You can use UE4 under the standard EULA for film production. You do not owe royalty for revenues received for non-interactive linear media (e.g., tv shows). Please check out Section 5 of the EULA (EULA - Unreal Engine).
Unreal Studio provides you with some extra tools, including Datasmith. You can find more information in our FAQ (Frequently Asked Questions - Unreal Engine) to see if it better suits your needs. Please note that Studio is currently in open beta and will require a paid license at the end of the beta.
