Settlement video: Yes, write a script; save money; save your case.

I have $750 for every time an attorney has insisted I go out and shoot first, and then we'll see what we get and edit that.
That extra money is a rough guess for the average extra cost for not planning.
Sample later conversations:
"You didn't get closeups of her legally blind eyes? You need to go back to Peoria and shoot that."
"We need to have him say something about his kids. When can you re-shoot?"
"The family cleaned out the house two months after he died and threw out the photos and the video. Can you go back and shoot the house? It's all we've got."

Please, for the love of winning, plan. Plan right away. Plan before the relatives move away, before the hard drive gets erased, before the plaintiff's condition changes, before the site gets repaired and new guard rails are installed, before the cost of making your case goes up.

Media Case Plan, your next good idea.
