Is there a special license required for a rendering service like renderocket.com, or will the standard license work?
Yes, special licensing terms are required if you are creating a service that uses After Effects on the back end to process work submitted by other users. If you need to talk with someone about such license arrangements, I can put you in touch with one of our sales people.
That would be great if you can put me in touch with a sales person.
I've forwarded your email address and a link to this thread to the right folks.
