HP Takes Z240 to 4.2 GHz; Makes Entire Workstation Line More Mac Friendly

One of the reasons I favor HP workstations is because HP practices the Japanese art of kaizen, or continuous small improvements. A great example is the recent update to HP’s entry level desktop tower, the Z240 (on the left, click to see full rez picture), which has been upgraded to accept CPUs running at up ...Read more

Per-Title Encoding: It’s Everywhere!

Netflix started the per-title encode optimization revolution in December 2015, and now per-title encoding is showing up in more and more places. Why? Because it improves the quality of hard-to-encode videos, and saves bandwidth costs on easier-to-encode videos. If per-title optimization is not available in your encoder or encoding service, it's time to start demanding ...Read more

How to Use Objective Quality Measurement Tools

Every compressed file involves dozens of configuration-related decisions, including resolution, data rate, H.264 profile, VBR or CBR, entropy coding technique, x.264 preset, b-frames, reference frames—the list goes on and on. Most encoding prof

Book Excerpt: VBV Buffer Explained

One of the topics I'm addressing in my upcoming book is the VBR rate control model, a very complicated concept. Here's the section in the book, which I'm making available for comments, corrections, and clarifications. I'm pretty sure the technical details about how the model works is correct, but I'm guessing the description and definition ...Read more

The Four Pillars of Video Encoding

 Figure 1. The four critical aspects to consider when encoding a file.Executive Summary: While video quality is always top of mind, consider deliverability, compatibility, and playability before finalizing your encoding presets. Too often we look at video encoding with a single point of focus; achieving the best possible quality for the lowest possible data rate. However, ...Read more

Fine-Tuning Your Adaptive Encoding Groups With Objective Quality Metrics

Click below to download the presentation or to view the conference video. Here's the description. Choosing the number of streams in an adaptive group and configuring them is usually a subjective, touchy-feely exercise, with no way to really gauge the effectiveness and efficiency of the streams. However, by measuring stream quality via metrics such as PSNR, ...Read more
