autocut

Remove silent gaps from videos in seconds. Drop a video, tweak a couple of sliders, export an MP4 or send the timeline to DaVinci Resolve / Premiere.

What it does

• Finds the spoken parts of your video automatically
• Lets you preview the cut version before exporting
• Lets you fine-tune individual cuts (drag the edges on the timeline, or edit in/out timestamps in the cuts panel)
• Exports a ready-to-share MP4 with the silence removed
• Or exports an FCPXML that DaVinci Resolve and Adobe Premiere import as a clean timeline, source timecode preserved

No accounts, no uploads, no Python, no ffmpeg install. Everything runs on your machine.

Install

macOS Apple Silicon — Homebrew (recommended)

brew install --cask cobanov/tap/autocut

Brew handles the macOS Gatekeeper quarantine flag for you, so the app just launches. To upgrade later: brew upgrade --cask autocut.

macOS Apple Silicon — manual

1. Download the latest .dmg

2. Open the .dmg, drag autocut into Applications, eject the dmg

3. Open Terminal and run this once:

   xattr -cr /Applications/autocut.app
   

4. Launch the app from Applications

The bundle isn't notarized by Apple yet, so macOS Gatekeeper flags it as "damaged" until you strip the quarantine flag with that command. Brew does this step for you automatically — that's why it's the easier path.

Windows x86_64

1. Download the latest installer — autocut_X.Y.Z_x64-setup.exe (NSIS) or autocut_X.Y.Z_x64_en-US.msi (MSI)
2. Run the installer. SmartScreen warns on first launch because the bundle is unsigned — click More info → Run anyway.
3. Launch autocut from the Start menu

Linux

Build from source for now (see the source tree). Native builds are on the way.

How to use

1. Drop a video onto the window (or click browse files). MP4, MOV, MKV, WebM and AVI all work.
2. Click detect silences in the panel on the left. autocut analyzes the audio and marks the spoken regions green, the silent regions red.
3. Watch the preview. Hit space to play / pause. The player skips the removed parts automatically so you hear the final cut as you go.
4. Refine if you want:
   • Drag the green edge handles on the timeline to nudge a cut
   • Edit the exact in / out times in the cuts panel on the right
   • Click the × on a row to disable that keep (it turns purple, gets excluded from the export, but you can bring it back with one click)
   • Adjust the sliders (threshold, pad, min silence, min speech) to change how aggressive the detection is. Hold shift for fine steps.
5. Export:
   • MP4 for a finished video file you can share immediately
   • FCPXML to import into DaVinci or Premiere with the exact cuts already on the timeline

That's it.

Tips

• Got a long video? Turn on preview range only in the parameters panel so detection runs on a short slice while you tune the sliders. The full video gets processed when you hit export.
• DaVinci Resolve users: the FCPXML keeps your source timecode, so the clip auto-links to the original media file without a "media offline" dialog.
• Scroll on the timeline pans it left/right. Drag the small window in the navigator below to zoom into a specific section.
