It's generally called 'Attract mode', and at least from what I recall from the golden era arcade games (from the mid '80s up until the mid '90s) it's never an intro video, rather something done completely in-engine. Unless you're thinking lasergames, but that's ... all video.

You must mean https://en.wikipedia.org/wiki/American_Laser_Games , which uses the random-access capabilities of a laserdisc player.

I believe its the general term for games which were pre rendered/animated as opposed to being sprite based or rendered during game play. The most common wxample I recall is probably https://en.m.wikipedia.org/wiki/Dragon%27s_Lair_(1983_video_...
