If you add the transfer characteristics/color primaries/colormatrix (to bt709) you also need (or, it's better) to add also the videoformat 'ntsc' if you're encoding at 30/60/23.98/24 fps. The pro-encoders do this (you can not add the information, but if you add them also the NTSC video format is specified). I haven't tested it, but probably for 25/50 fps the 'pal' video format is added.

yes will work for all scenario ... and GOP 48 vs GOP 24 produce ~2% better compression efficiency.

Just leave default x264 setting. From revision r1537 x264 automaticly calculate min-keyint with keyint/10. so with Shot GOP min-keyint will be 2 with long 4, wich is just fine.
btw i am currently work to complete this stuff, be patient few more days with all need explanations |

Much appreciated, Kieran, good to know my tests have been BD compliant.
Can you advise me (and others) here - are the following encode settings also good? 16:9 "NTSC" 720x480 Secondary Video stream I know the max bit rate here is quite conservative, that is my intention. Code:
x264 --bitrate 3000 --pass 1 --preset veryslow --weightp 0 --bframes 3 --me umh --merange 24 --partitions all --subme 10 --trellis 2 --rc-lookahead 60 --direct auto --ref 6 --nal-hrd vbr --vbv-maxrate 4000 --vbv-bufsize 6000 --level 3.2 --keyint 24 --b-pyramid strict --slices 1 --aud --colorprim "smpte170m" --transfer "smpte170m" --colormatrix "smpte170m" --sar 40:33 infile.avs -o outfile.avc x264 --bitrate 3000 --pass 2 --preset veryslow --weightp 0 --bframes 3 --me umh --merange 24 --partitions all --subme 10 --trellis 2 --rc-lookahead 60 --direct auto --ref 6 --nal-hrd vbr --vbv-maxrate 4000 --vbv-bufsize 6000 --level 3.2 --keyint 24 --b-pyramid strict --slices 1 --aud --colorprim "smpte170m" --transfer "smpte170m" --colormatrix "smpte170m" --sar 40:33 infile.avs -o outfile.avc I gather that since 23.976fps is not allowed for SD material on BD, we need to add some sort of 3:2 pulldown flag. Is the way X264 does this BD compliant? |

EDIT: i create my own 23.976p sample, encoded using fake interlaced and puldown 32 to produce 29.97i stream, but this file will not pass mui generator. Last edited by shon3i; 11th June 2010 at 08:31. |
