About:
AtemOSC is a utility that exposes Blackmagic Design ATEM video switcher controls via the Open Sound Control (OSC) protocol. It acts as a bridge, allowing software like QLab, TouchOSC, and custom scripts to trigger switcher functions such as switching inputs, adjusting audio levels, and controlling downstream keyers. This enables seamless integration into show control systems for live events, broadcast, and theatrical productions.

Key Features:

Bidirectional OSC communication for both sending commands and receiving feedback
Comprehensive control over ATEM features including macros, audio mixing, and SuperSource
User-friendly interface for mapping OSC addresses to switcher functions
Support for multiple ATEM models via a single application

Use Cases:

Triggering video cues from QLab or other show control software in live theatre
Building custom touch panel interfaces for remote switcher operation
Automating switcher functions based on audio levels or other external data

Alternatives:

ATEM Television Studio – Hardware-based control panels; AtemOSC provides a software-based, highly customizable alternative.
Open Sound Control (OSC) Bridge for ATEM – Other OSC bridges may exist but AtemOSC is a well-established and feature-rich option.
