<br>
Seemingly this is a minor bug somewhere in this
version.<br>
I upgraded my system SVT-AV1 and lib to v. 2.2.1 and
got the same result: 2.2.0<br>
<br>
What confuse me more, is that Cingg rendering seems <span><a
rel="noreferrer noreferrer" moz-do-not-send="true">out
of proportion</a></span> 2.5x faster than
corresponding transcoding the same hdv file using
ffmpeg directly. Possibly Cingg calculates the speed
after loading the input file, and ffmpeg not(?)<br>

<br>
Thank you. Yes, with parameters "preset 6" and "crf 35" the
Cingg/FFmpeg rendering speed matched:<br>
<blockquote><font face="monospace">Cingg: ** rendered 5972 frames
in 84.437 secs, 70.727 fps<br>
</font></blockquote>
At first I wondered if perhaps different CPU core utilization had
been used above. I verified now with top that Cingg used CPU
1400-1500% on a 12-core (8-mt/4-st) model: 12th Gen Intel Core
i7-12700KF.<br>
<br>
I also had a look back into our January conversation about SVT-AV1
parameters. As already seen above, Cingg output what I think are
SVT-AV1 defaults<br>
<blockquote><font face="Courier New, Courier, monospace">Svt[info]:
SVT [config]: BRC mode / rate factor : CRF /
35 </font><br>
</blockquote>
Therefore I suggest that the Cingg preset make use of the same
SVT-AV1 defaults, to avoid confusing.<br>
<br>
Another suggestion from the Simple SVT-AV1 Beginner guide, is to
always use 10-bit encoding:<br>
<a class="moz-txt-link-freetext"

moz-do-not-send="true">https://gist.github.com/BlueSwordM/86dfcb6ab38a93a524472a0cbe4c4100</a><br>
<ul>
<li><font face="Times New Roman, Times, serif">I always
recommend to use 10-bit (<code>-pix_fmt yuv420p10le</code>)
no matter what. It provides a good quality boost in all
cases, particularly in darker shades and noisy stuff.</font></li>
</ul>
I tested this yuv420p10le pixel format with Cingg too (no
yuv42210le pix_fmt supported by SVT-AV1 yet): <br>
Result: 10-bit a bit slower rendering and smaller file size, both
my samples looks good in my eyes.<br>
