6. Display resolution standards - Wikipedia

   en.wikipedia.org/wiki/Display_resolution_standards

   One drawback of this resolution regarding encoding is that the number of lines is not an even multiple of 16, which is a common macroblock size for video codecs. Video frames encoded with 16 × 16 pixel macroblocks would be padded to 640 × 368 and the added pixels would be cropped away at playback. H.264 codecs have this padding and cropping ...
