses", "corta os silêncios", "tira as pausas do vídeo", "tira os tempos mortos", "tira os né/tá do vídeo…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
## What this skill does
Automatically cuts pauses and silence from talking-head videos using `auto-editor`, then normalizes the audio loudness with `ffmpeg-normalize`.
- **Cost:** $0 in default mode — the tools are free, open source and fully offline
- **Quality:** keeps the original video quality (no video re-encode during normalization, `-c:v copy`)
- **Audio:** linear gain to -14 LUFS plus a peak limiter. The voice's dynamics are never compressed; the limiter only shaves transients (mouse clicks, keyboard) that would otherwise cap the gain. The delivered loudness is always **measured**, never assumed
- **Output:** writes the edited video to `<OUTPUT>/` (see convention below), never overwrites the original
**Optional `--fillers` mode:** also removes filler words ("né", "tá", parasitic "tipo"), stutters, and duplicate takes — where the speaker errs, stops, and redoes a segment from the top. Costs a few cents of API (OpenRouter) because it has to transcribe. **Never runs unless the user asks.** See "Step 5b".

How to install
mdr add andersonadelino/skills/cut-silence@sha256:5be03535c2098b28The line at the top of this page pins the label git:20260916.d4dc687, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
