Edit: Ignore my previous post: there's more tightly coupled dependency than there should be, but I've rewritten those dependencies to work properly. Someday, I should really abstract some of the logic more cleanly... Someday...

Okay, I added a couple of new options in the layout options section: you can now allow videos for the background, the carousel (conveyor), both, or neither:

I shouldn't have assumed that not everyone wouldn't want videos in the conveyor or background!

Also, I added a 16:10 aspect ratio, just because. Archive attached here, and I'll reattach to OP, too.
