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.
