One tool that offers a free introduction to try is Educreations . It allows you to create and share videos with your students. It is user-friendly and now has the capability to be shared on Google Classroom and Remind. This is especially ideal for a flipped and self-paced classrooms, as well as distance learning. The drawback is there is not too much storage on the free version, maybe a couple videos at most.
