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

Nope. Must be like this:



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

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

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

Thanks for your assist,

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..

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

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 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

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

Endless loop , not on 1.0x release

Double click on the log window to copy to Clipboard, then "paste" to notepad

MIN=300, MAX=2,500

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 )

I know what it is.
Something I had in 1.02, and I took it out on 1.03 for debugging
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!

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 , 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

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.
