I think I know what you mean. It's the extremely high chroma values that are applied on very low movement scenes. I'm fixing that right now :) -kwag |
thanks for atention Kwag!
:D dredj a few minutes in his second post, see the same : http://www.kvcd.net/forum/viewtopic.php?t=4729 :!: |

I was able to see the effect CLEARLY on a specific scene on K-Pax. Here's the fix: Code:
ScriptClip("nf = YDifferenceToNext()"+chr(13)+ "nf > 2 ? \ There shouldn't be any "Bleeding" of chroma now. Period :!: I'm updating the script page right now. -kwag |
What now, are we in trouble again :?:
good thing i hanen't encode enything yet. :twisted: |
Don't worry, we nailed this one in less than 24 hours :lol:

:lol: really better(my opinion) :D and when i load the script in vdubmob it run soft, the system runs easy too and the image is cool without "breath" :!: the best...the prediction CQ encrease 3 points. :wink: @ Osvaldo, i did a encode when i see it and have to do all again. i have 9 8O movies to encode, my 2 hds are full of vobs.(100Gb) :lol: |
Hey Kwag TemporalCleaner sims to do a good job :!:
TemporalCleaner (ythresh=5, cthresh=10) Im becoming a filter frik now :mrgreen: |

everything is better! more CQ, more image quality, the system run soft and faster too. big goal Kwag :!: :D |
LOL

Just finished encoding K-Pax with the script update. I used ToK and "Fast" prediction, for a CQ of 64.18 Wanted video file size by MovieStacker: 714,303.19KB Encoded file size: 714,352KB :mrgreen: :mrgreen::mrgreen::mrgreen: I don't think we need to calculate the % precision this time :lol: -kwag |

Kwag,
see my results and if i'm using the right adjusts in ToK CQs predictions from ToK0052 with the new script! using 1st group of passes: precidion% 0,50 speed up by 1 time :arrow: CQ: 59,639 :wink: and using new faster prediction (Tenra) :arrow: CQ: 59,638 :wink: right? you only check the (Tenra) to got your results :?: :) |
Hi jorel,
Yes, I only check "New Faster Prediction", set Precision to 0.5% and Speed Up by 10. For full prediction, I uncheck the faster prediction, and also uncheck the 2nd group of passes. Then I change the first group speed Up to 1. For all, I leave the factor for prediction set to 1.0. -kwag |
thanks... :D
testing all ways now! :wink: |
Well what can I say :!:, here's a sample from the last encode :)
I think this just can't get any better ( at least for the next 48 hours :lol: ) This looks almost like ( or like? ) my DVD :mrgreen: www.kvcd.net/k-pax-fixed-adaptive.mpg Comments always welcome :cool: -kwag ;) |
Kwag
i download the k-pax sample and see good quality colors with great matizes, amazing sharpness too. right as you wrote "I think this just can't get any better ( at least for the next 48 hours :lol: )" :D for me too. |
8O
How is it possible that CQ goes up when you lower the filter values?? 8O |

Now that the picture is extremely clean, the CQ goes up :D -kwag |
Re: LOL

Kwag, are you using 1 sample per minute and the auto sample size for your prediction? |
Kwag,
Does the latest changes on the optimize script applicable or will work best only for a very clean material like DVD? Thanks, Dredj |

Man this stinks. A new movie just finished and was 7% short of target for 1CD. 50 wasted MB bah :evil:

hey audi, you're not the only one getting short video files! Kwag are you the only one getting accurate prediction? Sometimes my movies are only 90 min long so I usually do prediction with 2 samples per minute. In my latest encode:
Required Video Size: 732,032,000 Encoded Video Size: 693,986,212 That's 38 Mb short, or 5.2% off. Frankly I don't know what this means but a prediction factor of 1.0 for me is NOT doing the trick. |
@audi2honda,
You bet it can :!: You'll probably need to sample a wider "window" to get a better accurate result, and even that I'm not sure if it will be accurate enough. All my encodes have been progressive. I'm pretty sure that if your material was 100% telecined, and you use telecide and decimate, you'll still get accurate resulte. But mixed 8O :?: :!: :!: Not sure. -kwag |
Ok I'll try one of my progressive DVDs tonight when I get home.
J-Wo are you having problems on clean progressive material or just other material? My current project are DVD versions of a television series that have all sorts of hybrid nasty interlaced stuff in them. Telecide and decimate produce wonderful results, but I guess that could be throwing prediction. Kwag do you recommend more samples per minute or a longer sample size? or both? |

-kwag |
It's a randome mixture but after frameserving from AVS with the telecide and decimate functions isn't it all clean 23.976 when it gets to TMPGEnc? I would think in that case prediction would be accurate because TMPGEnc doesn't know since it's allready been converted or IVTC'd
|
Yes but because the film is not going to be smooth ( some parts will be smooth and some will be jumpy ) that will throw off any prediction for sure :!:

audi: yes, my sources are 100% film and all progressive. They are from clean DVD or SVCD sources. Kwag, any idea what is throwing off prediction for me? I almost want to revert back to before you got MA with full linearity

Hey guys, I was having some trouble with prediction too, my video files were also 30-40megs short or so. I think I've gotten around it by changing the # of frames per sample from 24 to 48, and the # of samples per minute from 1 to 2. I'm also following Kwag's advice and doing full prediction, which always seems to increase CQ by a liiiiiiiitle bit vs. fast prediction. But there it is.
|
Well, today I encoded the same movie (K19) twice, but after the first encode, I changed the prediction to full without exiting ToK. I did this on purpose to log the "fast" CQ and the "normal" CQ on the same log. Here's the complete log:
Code:
============================================================= With fast, CQ = 62.584 and file size = 676,918,065 Witn normal, CQ= 62.951 and file size = 696,413,210 Look at the difference in file size, 19,495,145KB but on CQ, it's only 0.367 :!: Again I got 0.964% ( less than 1% again! ) accuracy with the long prediction. That's why I'll wait the extra time for the longer prediction :idea: -kwag |

in Quality between 62.58% n 62.95% :?: i dont think so but it would be great to be closer to the target w fast prediction. :) |
