Avisynth: mergeLuma and mergechroma?
 

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)) :arrow: mergeluma(blur(0.2)) and mergechroma(blur(1.5)) :?:

Not so familiar to luma and chroma :oops:

Probably because people thought the old values blur the image too much... :roll: ...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. :wink:

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 :lol:

Re: luma and chroma
 

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 :idea: ( 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.

How does it look when a movie bleeds 8O Like blood? And were can I red about chroma and luma :?:

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