The DV-to-DVD-HOWTO in the transcode docs uses these flags for mpeg2enc:
F 8, -c -q 6 -4 2 -2 1 -K file=matrix.txt -R 2
where matrix.txt is:
# Steven Schultz's combined HQ matrix cat - > matrix.txt << MATRIX # High resolution INTRA table 8,16,18,20,24,25,26,30 16,16,20,23,25,26,30,30 18,20,22,24,26,28,29,31 20,21,23,24,26,28,31,31 21,23,24,25,28,30,30,33 23,24,25,28,30,30,33,36 24,25,26,29,29,31,34,38 25,26,28,29,31,34,38,42 # TMPEGEnc NON-INTRA table 16,17,18,19,20,21,22,23 17,18,19,20,21,22,23,24 18,19,20,21,22,23,24,25 19,20,21,22,23,24,26,27 20,21,22,23,25,26,27,28 21,22,23,24,26,27,28,30 22,23,24,26,27,28,30,31 23,24,25,27,28,30,31,33 MATRIX
How does this compare with the mpeg2enc F 8 defaults?
does Steve Schultz actually use this? Faster? Better quality?
Is there anyplace that describes the matrix?
