Would there ever be the possibility of seeing a tutorial (or at least a link or two to a good tutorial on cleaning and/or color correcting)?  I would love to take a shot at the new SUSPIRIA blu-ray, among a few other titles.

Such as this scene right here:

 

 

 i can't see this image.. i went to the site,

all the images looked good to me.

 

if you need to ask for coloring advice, the

technical forum would be better for that.

it's a whole art into itself. i don't know

much about it.

 

there are filters for freeware avisynth/virtualdub,

for fixing scratches, cleaning up dirt, and dust. 

however professional software uses a lot more sophisticated

algorithms, including blending, color look ahead, temporal fixing

and others..

 

basically, it's a lot of looking back/forward at previous frames.

taking the pixels you want replaced.. averaging them over

time.. and pasting them over the original..

 

you have to look for non-damaged frames if the error is one

spot (lines/scratches).. in that case, you have to make an

educated guess at what the pixel color will be based on

the surrounding pixels and what there color is..

 

in still pictures with little movement like this, it works

great, because you have a lot more frames to get

pixel replacements from..

 

when you have short scenes, or a lot of movement.

then you have to go in by hand, and figure it out

by yourself.. otherwise most of its automated.

 

later
