H.264 screen capture hits ~1500x PNG efficiency: 5s 60fps video in 175KB vs 1015KB per PNG frame

A hands-on measurement using the Apple homepage: a 5-second 60fps H.264 capture came out to just 175KB, while a single frame exported as PNG weighed 1015KB — meaning roughly 300 frames of video at one-fifth the size of one PNG, implying about 1500x PNG efficiency. The author notes the mechanism: H.264 is a lossy codec that discards less important detail rather than zeroing regions. Useful reference for screen recording, remote desktop, or compressing visual training data.
