I disagree with Arnie. The one thing I’ve learned in twenty-nime years of business as an independent is that lawyers don’t have all the answers, but they do want all your money.
All you have to do in this case is obtain a license agreement from one of the companies already doing business in that arena, and just tailor their license to your needs. A lawyer would do exactly the same thing. The most important words in a stock footage agreement, and the words you absolutely have to put in for self-protection, are “for use in _______________ (program title) for one time use, only.” In theory, this prevents the licensee, from incorporating the lisensor’s footage into additional programs. It will happen anyway from time to time, and you must be on the lookout for your stuff and remain vigilant. For the most part, like anyone in sales, your job is to fulfill a need, and get their money in your coffers before they go to the next seller. What happens after the sale is a bit out of your control no matter how ironclad your license may be.
