D & K Audio and Tech Solutions showcases a custom technology setup built for a church to simplify live production by controlling multiple PTZ cameras and an ATEM Mini switcher through Bitfocus Companion with an Elgato Virtual Stream Deck. Using a four-camera layout (center, left, right, and back), the workflow enables selecting a camera, loading presets, placing it into preview, and triggering a transition to live, along with full PTZ functions like pan, tilt, and zoom—without a joystick or keyboard. The video also demonstrates how to use Companion without a physical Stream Deck by embedding the Companion button emulator into OBS as a custom browser dock, configuring buttons for preview and auto transition, adjusting labels and feedback text color, fixing column display, and organizing OBS docks to manage workspace.
