I had AI generate Mario Kart DS gameplay. It started off with a screenshot of Mario Kart DS, and it built off from there. As you can see, the farther the video goes, the less it actually looks like Mario Kart DS.
I generated this using the Luma Dream Machine, hence the watermark in the top-left corner. You can use it here: https://lumalabs.ai/dream-machine/cre...
Please note: The audio was not generated by AI, only the video was. The music and sound effects were added in by me.
