Pre-production: How much does the attorney want to be involved?

Fortunately, most attorneys are sophisticated media consumers. Despite the nineteenth century having served the law well for hundreds of years, they know that making video involves more than owning a camcorder.
Often, the earliest questions I ask are, "Have you made media before?" and "How did it go, did you get what you needed for the case?"

One assessment I always make is, "How much attention, patience, cognitive overhead, does this attorney have for creating media for this case?" I'm a producer because I dig almost every aspect of the art and craft. (If I could have someone else wind up the cords and worry about the batteries, it would be perfect.) But the attorney has other stuff to worry about, I guess.

If it's your case, do you want to script it or have me do a rough draft and then consult you?
Do you want to be at the shoots?
Do you like to sit in the edit bay with me or would you rather I just bring you a rough edit and talk about it?
Fortunately for me, motion pictures+sound is potentially one of the most complex artforms, up there with architecture and grand opera. So specialists like me will get paid for keeping all that stuff in my head. But attorney collaboration is crucial.
Finding the right balance of hands-on versus call me when it's done, that's the first task.

TIP: Audio is the secret weapon

Which medium survived, silent movies or radio?
When you're making video, give at least half your attention to the sound, to what the jury will hear.
Two facts about audio:
1) Audio is irresistible. People don't have their defenses up for what they hear. It can even effect an audience unnoticed.
2) Good audio is essential. You can have pictures recorded by your phone, xeroxed through several generations, and they can still work if the audio is good. But not vice versa. Modern audiences don't forgive bad audio.

Static, wavering volume levels, 60 cycle hums, rustling papers--listeners will tune you out.
Intelligible speech, with warm close miking, powerful sound effects, (even music if it's settlement video)--sound can save a presentation.

I have several mics each of which cost more than my car and they're worth their weight in jury awards!
