About royalty fee of 360 degree movie and video usage of Content Example

Hi.
I would like to use Unreal Engine 4 for commercial use with 360 degree video production.

Do I need to pay royalties for non-interactive 360 degree videos created with Unreal Engine?

Also, do I need to pay royalties for commercial videos that I make on Unreal Engine 4 using StarterContents and some of the assets in Content Example?

Thank you for your time.

Non-interactive 360 degree videos are royalty-free. This is still the case if the video contains free content provided by Epic.
