hi totonho03,

Sorry, I lost my connect (sys crash) :!:

Quote:

Thanks for your answer. I tried downloading your sampler, but for some reason my computer thinks that this is an mpeg file, and I was not able to downloaded as a RAR file. I will try again later on today.
Be sure to Right-Click (not left) ...

and when the SaveAs box comes up, just give it an .rar extention in place
of the .mpeg one. For the life of me, I don't know why it comes up that way
though. But, I speculate, that it as something to do w/ the archieve being
an .m2v file (inside)

Just rename .mpeg to an .rar and you will be fine.

Here are my results w/ CQM v1.1.07 thus far:


I just got finished w/ TWO "predicts" w/ v1.1.07 and I was amazed at how
much faster it was w/ a complete "predict" of:

* Project type: MPEG-2 w/ 16:9 output for true widescreen viewing
* Movie: "Dogma"
* Length: 128 min - - - (used no seconds here)
* bitrate: 741 - - - - - - (based off, Form: Bearson calc mode, in vcalc)
* MIN: 423
* Last CQ: 49.152
* FileSize: 11.122mb

And, remember, "predict" was run TWICE, cause I coudln't believe it, and
thought that either my system would crash on the 2nd test, or give me a
complete set of different numbers. But, it game me the SAME :!:

Deffinate improvements !! 8) !!

see both LOG's 1 and 2 results below.

Same setup as before.. oh, and I think I have the perfect setup for getting
the "predict" testing to start the first time w/out issues :confused: finally..
and I wrote the steps down this time.. will test it out again, for the umpteenth

That's great :D , but use 1.1.08a, because I've seen file size differences from x.15 to x.20 CQ values 8O
So it's better to play it safer on precision :cool:

Ok, results are in:

No change. All is a-ok STILL !!

Mind you, these are results based off a "prediction" not a full encode.
I'm not yet ready for that. That will prove for sure, weather CQM STANDS
up, or sits down hehe to my expectatioins. I'm thinking of setting it up on
my 2nd pc and let it necode "Dogma" complete, for this test, but I fear that
my 2nd pc will not perform the same or give poor results based off of some
strangeness of my 2nd pc. But, that's me going :confused:

I'll think about it. Anyways, here are my "prediction" for same material:

Everything stays the same here, as before, again.

* Project type: MPEG-2 w/ 16:9 output for true widescreen viewing
* Movie: "Dogma"
* Length: 128 min - - - (used no seconds here)
* bitrate: 741 - - - - - - (based off, Form: Bearson calc mode, in vcalc)
* MIN: 423
* Last CQ: 49.15 - - - - - (from prev. CQ 49.2, and 49.152)
* FileSize: 11.122 - - - - -(prev. 11.123mb and 11.122mb)

:!: Note, I used vcalc for all my calcs above, w/ their respective settings.

Just a thought for your next version Kwag.. when you run the program and just click cancel straight out it asks you if you want to abort the process when no process is running.. Perhaps this cancel button could be disabled for when no process is running. Just a thought.

Thanks.

* Project type: MPEG-2 w/ 16:9 output for true widescreen viewing
* Movie: "Red Planet"
* Audio: 112 kbits

* bitrate: 909 - - - - - - (based off, Form: Bearson calc mode, in vcalc)

Note, imo, anytime CQ is 50 or greater, expect decent quality or better.
2 minute sample looked good in my opinion for a 1 CDR project !!

Well, I'm still "predicting" the Full 136min for "Matrix" ... and it's sucking
bigtime (the movie, that is) It's on it's 10th pass, wow. And, CQ seems to be decrementing by sigle digits like a count down timer . That just suck for me ("matrix" that is) cause I'm waiting and waiting ta go ta bed, and it's STILL going at it.. now down to CQ 23.21. But, I don't get it this time.
"Dogma" is a 128min and it only took 2 passes and CQ'ed at 51 !!

@vhelp,

Don't try to put a movie like "The Matrix" at 704x480 on one CD.
I did mention earlier that the CQ curve below ~50 will take a long time to predict, because of TMPEG. Not because of CQMatic :!:
Either lower your resolution to 528x480 ( Will look way better than 704x480 anyway :!: ) or put it on 2 CDs, if you insist on that resolution :roll:

Hay Kwag,

sorry, I was just trying to see if it would prove just as well, as "Dogma"
did, but it didn't.

It finally stopped at 173.95minutes after 26 passes. pfew!!

