Those clips despite being dirty and faded look wonderful. ... How are you compensating for the red shift?
You had it first right that this is "faded" but "red shift" is a misnomer here. The three colors that make up the film image haven't been shifted -- they are all still there, only not in their original strengths. The faded colors have been reduced in contrast, but not all at the same level, which gives the red effect. If we expand those individual color contrasts back to where they came from, the original picture is suddenly "restored" (as in this quick-fix comparison):
I go into more detail at "THX 1138 preservations (Italian Cut available, see 1st post)":
So this red print "may yet be of some use to us" ...
