If SVT-AV1 1.8.0 rendering is possible with cin-aom-38_svt.AppImage, where
do you select this?
Among the webm presets should also appear av1-svt.webm, the profile
created by Andrew; see image:

Yes, thanks I found it. I had not looked there or simply overseen
it, as it normally is referred to as svt-av1 :)
And SVT-AV1 1.8 confirms to be VERY FAST and of most interest as
default CPU AV1 encoder (also for CinGG?)
As mentioned in Phoronix recent release article:
https://www.phoronix.com/news/SVT-AV1-1.8-Released
SVT-AV1 1.8 brings more speed-ups at various preset levels --
especially M0 to M6 where there can be gains as much as 53%.
Two Cin-GG AV1-SVT rendering tests of the same loaded hdv07_05.m2t
clip took 0:02:54 and 0:02:51 respectively.
If not due to technical issues (see the attached messages), that
is impressive FPS = 10240/172 = 59.5 or 2.4x faster than the clip
duration!
And compared to the AOM 3.8 40-minutes rendering above, this is
14.3x times faster!
The CinGG svt-av1 v.1.8 preset seemed to use Preset 6 and CRF 26
In comparison I started a temporary test with the same FFmpeg
SVT-AV1 v. 1.7 Preset 6, which seemed to perform much slower (ca.
8 FPS).
The default faster Preset 10 and CRF 35 from my previous FFPmpeg
test of the same clip provided 68 FPS.
That is, very Promising SVT-AV1 speed rendering, BUT
the HDV Aspect ratio and broken Audio has to be fixed in CinGG
yuv420p(pc, smpte170m/unknown/unknown), 1440x1080 [SAR 1:1 DAR 4:3]
Or the procedure has to be clarified, in case I have done
something wrong or inadequate.
for aspect ratio I just send out patch hopefully fixing this.
For audio - try opus/webm as audio encoder?
For colorspace - set it to bt709 as illustrated here
https://cinelerra-gg.org/download/CinelerraGG_Manual/Color_Space_Color_Range_Aff.html
While waiting for a patched aspect ratio version, I've tried the other
suggestions:
opus/webm audio encoder
Colorspace bt709
This fixed the audio issue and extended the file size and rendering time
with 50%
