This case study compares CAPEX, power consumption, and co-location costs for GPU, CPU, and ASIC-based transcoding.  This case study was derived from Ilya Mikhaelis‘ recent talk at NETINT’s symposium on Building Your Live Streaming Cloud. Images have been consolidated and modified slightly. You can view Ilya’s talk and download his slides here: bit.ly/vovs.   Ilya Mikhaelis is the streaming backend tech …

Learn to use Capped CRF with SVT-AV1 and FFmpeg for live transcoding, including how capped CRF compares to VBR and CBR. All tests and results are available in downloadable PDF. Capped CRF is an alternative to VBR and CBR that saves bandwidth on easy-to-encode sequences and preserves quality on hard-to-encode sequences. Our tests with SVT-AV1 and FFmpeg show: Performance: Capped …

There are four bitrate control techniques worth considering for live encoding/transcoding using the SVT-AV1 codec. These are: Capped CRF VBR Capped VBR Constrained VBR Here’s what I found: Overall: Capped CRF shows promise with significant bitrate savings, good quality retention, and the best overall performance by ~10 – 25% (meaning more streams from the same hardware). VBR was generally the …

A recent review from The Ohio State University’s Derrick Freeman highlighted what he learned from Streaming Media 101. Below is his review, which I’ve chopped up into bullet points. “I just recently earned my certificate from Jan Ozer’s “Streaming Media 101: Technical Onboarding for Streaming Media Professionals” e-learning course at Streaming Learning Center. I was amazed at how much I …

I was raised in a beachfront commuter town about 60 miles south of Manhattan and five miles north of Springsteen’s Asbury Park. I went to Seashore Day Camp years 8-13, swimming laps in the pool each morning and clowning around in the ocean each afternoon. I spent middle school and high school in the Atlantic as often as possible, swimming, …

Telestream resurrects encoding.com’s Global Media Format Report to provide valuable data on codec usage and other production details.  For years, encoding.com’s Global Media Format Report provided a key set of data points on codec usage and other topics from the prior years encoding production. Since encoding.com was the first and remains one of the largest cloud encoding providers, this data …

This article provides a quick reference for video codec details from H.264 to LCEVC, excluding EVC, because so little progress has been made on productization. Codec Overview Starting at the top, the year released emphasizes how long H.264 has remained the dominant codec, as evidenced by ReThink’s 2023 usage rate of about 72%. Browser penetration, as measured by CanIuse, is …

Recently I was asked to visually illustrate the data rate difference between two HEVC files, one encoded with CBR at 6 Mbps, the other using capped CRF with the same cap. Of course, everyone’s go-to bitrate visualization viewer has always been Bitrate Viewer, which does a great job displaying the bitrate of a single H.264-encoded file. Unfortunately, it can’t input …

I’m proud to speak at NETINT’s Build Your Own Live Streaming Cloud Symposium. We’ve assembled an all-star cast of experts to educate streaming engineers on how to build their own encoding and packaging infrastructure and save a bundle over cloud services.  Speakers include representatives from Wowza, GPAC, id3as (Norsk), Edgio, Greening of Streaming, two of us from NETINT, and two …

Just a quick announcement to let you know that if you’re taking a course on the Streaming Learning Center, you can now access lessons via a mobile app. By way of background,  we use a learning management system called Thinkific to host all Streaming Learning Center courses. Thinkific recently launched its new mobile app for iOS and Android that we …
