I did also notice: <br>
<br>
<i>The encoder supports a wide range of speed-efficiency tradeoffs
and scales fairly well across many CPU cores.

<br>
<i>Since SVT-AV1 is designed to scale well across cores/processors,
fast encoding is
best performed on machines with a sufficient number of threads.</i><br>
