When video cameras are set up, you have to white balance
the cameras. that so can make sure the stage lighting is correct.
Also if you notice during the wait time for Trump’s speech,
people would go to the podium for a second and then leave.
That’s the news networks checking their cameras.
That’s part of my naval training. I know a little in video production. Helped in training tapes and family grams.
