No worries mate...we forgive you :D

In BBmpeg do we untick the "Align Sequence Headers Box" also?

ozjeff99

:) Nope. Must be like this:

http://www.digitalfaq.com/archives/i.../2002/12/5.jpg

Also, check "Pad VCD Audio". If not, it will then be done by VCDEasy. So you might as well sheck it too.


And BTW, grab CQM 1.03 http://www.kvcd.net/CQMatic-1.03Release.exe which avoids running the program more that once ;)

Holly Moses kwag:

You are diligently working on CQmatic. We all thank you for your eforts............For your knowledge in these matters and your style, you are a gentleman and a scholar :book:

I am changing versions as we speak. Do not know I am going to be able to complete 2 tests, but I am presently running one. On an earlier test, I received a CQ of 1.........But, right now is working fine, It is on in 2nd pass, if you include the fast pass as the first one. I will post the results as soon as they are completed.

Hi Kwag..

I forgot to post my results of some tests I did earlier this evening.
But, just so that you know, I TMPG crashed during the 4th pass I think, or
so. This time, it was encoding a lot more source frames :) from start to
finish. But, I ddn't like how long it took though :( Never the less, it's def.
an improvement on my end (given the history of my issues) I don't know
whta causes TMPG v2.56 to crash though. It was a clean install and all :roll:

Thanks for your assist,

Windows 98 :roll: :idea: That is a VERY low CQ :!:
What resolution are you encoding :?:
You are either encoding at a very high resolution, or you are encoding without filters :!:
The prediction time is really aweful on CQ values below 40, because of the non-linearity of CQ curve in TMPEG. There's no way around it :!:
The same applies for CQ values between 80 and 90. It's a real pig trying to find CQ. If CQ was linear, it would only take one iteration, and BANG!, CQ found, but this is not the case :(

-kwag

@ Kwag..

Ok, thank's for the above :)

After researching my faults, I found that:

1 - new version of tmpg, (see below)

2 - I was just feeding a source straight through w/ out any pre-filtering ie,
......resultion, cropping, aspect ration, etc etc.

3 - and no (not enough) tmpg configuring. GOP field is blank, and a few
......other things don't look the same from v2.53 settings :roll:

Well, I'm getting exhausted.., done way too much to much today, and lately,
I'm listening to my body tell me what's best for me :wink: And, it's telling
me ta get some shut-eye!! I find that I wake up w/ much more energy in
the morning :)

I'll see you all tomorrow,
Have a good sleep all :)

So you are drinking Guiness now :?: 8)

Tried Dumb & Dumber
PAL
Avg 947
Max/Min = 2000/539
100minutes

I know this is low CQ since its full screen but watchable at CQ 40.

After many iterations in prediction only mode CQM arrived at CQ 45.1 and kept repeating sample encodes at this same value in endless loop. The CQ is probably OK though.

Two questions:
1. How do you get copy of the Log. I can only select line by line and Ctrl C, Ctrl V does not seem to work. I'm using XP.
2. What Max/Min settings are best to put on 2CDs since the avg bitrate bumps up to 2023.

Thanks
ozjeff99

Actually, last night I had just one "Samuel Adams" beer :) Endless loop 8O, not on 1.0x release :!: Double click on the log window to copy to Clipboard, then "paste" to notepad MIN=300, MAX=2,500 :)

-kwag

endless loop
 

I am seeing the endless looping by cqmatic 1.03. The CQ came out to 69.23 and it never did the full encode...(this kept repeating thru the whole night :-))

Re: endless loop
 

8O 8O
I know what it is.
Something I had in 1.02, and I took it out on 1.03 for debugging :x :imstupid: :doh:
I'll fix that now, so keep an eye on this thread :!:

Tried CQMatic for the first time last night on a friends pc. Not sure what to make of it at the moment. Lots of people are having success with it, so I must be doing something wrong :(

We were wanting to put Spiderman on 2 CD's, with a running time of just over 1 hr 56 mins, that gave us an average bitrate of 1658, allowing for an audio bitrate of 192.

The movie was ripped, and we frameserved a sample of 2 mins from the middle of the movie with DVD2AVI.

Using the Optimal script, (just changing the GripCrop parameters to match the required template resolution), in TMPGEnc, I loaded my template (KVCDx3-MPEG-2-PAL.mcf) and set the min bitrate to 300 and the max bitrate to 2000.

I saved the project as a text project, loaded that into CQMatic along with the running time and avg bitrate, and ran a prediction. It didn't take long to run and gave me a CQ of 90! :D

What should I have done at this point?

What I did, was run CQMatic again, but this time in full encode mode and all I got was a CQ of 60 :o , which is what the template starts with anyway.

I then viewed the resulting video clip, and to my surprise it didn't look any better to the one I had encoded earlier directly from the template with no filtering.

With so many guys having great success with both using filters and CQMatic, it is obvious to me that I am doing something wrong, but I just don't know what!!

Can somebody please help?

