Back in 2001, a guy called David Dries created www.cinemacade.com and some fantastic MAME fan videos.
Skip forward nearly 20 years and I have upscaled three of the videos to 1440p, 60fps smooth motion.
The videos were converted with https://www.convert-it.org
 
You can find the original cinemacade.com website here:

The videos can be used as system logos or startup videos.

GameEx - HTPC Gaming Front end.
 
The GameEx frontend.
Latest version.
Full install.
 

GameEx Arcade Edition is a derivative version of GameEx that is optimized for arcade controls, arcade machines, and HTPC systems where only gaming is wanted. It was originally designed for arcade game setups only but also supports any emulation system.
It is lighter, has cosmetic improvements and supports the new EmuMovies video themes.
It supports MAME, arcade systems, all other systems and has the following feature differences over the normal GameEx version.
Supports video themes. Less code. Lighter. Less options. Optimized cosmetics for TV and arcade displays. Good support for low resolutions (640 x 480) out of the box. Does not look like windows. Does look a little like HyperSpin.  
The video themes and all the content is available at EmuMovies and an automatic downloader is included with the front end.
Don't forget that GameEx subscribers get a 25% discount on an EmuMovies subscription.
Alternatively, subscribing users can use the MAME system pack:
