Generally around an hour: the amount of time I spend on-site, and the amount of time I need the client present are two different things, and I work hard to minimise disruption to their day.
It normally takes around 45 minutes for me to set up the filming equipment, during this time the client can be doing their own work. The interview itself takes around half an hour, and then it’s good to have some time to film action ‘b-roll’ which helps to illustrate the story.
