Sure, but one doesn't always have a choice. Especially if compressing a difficult-to-compress movie down to a DVD5. You can filter in the script, in the encoder (low-pass filter) or in the matrix used. mikenadia was asking about something similar earlier in the discussion. Me, I prefer to do it in the matrix and consider it the least of the three 'evils'. By using a 'better quality' matrix you might open the door to all kinds of artifacts and poorer results, in my opinion.

I didn't phrase that right. Sometimes they're not only supplied the masters but some ready-for-DVD encode. I presume, because the encoding settings are so peculiar and so different from the usual Criterion practices. That's what I should have said when I mentioned they're easy to spot.
