I find this -l13 quality setting very competitive (I will maybe use some of its processing to improve -l12 setting).Compared to x265 (HEVC), I have tested on 15 rather good quality images, and I visually prefer the results of the NHW Project because it has more neatness. Some technical details for this setting, I wash out details even more and on the other hand I use these bits to still maintain a good neatness/sharpness for edges/contours. More at: http://nhwcodec.blogspot.com/ Also, as the nhw decoder is very fast, I could add to it a post-processing function that will detect and remove aliasing (as the NHW Project can have aliasing), but it is not that easy to detect and only detect aliasing... Any suggestion would be very welcome! Again I would be really interested in any opinion on this -l13 very high compression quality setting that I find very competitive! Many thanks!
