CQ:80 Bitrate: 2300 On dark scenes i could see blockiness...is there a way to get rid of them? |

Kwag,
I've read this suggestion on other forums, also. Could you explain what this does and why it would solve 'blocky blacks' problems? By the way, I think you must be one of the most patient people I've ever encountered. I hope hosting this forum doesn't burn you out. Thanks for all your help, past and present. |

Movies are encoded as CCIR601. So if we re-encode a movie, you can just output it as YCbCr, and not as CCIR601. So that it doesn't re-encode again as CCIR601. You wouold loose quality, color balances, etc. Take a look at the real technical explanation here: 8O http://www.crs4.it/~luigi/MPEG/ccir601.html kwag |

Update
Will someone PLEASE try this! I just encoded a 10 second clip of "The Matrix" lobby scene with TMPEG 2.55. With the standard VCD template, you can see blocks. If I turn on "Soften Blocks" and set it to 50/50, I see more blocks. If I set to 100/100, even worse. But if I set to 0/0 THERE ARE ALMOST NO BLOCKS 8O . It seems that the internal "Soften Blocks" works the opposite as described in TMPEG. Need feedback, and if I'm correct, I'll post this at Pegasys-inc's site as a question regarding the correct use of this. kwag |
