While low-latency transcoding sounds desirable, low-latency transcode settings can reduce quality and may not noticeably impact latency. Reducing latency has been a major focus for many live producers, and appropriately so, particularly for events that viewers can watch via other media, like sporting events available through satellite or cable TV. However, it’s important to understand that transcoding latency contributes minimally …

Recently I was asked to visually illustrate the data rate difference between two HEVC files, one encoded with CBR at 6 Mbps, the other using capped CRF with the same cap. Of course, everyone’s go-to bitrate visualization viewer has always been Bitrate Viewer, which does a great job displaying the bitrate of a single H.264-encoded file. Unfortunately, it can’t input …

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.
