What do you mean by "Image" :?: Quote:
Still a no no :?: I use 112Kbps almost exclusively, leaving more bitrate for video Quote:
TMPGEnc shouldn't be set to "0" :!: At least that's not the default in my PLUS version :!: Quote:

If you don't want to use 'dual channel', please use at least 'stereo' instead of 'joint stereo'. The current MP2 encoders are not very good at joint stereo, you'll get glitches and distortion in the audio track very easily.

@Boulder, So I guess that joint stereo is a No no No :!: :lol: Thank you guys, I am encoding right now Friends Season 1, 3 episodes per CD with KVCDx3, with all this suggestions of yours. I did some LBR tests but I was dissapointed. My encodes were by far worse than Kwag's KVCD test disc with the Seinfeld scene. I was aiming at that... 6 episodes per CD, but I guess I did was not able to tweak it right. Regards, |

Thanks in advance :) |
Hi GetUp,
Motion Estimation produces better quality and less artifacts. At least on all the latest tests I've done with the current script and AviSynth 2.52. You can clearly see less artifacts around moving objects, and even though the CQ is slightly lower than with "High quality", the results are better :) -kwag |

You don't need to do tracks/chapter. Use ChapterXtractor to read your .IFO, and Cut&Paste the information into VCDEasy. It will create chapter entry points on your single MPEG file. -kwag |
Then that leaves us just with selectable subs and multiple audio tracks, which we rather not use anyway in KVCD :?:

Quote:
There are very few players that can handle selectable subs on SVCDs. So that only leaves selectable audio channels on a SVCD as an option :mrgreen: -kwag |
But you can still encode as a KVCD and after that mux as SVCD with 2 audio tracks! :wink:

is it the same for scripts without the dynamic filtering? |

Well, I did a small test and it looks like the motion estimate search produces better quality despite the fact that CQ has to be reduced slightly. I don't use the adaptive filtering because of the damn permanent subtitles in the TV broadcasts here :evil:

I've tested a lot and here I've a link to compare the CQ and CQ_VBR at a resolution of 352x(240)288 PAL.
TEST: CQ vs. CQ_VBR If the results aren't good for you download the pics and use the zoom function and you will see CQ is better in every resolution. |
Who ever did those tests, probably didn't consider many factors.
We've already proved here that CQ_VBR is better than CQ for resolutions of 352x240(288). That is, when comparing both CQ and CQ_VBR targets to be the same size. Those screeen shots don't mention the process, and there is not enough data. In this threads, we did provide all the data and procedures ;) -kwag |
I don't know clearly what you say, but I've tested a lot of resolutions with CQ and CQ_VBR and in my results you can see the difference. First I've tested a resolution of 480x576, but the artefacts in this Video with CQ_VBR were very high.
And then I've tested VCD resolution. And I don't know why but you can see that there are more blocks with CQ_VBR because this mode has too little weak in high action scenes. Can't you that the pics on the left side are very shaper than the right? |

That's clearly stated in this thread, that above 352x240(288), CQ is better than CQ_VBR. Quote:
Again, read this thread from top to bottom, and you'll see the FACTS :!: -kwag |
Quote:
So the choice as to be done according to the "actioness" of the movie. |
Quote:
They say another and there are more blocks at a resolution of 352x288 with CQ_VBR. CQ vs. CQ_VBR |

-kwag |
And I would add something : I do not use CQ_VBR for VCD resolution because someone (even if he was kwag) told me to do like this . I use it because I tested it and compared to CQ. And I trust the one and only tool I ever use : my eyes.
Do not follow foreign advices, test it by yourself and take the one you prefer. I use MPEG1 where others prefer MPEG2. I do not use the MA script when others say it rocks. I never encode the audio in dual chanel mode. And I use tmpgenc for muxing. You aren't a number, you are a free man :-). |

So we are still at the point we were in my first post : the choice must be done according to what is in the movie. And I agree with you that in the present case, CQ is better than CQ_VBR. |
Well CQ or CQ_VBR......
in these samples above I see a total horizontal distortion/frequency cutting! Thats the one which would make me think about it, the CQ or CQ_VBR is not the problem in these pics. It seems like a very overdone cutting using DCTFilter or the right colums of the DCT matrix. Inc. |
pfew.. another long thread.
Listen, I remember following this very long thread (when it was short, way back when SansGrip was adding his research knowledge etc to it) and even then, it was considered long. Anways.. I remember following it while at work (every day) and it was fun and very interesting indeed. This was the kind of thread/topic etc that I always looked forward to while at work. Anyways.. I think what was kwag was saying is that you need to first read through the whole thread (not just the tail end) because you miss so many key points, of which led many of those that did the painstaking research (and testers) a great deal of time and effert to conclude to. And, many of those key points were at the beginning and then some. There are many key factors that led one here, to there and so on and so forth. So, w/ the above in mind, all those sample pics that you see (afer reading) should be followed (to the letter) those settings used in TMPG (that includes the proper bitrate settings, and those w/in the scope of the CQ vs. CQ_VBR analysis) and the various Filters that were used during the testing (and debating) plus the various .AVS scripts that were used, and the source type (Resident Evel, for instance) (yes, like I said, I read it) and some ofthe tools used to compare the pics as well as the encodes etc :P .. .. .. getting some coffee .. .. .. -vhelp |
Sorry, I had technicle issues w/ my pc..
As I was saying.. I remember those that contributed, rendalunit, jorel, maudib, jellygoose, kwag el_mero_zooter, black prince, GFR and others.. the list goes on. Check page 8, for intance. And, notice the CQ vs. CQVBR pics. Did you use the same source files as those in the test threads here ? Did you use the same .AVS scripts; filters; settings; bitrates etc etc etc ? Again, all within the same params as those in the thread, and matching the same sources etc etc. Course, TMPG has evolved since that time, two years ago. So, the CQ/CQVBR mode may have improved. Which in actuallity, my cause your argument to become null'n void :P That's about it, -vhelp |
