SVT-AV1 1.4 & Rav1e 0.6 Released For Open-Source AV1 Encoding
SVT-AV1 as the AV1 encoder originally developed by Intel engineers and focused on delivering stellar x86_64 encode performance continues getting better.
With SVT-AV1 1.4 there are changes to yield higher compression efficiency, the M0 to M12 presets have been re-tuned using the gained coding efficiency for improved quality vs. cycles trade-offs, command line parameter handling improvements, and a variety of bug fixes and other maintenance work.
SVT-AV1 1.4 is available for download from GitLab. It will be fun to see how well SVT-AV1 1.4 is now performing on various Intel and AMD CPUs.
Also out today is Rav1e 0.6 for this Rust-written open-source AV1 encoder. As it's been over one year since Rav1e 0.5 there is a lot in store though the v0.6 change-log has yet to be completed. Expect more performance tuning and an assortment of other optimizations to be found with this updated Rav1e encoder. The project tracker notes a number of clean-ups, AArch64 NEON tuning, speed-ups, and more.
