Yes, I was expecting "a technical walkthrough" of how H.264 managed to improve on its predecessors. There’s nothing specific to H.264 in the article.

MPEG-2 and JPEG are very similar in philosophy as well.

JPEG in particular is still my favorite image encoding technique. Mostly because of how fast it is relative to the competition.

Even earlier with H.261 and MPEG1 which already used block coding motion no ?
