According to Phoronix the Alliance of Open Media project quietly
released (the Intel based) SVT-AV1 v2.1 last week.<br>
With this new SVT-AV1 release are yet more performance
optimizations and tuning. <br>
The M0, M3, M5, and M6 presets are seeing 12~40% speed-ups while
maintaining similar quality levels to prior releases. <br>
The compression efficiency of presets M11 to M13 meanwhile have
improved by 1~2%.<br>
New SVT-AV1 benchmarks soon.<br>

Meanwhile, I have updated my previous tests using ffmpeg-7 and
libSvtAv1Enc2 version 2.0 on openSUSE Slowroll below.<br>
The results are about the same speed +/- compared as my earlier
tests using ffmpeg-6 and SVT-AV1 encoder version 1.7<br>

(Else I have purchased the hardware components to upgrade and
rebuild my workstations for a planned AV1 QSV/hw video
transcoding:<br>
mobo, Intel cpu and gpu, memory, ssd, cooler. More about this
later. But first I have to finish my ongoing DVD Video project).<br>

With my own new and faster hardware in box running a matured and
updated openSUSE Tw Slowroll (system overview at the bottom here), I
have updated and extended my own transcoding tests using ffmpeg-7
and SVT-AV1 v. 2.1.<br>
<br>
For SD DV 576i -> AV1 the speeds increase from fps=50 at preset 4
up to fps=890 at preset 12, compressed file sizes 6-8% <br>
For HDV 1080i -> AV1 the speed increases from fps=24 at preset 4
up to fps=376 at preset 12, compressed file sizes 16-18%<br>
