The game featured in the split-second previews at the end of the tape called Kirby's Air Ride was never released for the Nintendo 64. A revised version, however, did appear on the Gamecube.
The split-second previews at the end of the video feature clips from an early version of Zelda: Ocarina of Time, back when the game was still called Zelda 64. You can see many locales in this preview that didn't make it into the final game.
