webmproject / codec-compare Goto Github PK

Hello,

I must say your representation is a bit hard to follow for a novice :D

When you look at this page : https://storage.googleapis.com/demos.webmproject.org/webp/cmp/2024_01_25/index.html?load=jpegxl_vs_avif.json#ref=AVIF+speed+6

avif seems to have the lead over jpegxl at every efforts

When you look at this one : https://storage.googleapis.com/demos.webmproject.org/webp/cmp/2024_01_25/index.html?load=all.json#WebP+method+4-quality=95..95&matcher_ssim=off

The tendency is flipped, with jpegxl taking the lead ?

Could you explain how to use your site to have a good idea on the relative performance of both codec ?

Also, it is difficult to get an idea of the quality selected as reference, perhaps a link to an image at this quality could help showing the level of distortion obtained (I guess < 0.1bpp can not seriously be used for display)

Hi!

Great project 👏

Do you have a backend sample to encode different image formats and qualities, and then generate the JSON file?
