We will be doing a content sharing deal with a major manufacturer. They need the content to support their products, we want the content for monetization on our YouTube channel. The manufacturer plans to build a library of content and put it on their site so customers can access it when looking at their products, but we feel people will find it on our page using search therefore its a win-win. Also, since its cobranded, we are both OK if viewers see it on each other's pages.

I know that YouTube will only allow one channel to monetize the same content. My question is this: Since my channel would want to spread out the content, publishing some each week, yet the manufacturer wants it all on their site at one time, would YouTube consider us to be the first publisher of the content if we were to post it to our page, while leaving it private or scheduled for a later date before the manufacturer posts it, or do they decide who gets paid based upon first public access to the material?
