I have doubts whether the live stream was really live.

During the live-stream the subtitles are shown line by line.

When subtitles are auto-generated, they pop up word by word, which I assume would need to happen during a real live stream.

Line-by-line subtitles are shown if the uploader provides captions by themselves for an existing video, the only way OpenAI could provide captions ahead of time, is if the "live-stream" isn't actually live.
