B-Frames, Ultra Low-Latency Encoding, and Parking Lot Rules

One of my sweetest memories of bringing up our two daughters was weekly trips to the grocery store. Each got a $5.00 bribe for accompanying their father, which they happily invested in various tchotchkes that seldom lasted the week.

AV1 or HEVC: The Next Big Codec Decision

Codecs are tools we use to reach our viewers. So, when it comes to codecs, the best ability is play-ability, or the ability to play on the target platforms our viewers prefer to watch. For years, H.264 has remained dominant simply because it played everywhere; but as videos grow larger, faster, and deeper in color, the cost of distributing H.264 …
