To my knowledge, there is no "industry standard" contract or license for use of intellectual property.
Too many variables now exist, such as California vs. the rest of the world - every artist has to sign off on a piece before you can use it...the rights of celebrity to control the use of their likeness and voice, regardless if their orignal work was a work for hire or not...no central clearinghouse for rights issuance.
We give this advice almost every time...if you are new to the industry and you are promoting/producing/selling a work that has copyrighted material in it, please contact an attorney that specializes in entertainment law. The up front cost of the consult is far less expensive than the lawsuit that inevitably follows.
As always...good luck - this is an issue that is stopping many independent voices from being heard.
Having evolved from an engineering firm in the highly-litigious construction industry, our company started with a basic contract (you pay me $x for me to do task y by such & such a time, etc.). Then, we simply added to it. Our attorney (for the engineering firm) once told me that there is no such thing as the perfect contract... we just contemplate possible problems and write clauses to try to eliminate their impact.
Concern that clients may try to re-use programs beyond their intended use caused me to add the clause which states that Client will be liable for 3x the original contract fees for uses beyond the scope of the agreement unless otherwise agreed-to in writing. That catches their attention! WHEN they fuss about it, I simply state that if they don't intend to breech the contract, they've nothing to be concerned about. If they wish to expand the application of the program, though, you must be willing to be reasonable on your re-use rates. This can often wind up being an ownership discussion as well.
I would love to know how many corporate video producers/companies retain ownership of the final program versus relinquishing all rights to their clients.
Hopefully, this will shed a little light on the issue.
