Of many competing services offering online digital assets, Story Blocks is most famous. And advertises the most.
But I was convinced to join instead less expensive Envato Elements US $198 / year. Both work with Final Cut Pro, my software.
They provide licensed images, audio, videos, graphics, plugins, fonts, logos, tutorials, 3D, graphic & video templates, presentation templates, infographics and much more. I’ll be including those in my videos, websites and presentations.

One of the main things I like about using their digital resources is the simplicity of licensing. I’m much less worried that YouTube — sometime in future — might take down my YouTube due to copyright complaint.
