My first exposure to a multi-camera live broadcast event was in an earlier career when the local TV station set up for a broadcast in the theater I worked for. There were two trucks in the alley way. Cables running everywhere, and two days to set up. Running it all was a team of 12 people.
Yesterday, we did a three camera live broadcast and I carried the broadcast gear in my shoulder bag and was set up in an hour.
That’s a pretty serious change!
