I don't understand some parts of this, the writing doesn't seem to flow logically from one thought to another.

    >  Second, we are going to have to somehow make money for video generation. People are generating much more than we expected per user, and a lot of videos are being generated for very small audiences. 
    > We are going to try sharing some of this revenue with rightsholders who want their characters generated by users. 
    > The exact model will take some trial and error to figure out, but we plan to start very soon. Our hope is that the new kind of engagement is even more valuable than the revenue share, but of course we we want both to be valuable.

The first part of this paragraph implies that the video generation service is more expensive than they expected, because users are generating more videos than they expected and sharing them less. The next sentence then references sharing revenue with "rightsholders"? What revenue? The first part makes it sound like there's very little left over after paying for inference.

Secondly, to make a prediction about the future business model - it sounds like large companies (disney, nintendo, etc) will be able to enter revenue sharing agreements with OpenAI where users pay extra to use specific brand characters in their generated videos, and some of that licensing cost will be returned to the "rightsholders". But I bet everyone else - you, me, small youtube celebrities - will be left out in the cold with no controls over their likeness. After all, it's not like they could possibly identify every single living person and tie them to their likeness.
