While at NAB, I freelanced with my iPhone X, a video light, and a handheld microphone and interviewed 14 encoding professionals. These videos are posted on Streaming Media website along with text transcripts. Here are links to and brief descriptions of the interviews: Netflix’s Anne Aaron, on Netflix’s plans for the AV1 codec. AOMedia executive (and Microsoft employee) Gabe Frost, on …

From a Streaming Media perspective, NAB 2018 was all about the launch of the AV1 codec from the Alliance for Open Media. While at the show, I spoke with many different people from many different companies about the launch, and about other codec-related announcements at the show. You can read all about that in my article entitled, NAB Roundup: The …

Just a quick note to let you know that I’ll be speaking twice at NAB in Las Vegas next week; once as host of a panel discussion on HEVC and AV1, the other a session on how to use objective quality metrics to assist encoding configurations. Details are below. If you’re at NAB and free, and the topics are relevant …

With streaming video data rates, less is always more, unless of course, lower data rates mean visible artifacts. I just finished a review of the ZPEG Engine for x264, which produced bitrate savings of 21% without blocks, banding, mosquitoes, or other problems that would be noticeable by typical viewers. This was an average saving; the data rate reduction in some …

Moscow State University’s Video Quality Measurement Tool was already good. Enhancements in the new version, including new metrics and the ability to run multiple analyses simultaneously, make it even better. Moscow State University’s Video Quality Measurement Tool (VQMT) has always been one of the least expensive and most functional quality measurement tools available. The latest updates (10.0 and 10.1) add …

Now that programs like Wirecast and vMix make it simple to perform side-by-side interviews like my recent interview with Beamr’s Dror Gill below, I’ve been doing more of them. The tension has always been regarding video quality. Specifically, do I connect a camera to my HP notebook, or go with its internal webcam or my aging Logitech C615 webcam. Even …

The skinny: Apple, a member of the MPEG LA H.264 and HEVC patent pools, and staunch supporter of standards (and avoider of open source-codecs) broke ranks and joined the Alliance for Open Media. Give me more: Apple has always deployed standards-based codecs, and Steve Jobs was very negative on Google’s VP8 open-source codec when launched. Alliance for Open Media (AOM) …

I’m so excited to be at Stockholm speaking at Streaming Tech Sweden. My keynote address is entitled Codecs in 2018 and Beyond, and I discuss the future of H.264, HEVC, VP9, AV1, PERSEUS and Divideon xvc. The event producer, Eyevinn Technologies, has graciously approved my publishing the handout, which you can download below. Here’s the video on YouTube. Streaming Tech Sweden_Ozer_final

Here’s the description; download the handout below. C203 – How To: Reducing Latency and Startup Times Low latency and fast startup times are KPIs for most streaming video producers, particularly for live events. Though a series of structured tests that measure startup time, latency, and network overhead, this session documents the results achieved by reducing fragment sizes, using hybrid fragment …
