Hi, I'm selling pregnancy products. In order to give more knowledge to my customers and make them happy, I have a plan to download some pregnancy videos from Youtube, edit them to add 'courtesy of Youtube' text on each videos, and then burn them on DVD. That DVD will be given as bonus for my customers. Is it allowed? Thanks in advance.
If you are selling them, you will need to contact the maker and get express permission to use them. And, potentially offer them a percentage of the proceeds. Courtesy of only works in education or non-profit materials. Be careful. This could be more costly on the other end, if you don't cover all the bases. Good luck in the much-needed information getting to the public!
