<blockquote type="cite">I will add the re-encoded

I was positive surprised how much faster (preset 10
about 25 sec) it was than rendering AV1 with CinGG

12. "Useable visible quality" for all.<br>

<br>
The speed of SVT-AV1 encoding seems for me to be quite
useable, at least for personal use.<br>
</blockquote>
<br>
<br>
As a reference to compare the SVT-AV1 results above,
I've also tried to encode the same input file using
libaom-av1 and librav1e<br>
with simple or none (default) parameters. Other, optimal
tuned parameters may possibly change the unsuccesful
results here.<br>
Seemingly something have to be wrong here, as I had to
quit these hopeless SLOW encoding attemps after a while:<br>
<blockquote>ffmpeg -i dv01_07.dv -c:v libaom-av1 -crf 30
-c:a libvorbis dv01_07_libaom-av1.webm<br>
^C^Ze= 35 fps=0.1 q=0.0 size= 5kB
time=00:00:03.00 bitrate= 13.7kbits/s speed=0.00748x<br>
<br>
ffmpeg -i dv01_07.dv -c:v librav1e -c:a libvorbis
dv01_07_librav1e.webm<br>
frame= 471 fps=1.9 q=-0.0 Lsize= 4864kB
time=00:00:19.11 bitrate=2084.4kbits/s speed=0.0791x
<br>
</blockquote>
The CPU (i7 quad-cores 8 threads) utilization was here
between 100-200%, while I think it ran at 700%+ for
SVT-AV1.<br>
<br>
Anyway, apparently SVT-AV1 libsvtav1 shines as the
superiour fastest and simple to use CPU based AV1
encoder (before GPU hwaccels)<br>

was lost during transcode from .mov to AV1 .webm:<br>
I have tried to interpret and experiment with FFMpeg's "Selecting
