Hello,<br>
<br>
Just a quick message to let you know that I have really improved very high compression of the NHW Project <br>
from -l8 to -l13 quality settings, and we can still save 2.5KB per .nhw compressed file.<br>
<br>
Actually I am new to very high compression, it is just 3 months that I am<br>
working on it (I put on pause the NHW Project from August 2013 to February<br>
2018 )... And I realize that very high compression is quite difficult<br>
because all the noticeable artifacts appear there... With this update, my<br>
new -l13 very high compression quality setting is really better, and can<br>
compete with x265 (HEVC) on rather good quality images, because it has more<br>
neatness, but that's right that on "degraded" images (compressed, with<br>
artifacts), HEVC starts to excel and be very impressive.<br>
<br>
I find that -l13 very high compression setting is the limit where the other<br>
codecs (WebP, x264, Rududu,...) start to perform less efficiently and have<br>
noticeable quality drop, whereas HEVC stays excellent... I will try to<br>
improve the NHW Project so that it stays competitive with HEVC on all type<br>
of images at -l13 very high compression, and not on good quality only... but it is not that easy as I want<br>
the NHW Project to be very fast, and stay at least 50x faster to encode and<br>
at least 15x faster to decode than x265 (optimized HEVC), and also stay<br>
royalty-free!<br>

Any opinion on the NHW Project is very welcome!<br>
<br>
Many thanks for your time.<br>
Cheers,<br>
