Okay, I finally found a word for what I would like to have/learn how to use: a capture card. This is what other people use to capture game footage.
Yes, a capture card is what was traditionally used to capture video...in the old days. Today, capture cards are still used on high-end video production desktop computers, where the capture card goes in an expansion slot in the desktop case.
But you don't have a desktop, you have a laptop. Today, very few laptops still have expansion slots, and you'll have a hard time finding anyone making video capture cards for any laptop, Windows or Mac.
Just about everything that used to be made as a capture card is still available, but in a different form, usually an expansion module that you plug in via USB or Thunderbolt.
The video capture cards for Windows and Mac laptops are now generally available as USB sticks. You plug one end into your video and the other into the USB port.
The ElGato EyeTV is pretty much what a video capture card is on a Mac these days, so we have now circled back to that. It is the same guts as a capture card, in the form of a USB module. Which is great, since if it still looked like a plug-in card you wouldn't have anywhere on the laptop to plug it in. As a USB module it works with any Mac, slot or not.
There are high-end video capture cards available for Macs, but they are expensive cards for the expansion slots in the Mac Pro desktop.
