I’ve been obsessed with how Japanese TV shows composite animated lower thirds over live footage—those layered graphics that somehow feel both playful and precise.
To learn the craft, I built KeyCast Lower Thirds, an Electron + React app that mimics broadcast workflows without the usual control-room headaches. You get a clean operator panel, a fullscreen kiosk output, and real-time sync between the two. Toggle text, colors, placements, and animated logos instantly, then ship the feed straight into OBS or an ATEM via chroma key or alpha workflows.
In practice, it’s become my sandbox for experimenting with conference graphics, live presentations, and camera overlays. Start the kiosk, pick your key color, drop in a looping logo, and you’re producing show-ready lower thirds in minutes. The repo includes presets, display management, and an extensible architecture if you want to push deeper into automation or alpha-channel pipelines.
