The intersection of video processing and artificial intelligence (AI) delivers exciting new functionality, from real-time quality enhancement for video publishers to object detection and optical character recognition for security applications. Forward-thinking product designs incorporate both video processing (decode/scale/overlay/encode) and AI to provide the optimal platform for video-related AI applications like those discussed below.   For example, I recently joined NETINT in …

Streaming Media West was a high-energy conference with a great vibe and the usual elegance of the Hyatt Regency Huntington Beach Resort & Spa. I gave two talks; a 3-hour preconference session entitled Advanced Codec Implementation & Production and a 45-minute session on Encoding AV1 with Open Source Alternatives. Below are the descriptions and links to the presentation downloads. W1. …

This article shows the quality/encoding time tradeoffs for producers choosing a preset for SVT-AV1 and libaom-AV1. Note to readers – 12/13 – AOM has released version 1.4, which fixed the SVT-AV1 preset issues reported in the first version of this article.  Presets are the most important configuration option for controlling quality and throughput for most codecs. For this reason, when …

This article details a methodology for comparing hardware transcoders considering cost/stream, watt/stream, and output quality. If you’ve ever benchmarked software codecs, you know the quality/throughput tradeoff; simply stated, the higher the quality, the lower the throughput. In contrast, for many first-generation hardware encoders, throughput was prioritized, but the quality was fixed; you got what you got. Finding the Key Quality …

Back in high school, if someone called you dense, it meant you were slow on the uptake, and it definitely wasn’t a compliment. For high-volume video transcoding, however, density is, without question, a major plus.   Some background. I now work with NETINT, a Canadian company that designs, develops, and sells ASIC-powered transcoders like the T408 and T432, which can output H.264 and …

Four days on the show floor at IBC solidified the concept that your choice of the live encoder is dictated by your encoding application. In this article, I’ll review the types of encoders and the trade-offs associated with each type and will identify the type of encoder that works best for a few selected encoding applications. Types of Live Transcoders …

This tutorial teaches you how to install and use FFMetrics, a free tool that lets you compute and visualize VMAF, SSIM, and PSNR on up to 12 files.  Let me start this article by stating that the one program I couldn’t live without in my role as video tester and evaluator is the Moscow State University Video Quality Measurement Too …

New lessons detail how to use FFMetrics; updated lessons on what VMAF is, how to compute VMAF with FFmpeg, and how to interpret VMAF scores. Just a quick note to let you know about new additions and updates to our course, Computing and Using Video Quality Metrics: A Course for Encoding Professionals, which teaches encoding professionals how to choose and …

When I first heard that Google Chrome played HEVC, I checked the weather in Hades to determine if it had, in fact, frozen over. Reports were inconclusive. Then I started reaching out to colleagues and contacts whose opinions I value to get their reactions and thoughts. Many spoke on the record, and many didn’t. In this article, I’ll attempt to …
