The biggest issue with the image quality is the yellow leaching that appears on flesh tones and elsewhere throughout the film. The same problem exists in the commercially available DVDs, waxy faces and all, so I can only assume the 35mm film negative has serious degradation issues. Then, when it was already damaged, it was used to make the VHS and DVD copies.

Here’s a still frame of the .VOB file I’m working with on Premiere Pro. The color damage is there but not as noticeable in my editing software:

Unfortunately, this is the output I get whenever I render, and it sadly resembles the source file I received, as well as the DVDs. Notice the yellow blotches all over the man’s face:

This problem persists throughout the entire movie, so I can only surmise that the original film source used to make the DVDs and VHS tapes was already damaged. Is there any way to correct this? The first image doesn’t look nearly as bad.
