You already do the hard part
You know your subject. The telling lets it down.
Take one expert who films. Say he is a doctor with a clinic and a phone full of videos. Call him Dr Rao.
What you already do well
Dr Rao knows things it took twenty years to learn. People trust him the moment he speaks.
What happens after filming
He films three videos on a Sunday. They sit in his phone for three weeks. One goes out, late, with no caption.
What he never sees
The two videos that never went out reached nobody. He has no record of the people they would have brought. So it never feels like a loss.
