Flat design animation - factory exterior and conveyor belt

I am working on a project using the flat design animation look and I’m looking for a factory animation in this style.

I’m sure I’ve seen one on videohive that is an exterior of a building with a conveyor belt either side that has boxes going in and out of the building, but I can’t find it now.

If anyone knows of something similar to this it would be a huge help. Many thanks.
