Communication your vision is about being clear, articulate about it, but not being dogmatic. That’s tricky because if you’re the director or writer or the primary creative in whatever process, you have to give a sense of direction.
The editor usually never meets the crew. Like everything else, if you can bring everyone together at the start, everything is protocol. If there’s a conflict that erupts, take a break and don’t humiliate them publicly.
Documentary is about trying to find the truth. You have to be honest with them. Usually, people make the mistake of tricking the subjects and not telling them everything – which backfires.
Ask people open-ended questions because people often say what’s on their mind. Don’t use a list of questions, but a list of bullet points or words or themes that you want to deal with.
