Summary When choosing an HLS or DASH segment duration for VOD video, the nature of the server/player connection is critical. For persistent connections, a segment size of two-three seconds produces good quality and optimal system throughput. For non-persistent connections, a segment size of six seconds produces the best overall throughput. With live video, if latency…
DetailsOne 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…
DetailsNetflix 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…
DetailsIf you haven’t been watching the live titling space, you’ve missed the NDI revolution, and your productions may be falling behind in terms of graphics quality. In this article I’ll explain what NDI is and how it works, and I’ll explore how it enhances the titling capabilities of the NewTek TriCaster, Telestream Wirecast, and vMix…

As much as we expect standards like HTML5 to simplify our jobs, oftentimes they don’t. In fact, a recent HTML5-related project convinced me that…
DetailsStephen Nathans-Kelly, a video producer at Streaming Media Magazine, is carving conference videos into short useful segments. Here are the first two videos on building your encoding ladder from my talk on how to use objective quality metrics you can watch in its entirety here, as well as download the handout. The first video covers…
DetailsEvery 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
DetailsPublishers 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…
DetailsOnline is different from broadcast and doesn’t need formal standards. HEVC isn’t considered by many online video streamers, as the future belongs to VP9 and AV1. Elsewhere in the issue, you find a 4,000-word article I wrote on VP9 that doesn’t mention HEVC. Why? Because for the vast majority of streaming producers that don’t distribute…
