Once your subscription expires, the license doesn't cover you to use or publish the assets in new projects. Your license covers the projects that are created and published during your active subscription term. This includes projects like intros and outros, which can't be used or published in new videos without an active subscription.
When you use a valid license to create and publish a project, you can keep your project in the same media and monetize it forever, even after your subscription ends.
To create and publish new projects after your subscription expires, re-subscribe to an active plan.
