The Kata Architecture Committee recordings start with one hour of black screen

[c3d]

I wanted to check something from the recording we make of the architecture committee meetings, and accessed the last recording as linked from the meeting nodes.

The recording starts with about one hour of black screen with just @liubin's name in the middle. I suspect the recording is scheduled, and the scheduling time is wrong. Maybe scheduling on time is sufficient, since we usually begin the meeting with a bit of chit chat, and it's not that harmful if we miss a little of that. Or start the meeting manually?
