| http://www.divx.com/divx/ was released last night, but I'm hesitant to upgrade, since I read a post on Doom9 saying that there is no more "1-pass quality based" encoding mode (my favorite). Is it true? EDIT: Nevermind, it's still there.

| It seems to be missing until you disable the settings "Choose your profile". |

| It keep crashing whenever I went to 1 pass - quantizer. I finally had to use regedit to delete the settings key for DivX 5. I wonder what the nth pass does? maybe you can do 5 passes  |

Some guy at Doom9 has already tested 5 and 10 passes!  |

It takes long enough for 2-passes.  I use the 1-pass and spend more time filtering noise and such. |

Why not do your filtering and such, and store the result as Huffyuv? Then use the pre-filtered Huffyuv version to do your "n" passes. Much faster this way I would think, especially for n > 2 passes. Hope you have a lot of HD space! |

| I did some testing with the muti-pass encoding. I created a 640x480 23.976fps 22min YUV2 Huffyuv 9GB segmented avi file. With filtering the Huffyuv avi took 6 Hours. My target bitrate was 800kbits I enabled B-frames and set Psychovisual Enhancements to Strong Pass 1: 1:00 n/a Pass 2: 0:58 147,322KB Pass 3: 0:58 147,292KB Pass 4: 0:58 147,290KB 1 Pass: 0:58 147,026KB Quantizer 5: 0:57 181,484KB The best IMOHO was the one pass Quantizer 5. |

| I'm impressed with the codec, but I'm not planning on using more than two passes. It still seems a little "soft" to me and doesn't encode high detail (perhaps it's filtered out as "noise"), but considering the low bitrates I'm using it's still pretty damn good. |

No, sir... I din't like it at all! I didn't like the the little DivX logo they put at our videos. Is there any way to stop it doing that?  |
| Posted by: Cerberus Feb 2 2003, 12:53 AM |
lol DIV X logo... look in the settings you can turn that off....... its in the decoder settings......  |

Well, I finally did upgrade to 5.0.3 and I've done some of my own nth pass testing, but IMHO no amount of passes can beat "1-pass quality based" with a carefully chosen quantizer. (Don't let Neo Neko in here; he'll argue me to death about this!) |

| Update: Finally I downgraded back to 5.0.2 after deciding that 5.0.3 is too buggy and offers little or no improvements over the previous version. I have a few other gripes to add: - VirtualDub can't append a DivX 5.0.2 avi and a DivX 5.0.3 avi. - The DivX 5.0.2 decoder won't decode DivX 5.0.3 content. I don't get it. If DivX video is MPEG-4 compliant, then why are the old and the new streams incompatible? OTOH, if DivX isn't 100% MPEG-4 compliant, then why am I wasting my time with it?  becoming quite disillusioned... |

| ...even worse: - 1-pass quality mode is ot considered in any of the standard profiles. I use 1-pass quality based all the time and now I do not have any assurance at all that a portable DivX is able to play it... I am also getting a small audio gap while capturing to DivX 5.0.3 |
