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 it.  OK, perhaps the title …

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

Publishers and encoding companies alike are beginning to embrace VP9, Google’s open source codec. Here’s how it stacks up on quality and data rates. The value proposition for VP9 is clear, as stated in Figure 1: “Adaptive HD streaming with 1/2 the data of H.264!” Half the data rate cuts your bandwidth and storage costs and allows you to reach …
