Requires Chrome or Edge; WebUSB is not available in Safari or Firefox. Nothing is installed and nothing leaves your machine — the page talks to the reader directly.
Click the status in the top right for the session log — dropouts, timecode jumps, frame rate changes. It records its own blind spots too, so a gap means this page was not watching rather than that nothing happened.
Protocol notes, a Python reader and the source for this page: github.com/hugesesame/adrienne-usbtc. Diagnostics if the device will not connect.
