The latest Construct updates and browser updates have made possible some interesting new improvements for both video support and images. We wanted to highlight...
I've just done some image tests with Gimp (it supports all these formats) with Avif and Jxl in maximum quality, real tests because I looked at the pixels with a zoom * 8 on each image, original, Avif and Jxl, conclusion:
Jxl in first position
Avif in 2nd position
Both without loss (in any case no difference even with 800% zoom, same colometry too.
Then there's Webp in position 3, also lossless.
As for loss, I haven't really looked, it's difficult to judge because there are so many parameters to take into account, so when I judge a codec, it's on maximum quality, but it's true that they're very good.
I don't know how they manage to make such high-performance codecs, but it's incredible.
