svt av1 s evolution part 1 presets analysis from v2 0 to v3 0 june 20 2025 241 min read trix encoder it s been almost a year since svt av1 v2 0 0 dropped in march 2024 and we finally got v3 0 0 in late february of this year minor versions v3 0 1 and v3 0 2 came along afterward with some bug fixes and arm simd improvements but they didn t meaningfully alter encoding results so what s actually different between these versions i ve been wanting to run tests across all the major releases from v2 0 0 to v3 0 x to see how the speed vs quality trade offs have evolved this past year using ssimulacra2 butteraugli xpsnr and vmaf plus some methodology tweaks i ll get into i ll break down what each version brought to the table and in a second part we ll also deep dive a few specific options that appeared in the encoder since my first blog post release so you can figure out what you may want to use for your projects that includes variance boost fast decode temporal filtering strength and a few others tags video compression benchmarks read more fast computation of ssimulacra2 on gpus a performance evaluation november 21 2024 24 min read bolu novice encoder programmer in this blog entry we will evaluate the performance of turbometrics a software which provides a gpu accelerated implementation of ssimulacra2 and promises to save a lot of time in its computation tags video metrics benchmarks read more better late than never svt av1 v2 2 x deep dive november 14 2024 160 min read trix encoder svt av1 v2 2 0 was released in late august and a minor version v2 2 1 followed suit to adress some bugs this blog post will focus on comparing this new encoder version to the last on the basis of benchmarks and visual comparisons we will quantify the new trade offs between compression efficiency and encoding speed so you can choose the right balance for your projects our metrics of choice today will be ssimulacra2 and xpsnr used in conjonction with a revised

scalable av1 encoder has received a new update and one may wonder if the old presets recommendation still holds today we will delve into that in this blog post based on a series of speed and visual quality benchmarks with ssimulacra2 and xpsnr of svt av1 2 1 0 on a corpus of varied animated clips tags video compression benchmarks read more encoding animation with svt av1 a deep dive december 30 2023 35 min read trix encoder this blog post is based on a series of visual quality benchmarks with ssimulacra2 and speed benchmarks of svt av1 1 8 0 on a corpus of animated clips the resources available will range from graphs to image comparisons wip the former has the advantage of being easily understandable showcasing pure efficiency comparisons between encoder parameters using metrics as the reference while the latter are image samples from the encoded files during the tests that enable you to check quality for yourself and add another layer of subjective interpretation to these
