This list is for people who know what it is, what it looks like and have decided that they don't like it and want to avoid discs having (a lot of) it.
Unfortunately I'm not aware of sources elsewhere on the net that tell us if there is DNR and/or EE etc. with any kind of accuracy and reliability, title by title. This list is supposed to be such a source.
First, I agree for the need for a list like this . . . . as it helps keep the studio's collective feet to the fire. If nobody complains then they'll keep
putting out mediocre discs . . . . they are not altruists.
Second, I agree with the majority of listings here.
I would like to inject one thought into the discourse;
SOMETIMES HALOS ARE JUST HALOS . . . .
. . . . which is to say, sometimes they are not an electronic issue
and thereby sometimes not a wholly accurate indicator of the quality of a transfer.
Halos occur optically in nature around boundary areas of high contrast.
Our eyes can add halos, camera lenses can add halos,
diffusion filters DEFINITELY add halos, bad films prints add halos,
bad telecines add halos . . . and OF COURSE electronic edge enhancement
and white level push can add halos.
The worst case scenario is a combination of the above . . . . EE makes it
all much worse but again, there are often other culprits as well.
DNR can make optical halos -- IE halos ON THE FILM -- worse by
removing edge sharpness that could make the halo less defined . .
. . . and keep in mind that in general compression does not like
edges or contrast and tends to add noise around them.
SOMETIMES HALOS ARE JUST HALOS . . . . not necessarily
an electronic problem.
Again, this is a really helpful list and I have used feedback like this to avoid buying certain discs . . . . I would add to please keep in mind the perspective that sometimes halos are naturally occurring optical phenomena . . . and sometimes halos are added for artistic intent . . . and sometimes
your eye adds halos.
These questions always want to asked AND ANSWERED by the studios but
SOMETIMES HALOS JUST AIN'T A PROBLEM. . . .
. . . so let's just watch the movie.
My veracity to comment comes from having worked in the camera department of one of the older films on this list. Alas, it is not as fabulous
a transfer as I would have wished . . . . but it does reasonably represent
the sense of the look of the film. The film used double fog filters thruout
-- a combo of a fog effect and a diffusion filter -- which definitely added
halos. The entire film was also post flashed which tends to add a bit of grain in the shadows.
Alas, another thing to keep in mind is that FILM IS FILM AND DIGITAL IS DIGITAL . . . . . and they don't always play well together.
I saw a 70 mm blowup of this film direct from the original 35 mm anamorphic negatives -- not from an IP -- and THAT my friends was
amazing. Yes, there were halos but they looked just great
