surprised how much faster (preset 10

<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

<br>

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>

I also noticed this post 1 (yr. ago) on reddit, "SVT-AV1

<br>
So, regarding my initial "FHD (yuv422p10le)" below,
where the audio was lost during transcode from .mov to
AV1 .webm:<br>
I have tried to interpret and experiment with FFMpeg's
"Selecting streams with the -map option" <a href="https://trac.ffmpeg.org/wiki/Map" rel="noreferrer noreferrer noreferrer" target="_blank">https://trac.ffmpeg.org/wiki/Map</a><br>
<br>
ffprobe tells pcm_s24leand 16 channels in the Audio
stream of the PreRes input file hd01.mov:<br>
<br>
<font face="monospace"> Stream #0:0(eng): Video: prores
(HQ) (apch / 0x68637061), yuv422p10le(tv,

</font><br>
VLC playback the audio ok for the input file. So I tried
a similar stream map for transcode, but without success:
Still no audio.<br>

<br>
The hd01.mov 10-bit input file was initially back in 2016 recorded
directly from my Sony HDV camera via HDMI out to a BM Hyperdeck
shuttle 2.<br>
The camcorder has only stereo audio so I think the other streams may
be empty, yes.<br></div></blockquote></div></div><div dir="auto"><br></div><div dir="auto">You can always try and load file into cinelerra-gg and see where audio was .... i think.</div><div dir="auto"><br></div><div dir="auto"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div>

VLC was not able to playback audio in 2016 from the ProRes.mov file,
but does it fine now, while not from the av1.webm file. Attach a VLC

"-map_channel", stereo if two, etc.). Using "-ac"

Maybe, if I explore BM Hyperdeck Shuttle to work again later on and
