Autocut — Install

What's in this package

• autocut.py — launcher + state machine + HTTP/SSE server
• dashboard.html — browser UI (served at http://localhost)
• atem-levels.js — Node helper that talks to the ATEM
• install.sh — one-shot build script (produces Autocut.app)
• package.sh — bundles .app + Node binary into a distributable zip
• favicon.png — the AC by @djchemic icon

First install

Drop all files into one folder, e.g. ~/Downloads/Files, then:

cd ~/Downloads/Files
bash install.sh

The script installs python@3.12, node, pyinstaller, zeroconf, and atem-connection (via npm), then builds Autocut.app and opens it. First run takes 1-2 minutes; subsequent rebuilds are faster.

Rebuild after changes

Same command. The script wipes the iconset and Launch Services cache so icon and dashboard changes always take effect:

bash install.sh

If the Mac app icon doesn't refresh in Finder, the script flushes lsregister and restarts Dock + Finder automatically — you'll see them flash for a moment.

Distribute to another Mac (Apple Silicon)

After install.sh builds the app:

bash package.sh

Produces Autocut-Mac-AppleSilicon.zip (~80 MB). Recipient unzips, drags Autocut.app to /Applications, right-clicks → Open the first time to bypass Gatekeeper. Or strip the quarantine attribute:

xattr -dr com.apple.quarantine /Applications/Autocut.app

Config & recovery

Settings live at:

~/Library/Application Support/Autocut/config.json

A .bak is written on every save. If a rebuild ever scrambles your config:

cd ~/Library/Application\ Support/Autocut
cp config.json.bak config.json

Routing to Atem Mini Pro Iso/or other models

• use the Mic1 and Mic2 input at the back
• For Mic1 i choosed host and for Mic2 guest(s)
• I have routed from RodeCaster Pro II 3.5mm jacks via "Custom mix"
• Rodecaster Pro II lets you select which channel goes where by "Routing"
• Dont forget to set Atem Mini inputs to Line not to microphone input.

Default working values

• Mic 1 input: 1301, gate -37 dB, attack 500 ms, release 450 ms
• Mic 2 input: 1302, gate -37.5 dB, attack 400 ms, release 450 ms
• Both Gate: -41 dB, Both Release: 1900 ms
• Both Overlap: 2800 ms, Min Hold: 600 ms
• Cam mapping: BOTH=1, SOLO_1=2, SOLO_2=3

Recovery to v1.1.1 baseline

If a later change breaks something, autocut-v1.1.1-source.zip (shipped separately) is the saved working snapshot — unzip over your files and rebuild.
