I want to know the answer to the following question:
What step of the DVD production process causes contrast banding?
All the background I'm provided with is that "As the LaserDisc format is not digitally encoded and does not make use of compression techniques, it is immune to video macroblocking (most visible as blockiness during high motion sequences) or contrast banding (subtle visible lines in gradient areas, such as out-of-focus backgrounds, skies, or light casts from spotlights) that can be caused by the MPEG-2 encoding process as video is prepared for DVD.". Is that enough to answer the question?
Answer: yes
