[theora] NHW Project - new -l19 "extreme" compression quality setting
Hello, For those interested, I have added a new -l19 "extreme" compression quality setting to the NHW Project.This -l19 quality setting is really competitive with x265 (HEVC) on rather good quality images. An important remark: we can really save 2.5KB in average per .nhw compressed file as the entropy coding schemes are not optimal, especially at extreme compression.I have the fast ideas to improve it.Will have to do it. More at: http://nhwcodec.blogspot.com/ I will have to study a little deeper the psychovisual model I use for extreme compression, because on 5% of the images, certain kinds of images, it is better to switch it off... Again, it would be great if you could consider the NHW Project as furthermore it is royalty-free and ultra-fast, I know it is impossible to compete with VP9,HEVC, AOM AV1, VVC, but maybe there would a niche these codecs don't cover and where the NHW Project could shine, because I feel it still lacks of consideration by the industry (but of course this is only my opinion)... Many thanks! Cheers, Raphael -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.xiph.org/pipermail/theora/attachments/20190217/6dc7ffb6/attachment.html>
