Bad math (Score: 1) by email@example.com on 2015-06-13 21:41 (#B6Q9) The VP9 codec can reduce the bandwidth needed to play a video by up to 35 percent, according to Google. This means that a user who was previously relegated to watching 480p video should now be able to watch 720p, for example.No, it means no such thing. 480p -> 640x480 -> 307,200 px; 720p -> 1280x720 -> 921,600 px. Both are the same framerate. So 480p is not 65% of the bandwidth of 720p, it is 33.3%.

You're using uncompressed numbers, while video compression does NOT scale-up linearly like that, at all. It does NOT take 4X the bandwidth just because the picture has 4X as many pixels. I generally ballpark a doubling of frame-rate or resolution as a 50% increase in bandwidth, and it's quite possible to do better.

Re: Bad math (Score: 1) by firstname.lastname@example.org on 2015-06-14 04:35 (#B79T) So how about explain how it's a fail instead of just throwing out condescension. Educate the poor guy/gal!