I was hopping "Matrix" would work, but I was dissapointed at "Matrix" for
now - (not at CQM) :)

Anyways, there are other movies to test (later on) getting ready for work :)

Have a great day all,

Gentlemen:
A FIRST ONE FOR ME!!!!! I finally completed my first kvcd!!!!!!!!!! :yippie:
I know, I know, most of you are way ahead of me but watch out, The Peruvian is running faster than un burro veloz, ja. Burros are notorious for being slow, a few will gallop, but most all of them just walk, they can carry a heavy load, but........
Anyway, the kvcd was not perfect. (Operator error) The size of the file was 799.692 MB, the audio is out of sync, but the video is great!!!!!!, and I was not using any filters at all!!!!!!!!!!!. And of course the only machine that played it was the Cyberhome 60 dollars player.

Now I have to do a lot of reading in order for me to be able to have synchronized audio, subtittles and a second languaje. Oh well, this is certainly not a boring hobbie.

Well, what can I say but to thank kwag, jorel, vhelp, black prince, red-m, vmesquita, new_bee, dialhot and many others that posted questions similar to the ones I had, as well as the folks who out of the goodness of their hearts took the time to write their guides, vmesquita, black prince, red m, Avalon, and the Spanish guides. To all of you: :drink: in your name with a big THANK YOU, ans a special :ole: to EL MAESTRO KWAG!!!!!!!

P.S.- Please do not get mad at you if I keep on posting what may seem silly questions to you...... :D

FWIW..
one word, color-space. eliminate the steps in between, that causes the
issues with, and you have as good as quality you'll get. Course, theres a
few tip'n techneque one keeps to him/her self :wink:

Listen, I'm glad you made it, pal :lol:

I've ben working w/ the "Matrix" predition, and have had nothing but poor
results, which I believe to be the source itself. I have a few hunches, but
I need the time to debug them ( which I'm doing now, sort of :) )

Keep up the good work.

Sorry mi amigo, I did not understand your meaning of the quote.

I was going to buy the Matrix and The Red Planet today, but run into virus issues in my computer and expended most of the day correcting it. I ewill more than likely do that tomorrow.

Best regards

vhelp 08-11-2003 09:01 PM

hi toots,

Sorry for the confusion :oops:
I was on a role. Anyways, fwiw, there are many factors that taint the color
space to a degree. In my experience, and imo, I feel that the more one
uses filters (filter items) the more of a chance you ARE tainting your sources
color space. But, depends on a number of factors. ie, how many filter
items you have in your script, ie, ConvertToYUV and ConvertToYV12 etc
as examples. Just using them once (IMO) is enough to make me wonder. But, as long as you don't notice anything, then it's safe to not worry about it :)

yeah, get the Matrix and Red Planet I can watch the Matrix many times,
and still enjoy it. IMO, it's an original piece. I just hope that the Sequal hasn't
spoiled it.
The Red Planet is another great movie.. worthy of a Sequal too.

Hello:

I have read many posts referencing audio sync problems, and I just came to the conclusion that the problem seeing by my player, may be due to a step I did not take, when using head3ac, meaning that I encoded the audio file at 48 k, and not at 44k, and it is clear that the player does not like it:
* Video lagging audio by a 2 or 3 seconds
* blips clicks and other type of noises heard on the player

However, the sound is very clean, read no clicks, and there is no delay at all when playing the cd in the laptop....... Does that make sense at all? Will this create such a long sync problem?.
Neither the Cd, nor the actual files have the audio sync peoblem when played by Power dvd..... :?

Thanks

I'm no audio expert, but I think that the only time where there is audio
sync issues is when there is a conversion going from:
* 48 downto 44 or
* 44 up to 48

but that if you convert your audio (like AC3 to 112kbits) from:
* 48k to 48k (like AC3's 384k downto 112kbits)

that there is no audio sync. I think thats how everything works thus far,
but I could be wrong. It's usually when you change the 48k downto 44k
or 44k upto 48K that things get screwy.

Perhaps if you used another MUXer converter like Lame or BeSweet, for
the Sample conversion, see if this cures your audio sync issues :idea:
Maybe :)

Yes it will :!:
An that's exacty the problem. You must downsample the audio to 44.1Khz in HeadAC3he. Not every DVD player likes 48Khz audio on VCDs ;)

totonho03 08-11-2003 11:32 PM

Thanks a lot kwag:
I guess that the Cyberhome does not like 48kz at all. I will try 44.1 kz tomorrow. Thank you for your response vhelp. Now I am going to sleep a bit earlier.
I also need to run defrag in my computer, and that takes a long time.........
Good night y'all

Hi!
I just wanted to thank you kwag for your EXCELLENT CQMatic! Last night I encoded "Daredevil". After 7 tries CQMatic gave me a CQ value of 62.6621. This morning I muxed the video and audio and ended up with a final size of 796MB. Perfect! :D That's just a 0.5% difference from the wanted 800MB. Thanks again!

