A video production helper for use with mainly ATEM Mini switchers for keying information to the video feed and/or the talent. The information can be used for upstream keying as a chroma keying background or downstream keying as an overlay.
Fully open source, GPLv3, built on Qt/QtQuick (5.15) so runs on pretty much anything, Linux (Desktop, Raspberry Pi, etc), Windows and macOS.
Network is not required in any way, no cloud or anything like that. Runs fully on your own system.
