2 tests and results using CQMatic 1.0RC1 searching prediction:
first: wanted size 290mb,31 minutes. after 3 times searching prediction give CQ63,62. second: wanted size 800mb,88 minutes. after 3 times searching prediction give CQ64,14. i did 2 differents projects with dvd2avi. the first with 56409 frames, 31 minutes, the second with 159613 frames, 88 minutes. i think it's perfect cos the final final CQ for each have seamless and they are from the same source (dvd)! i did the same tests twice...same results :!: :wink: |
Just adding my results (first time with CQmatic)
1 test and using CQMatic 1.0RC1 searching prediction: Kangaroo Jack MA script 352x480 encode average bitrate=1106 film length=89 mins Min=300 Max=2500 Cq=64.75 Won't bore you with the rest - 799M result with audio(128K) :ole: Just a couple of questions: I was using Min=300 Max=2500 - should I have used Min=average bitrate*0.75 and Max=2500 .... it did seem on target using the default KVCD template Do I have to always find the target for TMPGenc before each try using CQmatic - or will it remember? I may try the movie using 480x480 resolution (DVD player won't plaly the 528x480 :? ) - though still not sure if a lower CQ (~54) value is worth the increase in resolution Anyway so far great work!!!!!!!! :angel: |
I think there is some confusion here. .75*min or .57*min??

Hello audi2honda:
Several posts have stated that the minimum should be (avg X .57) Totonho03 Edit.- Audi2honda: I went back and saw what you are talking about............ I will go back to some other posts and try to clarify, at least in my mind what the proper number is.... |
Yep, we need a clarification on this number.Different quotes regarding this issue:

Totonho Edit: This has been answered. It is (average * .57) Thanks kwag |
TESTING CQMATIC WITH MODIFIED MVCD2.5EX TEMPLATE
Yesterday I encoded "The Bonecollector" with an modified KVCD Template.
FACTS: The final file was to small. 783 MB inkl. 2 128 Stereo MP2 Tracks. Today now I test it with an modified MVCD 2.5ex Template. I did before a short sampler with both templates. Because I encode in 704x576 I was wondering why I get a better Quality with MVCD2.5ex!!! So I encode now the movie again. I will post the FACTS then. BTW: I had with KVCD a CQ of 53 and with MVCD i have now CQ 57.75!!!! What I changed in both Templates: Motion estimate Search, 704x576. CQ 50 for start. MVCD2.5ex encode 10% faster than KVCD... Why ???? Here the CQMatic Log: Quote:

704x576 is higher than 528x4576 :!: But the longer the movie or more action (after bitrate starts to exhaust), you'll get more bits per pixel at 528x576, and it will look better than 704x576. Quote:
The only way you can compare, is if you make a target file size "identical" with their's and our's, and then compare ( I did, and I know the results :mrgreen: ) BTW ( and FACT: ): MVCD and mole are " PERSONA NON GRATA" here, for their thieve practices. Maybe you should look at some facts here: http://www.kvcd.net/forum/viewtopic.php?t=4364 and here: http://www.kvcd.net/forum/viewtopic.php?t=4351 which of course, now they have their own matrix, but their foundation was based on our work, which permanently marks them as "Pirates" of technology. Quote:
Of course :!: The encoder is seeing less data (because of their matrix), so you're loosing frequencies that are being discarded, and are not being processed by the encoder :D Thanks for bringing this up ;) -kwag |
@Avalon,
Saying "mvcd" around here is similar to swearing! :lol: As Kwag directed you, mvcd blatently and disrespectfully ripped-off their ideas from KVCD and didn't admit it. They may have made a few extra changes here and there lately so that they seem different or unique, but most people here at kvcd.net know the real truth about mvcd's origins. -d&c |
After many tests i thought i would try an just do an encode and here are the results
Quote:
Current CQ = 80.874969(feeling pretty stupid now) but i decided to use 81.082985 and the final size of just the video is 792 m,now i figured i used the wrong one but there is such a small difference it wouldn't make it that much bigger. |
Hi bigggt,
Well, I think I'm going to have to specify that CQMatic is accurate only on DVD (MPEG-1 or MPEG-2) sources (for the time being), and not on avi sources :!: I'm getting very accurate results, but only processing .d2v (DVD) material. Maybe it's a CODEC related issue when reading the avi :idea: That's the ONLY thing I can think of, because it's the same process to calculate prediction, no matter what the source is. @All, Here are the tests I have encoded since yesterday, all with CQMatic RC2: Red Planet (352x480): CQ: 80.120 Encoded size: 742,198KB Wanted: 726,338KB :arrow: ( Diff. 2.13% ) The Bourne Identity (528x480): CQ 56.25 Encoded size: 715,574KB Wanted: 715,701KB :arrow: ( Diff. 0.017% ) K19 ( 528x480 - Raw, no filters. Only Bilinear resize): CQ: 61.06 Encoded size: 678,294KB Wanted: 699,875.78 ( Diff. -3.181 ) So for CQMatic RC-3, I'm adjusting the final precision by 1% (tighter) to shrink the final bracket calculation. This should bring the average final encoded material to about (-2% to +1%). -kwag |
Hey Kwag,the thing is Tok gave me almost the identical CQ and now when i went to mux the audio and video with bbmpeg(never had a problem before)it won't even scan the video so i'm thinking i must have a problem in tmpeg. here is what it says in bbmpeg

You bet you have a problem 8O. Look at this:
Code:
No. I Frames : 1 avg. size 13008 bytes Edit: Try this: Open your .avs file, and then load your template. Then save your text project :!: -kwag |
How would this have happened and how do i adjust it
|
Quote:
So just reload your template, but after you load your .avs source. Remember to clear the source range before saving. Try that :) -kwag |
Thanx Kwag,tried it with a short clip and everything worked ,everytim i open souce range i get errors so maybe i hit the wrong button :(
|
Here's another result, with RC-3:
Code:
http://www.kvcd.net Wanted file size (Moviestacker) 722,779.89KB Encoded file size 718,351.00KB -kwag |
Hi Kwag,
finally i have good results (1.0 Release) with my "problematic" source: Code:
http://www.kvcd.net |
Great to hear that Krassi :D
Well, I guess CQMatic is getting better :mrgreen: Btw, what type of source was that :?: -kwag |
