DetailsSummary (The MPD) When distributing video under constrained conditions, the bitrate control technique used to encode the files can have a profound impact on the quality of experience (QoE). Specifically, under some conditions, CBR-encoded files deliver a superior QoE to files encoded using 200% constrained VBR, while also reducing the overall bandwidth delivered. For producers…

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…
DetailsThe move away from plugins like Flash and Silverlight has made video delivery easier, but it’s also made DRM more complicated. Here’s what DRM looks like today, along with a discussion of the leading DRM technologies and DRM service providers. If you plan to distribute premium content from the major U.S. studios, you’ll need to…
DetailsThe promise of a unifying standard to simplify our lives is attractive, but putting it into practice is another thing. Here’s how one HTML5 video project got messy in a hurry. 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…
