OK here are the images again; this first is using VAQ:
The next one is w/AQ unchecked; it looks washed-out. Sorry for getting this wrong the first time! I will report again later after I've had a chance to look at these on my media player/10' wide screen! |

That's because you opened both at once in two separate media players, but since only one could use the overlay renderer, the other didn't get the proper TV->PC brightness level conversions.
It has absolutely nothing to do with Xvid or AQ. |

Oh my; that would never have occurred to me. I haven't looked at the vids outside of Media Player Classic yet, but I have no doubt you are correct about this, because indeed, in order to make certain I selected the same frame for comparison/screenshot, I opened two incidences of MPC!
Sorry for the bandwidth! :veryembarrassed: I guess at least I can take some solace re: how my original post was "wrong"--I simply opened in a different sequence each time. Last edited by laserfan; 24th February 2008 at 04:57. |

I feel stupid, because I cannot see any changes neither in file sizes or quality.
Because I've never grasped concept of some people's ON and OFF, be so kind and tell me what "check off" in your sentence means. Marked box or not? You know... is it yes... or not... UN-checked or checked as un-marked and - marked. Later, for sure. Thanks in advance. Last edited by 20-40; 27th February 2008 at 11:29. |

For VfW: Enable “Adaptive Quantization”
For Encraw: Add -lumimasking to CLI

So... in this case OFF means ON - as YES, as "marked", as checked.
Thanks brother, it's nice to see that off means yes. OK, "radio" box of “Adaptive Quantization” stays enabled, as always. Encraw will chew later on.

already heard that saying... it's religion related...
however, i think VAQ can be more effective with quantization matrices like 6of9 and similar purpouse matrices...

Maybe it is, Sharky, I've added this saying as absolutely relevant to my previous post - namely - and if you can pass personal "connotations" in it - it IS about UNDERSTANDING and PERCEPTION, two most valid things in this matter.
Next time, look without filtering, it was uncalled for, sayings as this one have been part of our civilization log before we were born. So respected man and Doom's forum member, as you are, don't need someone as me to tell you that. |

The only possible way of improving VAQ, at least IMHO, would be to implement a sort of rough detection of text, so advanced subtitles could look better. Probably some weighting that if the possible text is near the bottom of the video, it is more likely to be text.
To me, especially with stylized anime subtitles, clean subs are very important. Minor, and will most likely be shot down, but I'll throw it out there just in case. |

Of course, if you want clean subs, just use softsubs, seriously |

Point three in particular, since 4MV is on by default for basically all the profiles. Which takes precedence? Is a block coded with MODE_INTER4V precluded from dquant? Or does dquant force interv4 off? I scanned through the code looking for both elements 'together', and find stuff like: encoder.c/MBSetDquant Code:
if (next->mode != MODE_INTER4V && next->mode != MODE_NOT_CODED) /* mode allows dquant change in the future */ if (abs(next->quant - prev->quant) <= 2) { /* quant change is not out of range */ estimation_rd_based.c/xvid_me_ModeDecision_RD Code:
int inter4v = (VopFlags & XVID_VOP_INTER4V) && (pMB->dquant == 0); |

Awesome! As for the softsubs comment, pretty much the only reason I use Xvid nowadays is for hardware players... and those tend not to have soft-sub support. When I do make backups of stuff for PC viewing, it's x264 MKV with ASS softsubs
