Nothing stops you
Use CQMatic in "Prediction" only, and once you get your CQ, run TMPEG and add your audio and encode video/audio simultaneously. When TMPEG is done, you'll have your .mpg ready

Do I read right ? Kwag, you suggest to encode audio with TMPGenc ?
How much beers did you drink today ?

Dialhot,

I would be using tooLame for audio encoding, not TMPGEnc!

Unfortunately, I need to amend my settings and run another test as my DVD player will not play the resulting sample, it's displays all green. Is that a resolution issue?

I attempted to use Toolame some time ago within TMPGEnc. Final would play ok on computer, but no audio with DVD player. This was using TMPGEnc wizard for NTSC with 44.1 file from Headac3he to make compliant VCD.

Only if you use an external encoder ( like SCMPX, etc. )

Not as many as you did. Read original post

Tried a different resolution last night, 720x576 (I'm in PAL land), still got a good CQ and the picture looked excellent on my PC. But it still would not play on my Alba DVD119.

Maybe it just doesn't play non-compliant VCD's and I'll have to switch to MPEG-2.

I remember seeing a file to download which contained samples at all resolutions, but I can't remember where. Can somebody jog my memory please?

Thnx Kwag

I'll give it a try as soon as I get Nero

In the meantime, I've made a sample that successfully runs on my DVD player.

MPEG-1 at standard resolution 352x288, but with a bitrate of 1481 and a CQ of 89. Result's pretty good, still cannot see a difference between sample using MA script and the one that isn't though.

Starting to test MPEG-2 resolutions now to see which play and which don't.

I'll keep you all posted.

Hi, normally I would encode 2 episodes of a 45 minute show e.g. Smallville which I record from digital satellite into KVCD (352x576 resolution) (with 128 audio or 160 bitrate) and they fit on a single 80m CD. NB: I'm using PAL.

Now I've tried to use CQMATIC to encode an episode into KVCDx3 (544x576 MPEG-1 which works with my dvd player) instead but to give me the same size. I don't know if it was a silly idea but the result looked quite good except for some moving backgrounds in one scene. Basically I was trying to get a result which was better than the baseline KVCD - between KVCD and KVCDx3 and still fit.

The resulting CQ for the ep I did was about 56. I'll be trying again tonight, hopefully with another episode. The avisynth script is a custom one but I'm using Convolution3D (latest version) and the combination of stmedianfilter,mergechroma,mergeluma from Kwag's script. I also use DCTFilter(1,1,1,1,1,1,.5,0) - just a little.

Edit: I've realised that I was filtering too much. So I'll either do stmedianfilter or Conv3D from this point on..

hello, newbie here. i experienced the same with nininbert when encoding Finding Nemo. Second pass is totally black in tmpgenc's preview window. by the way, i have a silly question. why do you guys bother to use prediction with CQ when file-size can be perfectly predicted using tmpgenc's 2-pass VBR? is CQ better than 2-pass VBR? And why does KVCD uses 128kbps audio that is Dual Channel? Isn't Joint Stereo better for this bitrate? Here's something i learned from this website: http://www.modatic.net/audio/glossary.php#dualchannel

"Dual Channel -This is the same as stereo except that it fixes the bandwidth to each channel. eg. with a 128Kbit/s file, each channel will have exactly 64Kbit/s to allocate to various sound events. This is a really bad idea since you might have a song that is more active in the right channel, so it would require more bits, then there's the left channel that is really quiet but is still using 64Kbit/s and because the left channel is hogging bits it does not require, the right channel is not getting the bits it needs to sound reasonable. Do not under any circumstances use this mode unless you want the worst sounding mp3s!!!"
Thanks a lot.

welcome in forum onyx!

great observations!
a few days i post questions about this and have the same opinion.
i think that
"Dual Channel -This is the same as stereo except that it fixes the bandwidth to each channel. eg. with a 128Kbit/s file, each channel will have exactly 64Kbit/s to allocate to various sound events. "

please,take a read in this link and post some observation:

Yes It's really better than the 2-pass VBR. I've run several tests to verifiy this. And encoding time is shorter. There's a thread where CQ and VBR is compared, can't find it at the moment. I think it's called CQ vs. CQ_VBR or something like that.

i'm sorry about my last post. tmpgenc doesn't show black window in 2nd prediction like i previously said. what really happens is tmpgenc encodes 144,649 frames (which is the size of the whole film!) yet it only shows pictures (sample frames) for the first 2 minutes and after that the rest of the frames are blank. why is this happening?it happens from the 1st prediction and later.i am using the latest version of tmpgenc and followed all the rules on the first post in this thread.

this problem would have been posted before but i don't have patience to read all 32 pages of this thread.

thanks a lot

Hi,you need to erase the audio field in tmpge before you save your tpr file.

Kwag maybe we should post this somewhere like in the begginning of the thread or something

Hi bigggt,

I just updated CQMatic to version 1.2.01, which automatically erases the audio source field, and ensures proper operation
So no matter what you enter in the audio source field, it will always be cleared before starting the encode/prediction cycle.
This takes care of TMPGEnc bug.
Grab it at the top of this thread

i figured what causes the problem. it's the Inverse Telecine option of TMPGEnc. You see, i never use Forced Film in DVD2AVI even if it says 99% FILM. I always do manual IVTC. With IVTC disabled, the prediction works fine. But when it is enabled, CQMatic encodes the whole movie, with samples for the first 2 min and blank frames for the rest of the movie.

kwag, how am i gonna fix this? is it ok if i run prediction only with IVTC disabled and then place the CQ predicted in TMPGEnc manually and enable IVTC again? Won't the interlaced frames of a telecined movie mess up the CQ prediction?

by the way, you said it is important to disable "Detect Scene Change" in TMPGEnc when predicting CQ. But after i predicted the CQ and i encode in TMPGEnc manually, would enabling "Detect Scene Change" again give better results?

i am bothering you with questions. i'm sorry. but any help would be greatly appreciated.

NO. Use Telecide and Decimate in a script.

That's why you must use the script. Don't use TMPEG's internal IVTC. It's not good

That was a LONG time ago. Go ahead and turn it on

In the download post for CQMatic, the instructions still say to uncheck "Detect Screen Change".
