Hello, I have just added a first draft of high compression (-l3 setting) for the NHW codec.Now it keeps still a good neatness (new -l3 setting is really better than the previous one) and it is competitive with x265, sometimes more neatness is more pleasant, sometimes it's more precision. As I have many kinds of artefacts with increasing the wavelet coeffs threshold of the dead-zone (and not only aliasing), I don't have touch then the wavelet threshold (still 8) for now, still checking the code and algorithm, maybe I will increase wavelet thereshold for higher compression settings. For those interested, see update: http://nhwcodec.blogspot.com/ Any feedback welcome. Cheers, Raphael -------------- next part -------------- An HTML attachment was scrubbed...
