Kwag why have you changed the values of mergechroma and mergeluma in the letest script. Changed from mergechroma(blur(1.58 )) , mergeluma(blur(0.3)) mergeluma(blur(0.2)) and mergechroma(blur(1.5))

Not so familiar to luma and chroma

Probably because people thought the old values blur the image too much... ...I had no problem with the old values though, so I still use them. If you don't see any problems with the old values, keep using them. You'll get at least a bit more compression.

Depending on the sourse i use MergeChromaBlur(0.2)) up to (4.5)) for compression because it helps when you have Dynamics 1-2 settings on your player.

I dont think I've seen any scene how was blurie when I used the old values. But were can you usually see blur, I'm mean, can you see it on walls, peoples, smal diatails...You have to point me in the right direction

I had a movie that with 1.58 on chroma, I saw a color "bleed" on some edges. But when I lowered to 1.50, that cured it. So maybe 1.58 being the maximum value, causes an excess saturation on some chroma levels ( That's what I think that happened! )
Anyway, I just lowered the value to 1.50 for safety, and dropped the luma from .3 to .2 for a small sharpness increase.

I think it just means the colour smears over the edges a bit.
