[INFO] Color luminance of old videos

[Doom83]

Usually import on hybrid some clips from movies around 2000/2005, seems there are a strange light fog/luminance, try to tweak with contrast and luminance but dont go away very much...so movie appear not very natural...whats that? Halos?

[Selur]

unnatural colors could be caused by:
a. intended color grading
b. messed up color conversion (pc vs tv, from matrix used for YUV<>RGB), which nobody cared about
c. wrong/missing flags for color matrix, luma scale (Hybrid will simply guess when no flags is present)

What about softlight? Seems to work on visual color...

[Selur]

Sure, any color filter can change the color, that is their purpose and that would fall under color grading,...

[Doom83]

Try the filter Levels, seem interesting..there are a guide how it work for best setting?

[Selur]

Not, that I'm ware off.
'Best' is usually highly subjective, so aside from additionally looking at the histogram also see the general change in the histogram, I don't think there is any advice.
