I&#x27;m reminded of a friends bitch about his company hiring a couple of ex-bell labs video compression guys to develop video codecs. Said they spent a year and came up with a great codec. Decode speed was twice as fast as anything else. Great!! Encoding speed was about a 1000 times slower. So encoding 5 minutes of video would take 3.5 days. And thus totally unusable.<p>The issue is design axis&#x27;s are entangled. And also figures of merit are nonlinear. Twice as whatever doesn&#x27;t mean twice as good.
