What I learned about Copyright

That if you don't copyright your own original work people can copyright it. If you take other peoples work with out giving them credit you can get sued. If you take some one's work and change it so that it isn't the same thing you have to make sure that it is completely different and that you are using less than 10% of their original works. I don't really know much about the positions in video production. i know there is the person paying for it the product its self and the person buying it. Other than that i really don't know much.
