These reports identify the OPEX and quality leaders and save months of testing.  Overview: Per-Title encoding is the most efficient and effective technology …

This post explores the economic factors to consider when choosing a preset for the SVT-AV1 codec. It’s adapted from a new lesson added to the course, Encoding with the AV1 Codec. While this analysis uses the SVT-AV1 codec, it’s useful for choosing a preset for any codec.  I’ve always considered codec preset selection a cost and quality-driven decision. You see …

I’ve been testing SVT-AV1 1.0 for a presentation that I’m giving on open-source AV1 encoding alternatives at Streaming Media East on May 24, 2022. The results have been impressive; two-pass VBR encoding is working well, and the codec offers a great range of presets, with several much faster than real-time. In contrast, FFmpeg’s libaom-AV1 has no presets even close to …
