Bright Aside Publisher

Bright Aside Publisher is a private tool that produces and schedules short British history videos for a YouTube channel selected by its operator.

The operator’s Mac produces reviewed video files and places them in a private Google Drive folder. An Apps Script publisher reads that folder, uploads videos privately to the selected channel, and verifies their scheduled release through YouTube. The configured release window is 9 am to 6 pm UK time, on the hour.

This site describes the tool for its Google authorization screen. Only the operator uses the publisher.
