what for code names :D

Thanks for the info. I don't like codec, because it is very slow work. Codec doesn't want convert image 5K.

you will endup with higher computational cost

while Guetzli creates smaller image file sizes, the tradeoff is that these search algorithms take significantly longer to create compressed images than currently available methods.

pretty much since HEVC this explodes now and will further explode.

Isn't it in Schwiizertüütsch? I mean named after a Swiss bakery product like Brotli or Zopfli (also used by Google for name of compressors)?

[CruNcher]

Yeah that made me lough after donuts, ice cream sandwiches, gingerbreads, froyos, cupcakes, lolipops, honeycombs, jelly beans and such "sweet" code names this continues multilingual now it seems :D

in this case their Europe R&D Swiss taken over :D

Nothing really unexpected optimized for butteraugli ;)

though there is much more different results that can be gained from mozjpeg based on the metric used for optimization in this case what is the most interesting is butteraugli that makes the decission and how costly that is currently not guetzli itself ;)

https://github.com/danielgtaylor/jpeg-archive

can utilize different metrics for the end result of mozjpeg.

including a interpreted version of Smallfry ;)

i wonder when someone going to add VMAF and Butteraugli ;)

in Xlz example it seems to not like water at all, overall it does really bad here in motion that would be fun ;)

Totally failed processing a large 24 megapixel image...

Despite the many updates, Guetzli still has troubles with 4K photos.
