Hello!
I've been shooting stock video for a few years on my own. Now I'd like to hire a videographer to help me and shoot video for me.
What type of contract should I make between me and this videographer so that I own the copyright on the video he makes, and so that I can sell it on any stock agency website?
Currently I'm producing stock video as a freelancer, so I don't have a company yet. Is it possible to make this contract between me and him as freelancers, or I must start a company and make the contract between my company and him? Does this contract need to be registered somewhere (I want it to be valid worldwide)? Do I need to send this contract/inform the stock agency about this? Note that these are related only to the copyright for video aspect of the contract.
Yes, I know I have a lot of questions

, but if any of you have any experience in these I'd relay appreciate your insight, or examples of such contracts.
Thank you!
