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 with metrics such as CRF, PSNR, Spherical PSNR, Weighted Spherical PSNR, and VMAF, you can assess the quality delivered…
Reaching multiple viewing platforms with a single live video stream used to be impossible, but not anymore. Here’s how to do it with Switchboard Cloud. Live content can be extremely engaging, and oftentimes, the more you spread it around, the better. This means streaming to accounts you have access to, and also to accounts controlled…
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,…
I’ve resisted upgrading to the latest version of Adobe Creative Cloud because the beloved titler has been replaced (but is still available). After producing a video tutorial on the new title function for Streaming Media Producer, I see that Adobe made a great decision; the new tool is both more capable and more accessible. The…
It took awhile, but the first review of my book, Learn to Produce Videos with FFmpeg: In Thirty Minutes or Less, is up on Amazon. Here’s the key comment. “Everything here is already available on the net. But this is much easier. Worth the price just to have it all in one place. Easy to read…
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…
Just back from Streaming Media West in Huntington Beach, where I participated in seven presentations over three days. Handouts are up and ready for your download, and the videos are up as well. Three of these presentations, on FFmpeg, HEVC/HLS, and latency, were co-produced by David Hassoun and Jun Heider from the RealEyes consultancy, which serves clients like…
I’ve been bullish on AV1 since the start, but I’m starting to think the codec is both farther away and less useful than I initially thought. Here’s what’s happening. For Streaming Media East in June 2017, an AV1 member encoded four videos, totaling about 8.5 minutes, to five data rates each for 720p, 1080p, and…
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…
Here’s the description: download handout below: Per-title encoding techniques customize the encoding ladder to match the encoding complexity of the source, saving bandwidth on easy-to-compress videos and ensuring the quality of more complex footage. This session compares the efficiency, implementation issues, and costs of multiple commercially available and open-source alternatives, like Capella Systems Cambria Encoder,…
