> So in terms of the precision of arithmetic, I think we can assume that libjxl is more precise than the rest. More precise than mozjpeg float? I mean, when...

Actually no, my comparisons were jpeg vs jpeg -> jxl -> jpeg. I decode directly to YCbCr so the degradation is visible even without conversion to RGB. In any case,...

Can confirm. Then I will need to run my tests with RGB conversion in mind (output to png) because --strip saves some size by removing the jbrd box. And I...

No, I didn't use --strip in OP, but the issue is JXL uses a different iDCT codepath when reconstructing jpeg so it can't be used as reference. The problem seems...

> I don't understand what those two jpgs that you linked are. Hi @mo271, you asked me for the avisynth images and that's what I uploaded, to be more concise...

+1 for this. UI wise the program is pretty much covered, so after the color management was implemented this is the last bit remain. Just posting so I can keep...

Just an update to the report. It still happens on Retroarch 1.7.7 x64 (what I use) and latest cores. The game still seems to play and I can hear the...

By the way, I wanted to comment that today I was reading the crt-guest shader README, and the idea of scaling to next integer (as opposed to previous) is also...

I don't recommend you to promote the use of JPEG XL while it isn't stable yet, people is degrading their "lossless" transcodes by signaling degraded dequantization coefficients. See [here](https://github.com/libjxl/libjxl/issues/1470). Work...

I was only replying to: `Just for information: I've been using my powershell script to convert several 100'000 pictures to .JXL, (...). If there is interest I'll clean it up...