@kwag,

Could you run through a basic step by step process, on how I use CQMatic to get the best CQ for encoding a small sample clip, so that I may view what the resulting video will look like before committing it to a long encode?

Thnx in advance.

Hi mistermickster,
You could start by changing the min.bitrate to 1658x0.57=946. Maybe that could give you a more correct file size :idea:

Hi mistermickster,

In the directory where you have installed CQMatic, there will always be a file named "X.Sample.m1v" where X is the name you gave as target in TMPEG. So if you were encoding "demo.m1v", you have a file "demo.Sample.m1v" left on your drive :)
You can play that in WinDVD or PowerDVD and see what it looks like, or better yet, open it in Vdub and look at the frames.

-kwag

1.05.00 up!
 

Grab it :!: At the top of this thread ;)

-kwag

Did somebody already mention a Batch Function ?

Is this guide going to be translated?

kwag:

This is just an update. I used CQmatic to predict another film, and this is the result:
No problems seeing here. I will encode the movie tonight and post the results tomorrow.

Thanks

Totonho03

CQMatic suspended until further notice :!:
Please don't waste time testing, as the current results are completely unpredictable on some movies. I'm re-designing the complete prediction algorithm, and until I get at least a ~2% final file size difference on every encode I test, I won't post another version. All versions on the site have been deleted.

Thanks,
-kwag

Kwag,
 

Sorry about that! I'll keep on using 1.05 until you release something else. I'm having great results using vhelp's vcalc to determine bitrate and cqmatic to predict CQ. Only one film overran and by only 12 seconds out of 99 minutes. The others have final muxed files within 2%.

I am making 2 disk KDVD 720x480's for miniDVD's. I use vcalc set at 1000, not 1024 and 1400 disk size. I set file size as 698 in BBMPEG to have room for chapters in TMPGEnc Author.

I've attached one log and avs used:

@ nicksteel,

Boy, I'm glad that "something" is working well in VCALC -- pfew!!

Oh, I finally figured out where I saw the 1000 vs. 1024 being used, and
why I added it as an option! vcdhelp's java calculator. Has the option,
but it doesn't quite explain each use - oh well.

http://www.dvdrhelp.com/calc.htm:
I just hate to leave out stuff, so, I incorporate as an option anyways :)
@ nick,
you might very well be the only person meeting w/ success w/ VCALC !!
(and still going through some more changes/revisions, as I write this)

Continued success to ya,
-vhelp

Vhelp, if you add more options, a preferences file would be most appreciated. For example, I always use 1024 and 1400. I'll let you know how usage works out in the future.

Hi nick,

Thanks, but please, can you suggest that in my thread instead, so not
to taint this one ??

Thanks,
-vhelp

hi nick..

I made a post in the vcalc thread, your question..

-kwag

Kwag could I ask what values you used for min/max bitrate during your testing? And which bitrate calculater you used? There seem to be so many possibilities now I'd like to know which you used to warrant this new release. Thanks!

Hi J-Wo,

I use MAX of 2,000 and MIN of (0.57 * Average).

-kwag

Thanks! Did you optain avg bitrate from MovieStacker or VCALC, and if the latter which settings?

Right now, I've been using average bitrate from Moviestacker. But you should be able to use any bitrate calculator that gives the same results (give or take a couple of kbits :) )

-kwag

Hi J-Wo..

I think Kwag uses MS in his projects (even tests) and most of his
calculations and things are based "off" of MS's. But, as you and others
here have demostrated, other calculators can (and do) work in a given
scenario.. thanks in part to the "variables" of one's projects ie, source,
source quality, users methods and filtering techniques etc etc and the list
goes on.

I'm speaking from my own personal view - - after reading Kwag's
many articles, its not hard to deduce what he uses in tools :) and 8)

Its all ---> C8)8)L

-vhelp

Hello Kwag:

This is the result of the latest CQmatic run.

I will now try TOK, do not know how long TOK will take..........

Regards

Totonho03

Here's my results for a 91 min movie, avg bitrate 1078 (from moviestacker). Script used was your MA from July 8, 528x480

Wanted file size: 728,194,990 bytes (from moviestacker)
Encoded file size: 749,221,556 bytes (2.89% over)

Vcalc reports an avg bitrate of 1008 (that's using 1024k and no MS precision), so I'll see in the morning if that gives me a more accurate file size.

Oh BTW kwag, I'm positively elated how much faster 1.1.0 is at prediction cycles!!! :lol:

Getting closer :cool:
Still not within my wanted ~2%, but close :twisted: Oh yes :D
It should now stay that way :cool:

-kwag

~ one hour to go.
Here's the prediction:
Kwag, sunrise is in about 2 hours in PR :!:

Yes, I should go to bed now :lol:
Ok, your movie is only 23 minutes long. Why such low average :?:
Are you encoding multiple segments on a single CD-R :?:

-kwag

Thats only a test source (you know already how problematic it is :D ). I'm encoding with such a low bitrate to get a good prediction and a CQ value near 60...
