4U2CUVC Webcam Controller

Starting my Github page with a delighfully overengineered utility I made for myself to dial in the exposure on my Razer Kiyo Pro Ultra webcam. Razer has software that does some of this, but not the way I wanted, plus as a video and photo nerd I had thoughts about scopes and extra goodies. Experimenting with both Claude Code and Codex, I figured out what controls the camera exposed via UVC and built a simple web interface to dial in things like ISO, shutter speed, and a number of other settings. Then came a waveform, vectorscope, false color, and a skin keyer to further dial in exposure and skin tones.

Makes me want to rethink camera hardware interaction again. It still seems like no one has ever figured it out fully.

Updated with a new design system in September, 2026, but the original is still on GitHub here.
