		neo2006 on Nov 4, 2016 \| parent \| context \| favorite \| on: H.264 is Magic The comparison doe not make any sense, and no h264 is not magic!!: - The guy is comparing a lossless format PNG to H264 which is a lossy video format, that is not fair. - he is generating a 5 frame video and compared to 1 frame image, only the I-frame at the begining of the video matter in that case al the others are derived from it, P-Frame. - What is the point of having that comparaison we already have images format comparable to the size of a H264 I-frame and using the same science (entropy coding, frequency domain, intra frame MB derivation...)?

Did you read the article?

The point you are making here is PRECISELY the point that the author was making in the article: that a lossy format can be far, far smaller. He then goes into the details (from a high-level point of view) of what kinds of losses H264 incurs.
