MPV Image Testing

[Sound Master]

I made some images using mpv. Can you tell the difference from the png files to the other files? Also, does mpv use ffmpeg to extract frames?

The PNG and AIFF are identical. The rest different.

How about this jxl file?

[jagabo]

That is identical to the PNG and AVIF. A few caveats, I'm comparing all as 8 bit (per channel) RGB using AviSynth.

v0 = LWLibavVideoSource("mpv-shot0001.png", cache=false, prefer_hw=2, format="RGB24") 
v2 = LWLibavVideoSource("mpv-shot0001.jpg", cache=false, prefer_hw=2, format="RGB24")

Subtract(v0, v2)
Levels(127,1,129,0,255)

Aside from ffmpeg I don't have tools that deal natively with jxl. So I use ffmpeg to convert the jxl images to png before comparison:

ffmpeg -i input.jxl output.png

Which one was the least lossy, the small jxl, the jpg, or the webp file?

Is this jxl similar to the png file?

Which one was the least lossy, the small jxl, the jpg, or the webp file?

By what criteria? Why not just look at them and judge for yourself?
