If the author truly wants 'magic', how about we take a 64KiB demo that runs for 4 minutes. That's 64KiB containing 240 seconds of video, and your H.264 had to use 175 for only five seconds on video.

We can conclude that 64KiB demos are at least 48 times as magical as H.264.

The PNG size seems to be misrepresented. The actual PNG is 637273 bytes when I download it, and 597850 if I recompress it to make sure we're not getting fooled by a bad PNG writer.

So instead of the reported 916KiB we're looking at 584KiB.

This doesn't change the overall point, but details matter.