totonho03 08-12-2003 02:15 PM

Hi:
I have redone the audio with headac3he at 43.1 kz but the audio sync issue is still present.. The video lags about 4 sec from the audio.
These are my steps:
1.- dvd decrypter, Disney cartoon movie
2.- dvd2avi, choosing the main film vobs, deleting the menu vob. Used Force Film
3.- Run headac3he, to obtain an mp2 file at 44.1Kz
4.- Encoded d2v file directly from dvd2avi. Avs script was not used.
5.- Mux the video from Tmpgenc with the audio from headac3he using BBmpg. VCD settings, as per Red-m's guide
6.- Checked the bbmpg mpg output with Power dvd, no problems
7.- Checked the cd with PowerDVD, no problem.
7.- Checked the cd at the Cyberhome unit, and both cds, one with 48Khz and the other with 41.1 khz audio, show video lagging audio by as much as 4 seconds

Any suggestions on how to do this, the correct way, will be appreciated.

Thanks

Hello kwag:

I have the Cyberhome ch dvd 300. I used 528 X 480 res. One thing that I did not do, was to check this player with the cd test, I took it for granted that this resolution would play ok. ....The video looks good...........and the file size went down a bit when encoding the audio at 44.1 khz.
I have backed up this dvd with dvd2one, with no sync problems at all....


Thanks and regards

I use KDVD with my Cyberhome500 due to motion problems with other resolutions. The player will play miniDVD without any problems.

totonho03 08-12-2003 05:21 PM

Thank you for your response nicksteel.
I am trying to work myself to minidvds. But first I like to be able to do back up using the kvcd method.just recently, like a couple of days ago, was able to burn the kvcd in question. Good video, but the audio is out of sync. My next project is going to be kdvd, using vmesquita method and cce......but I better hurry because the CCE 2.66 trial ends in 28 days...

Hi Totonho03,

I have that same DVD player, and my KVCDs play fine at 528x480 :!:
No video/audio sync issues.
Could it be your firmware rev :idea:
I don't know if the Cyberhome's firmware can be updated :roll:
I did have a problem with the first unit we bought. Every DVD we played, would freeze a couple of times in the movie. This happened with KVCDs and DVDs. I took it back to Radio Shack, and changed it for another unit (same model)
No more problems :!: I had a faulty unit :cool:

-kwag

totonho03 08-12-2003 06:14 PM

Thanks kwag.

My unit plays dvds with no problems at all. It even play some vcds that I purchased in Manila, with no problems. What I could do is to play the cd test and check it that way. I suppose that I can always exchange it, but the basic question remains: Am I doing something wrong? Are the steps that I am taken correct?
I am going to experiment once again with a different movie and will post the results. (Short clips at deifferent resolutions)

Regards

Totonho03

P.S.- I will also check to see if there is a firmware rev somewhere......

kwag 08-12-2003 06:45 PM

Hi totonho,

Your steps are correct. Coult it be the CD-R brand you are using :?:

-kwag

totonho03 08-12-2003 07:37 PM

Thanks kwag:
I am using TDK CD-Rs, I will use a Sony CD next, but before I will run some other tests........If I find the same problem, I will exchange the unit.......

Regards

Totonho

Perhaps I will venture into the minidvd arena, but like someone said someplace here, not very many players accept such format...Oh well, as I
ask before WHY ME?.... It looks like everytime I attempt something it goes wrong........I will not quit, will keep on trying.....

totonho03 08-12-2003 10:25 PM

Update:

I just finished testing about 5 minutes of "tears ", this time I used dvd2av2 1.77.3 and the result is as follow:

1.- The audio was a bit out of sync, with some cracling noises ,using 48khz
2.- The audio was perfect with 44.1 khz. Towards the end of the clip I saw heavy pixelation, but this pixelation was also present when I run the cd in the laptop, therefore, the problem was not in the receiver. :D
It appears that the audio sync problem, in my case, was traced to dvd2avi v 1.76. I will confirm this some other time. What I need to do is test the Disney movie with v 1.773, as well as some other clips...........

Thank you for the help

Totonho03

totonho03 08-13-2003 12:17 AM

Last report of this a.m.
Tarea cumplida, work performed.....I no longer have the audio sync problem. I went back to the Disney movie, and used dvd2avi 1.77.3, changed the audio to 44.1 khz, and no more video delays in the clip. :D
I am going to sleep now.

Thank you all

Hi Kwag..

All of the sudden, a :lightbulb: lit up over my shoulders while I was just
starting out my CQM v1.1.12a testing :) (now on 5th pass) and I for some
reason, I only JUST GOT THE CONNECTION I don't know :screwy: w/ the
2 plus 2 scenario of Aug 11'th "Matrix" testing dissaster.

Get on with it..

Yes, found out why it was giving me really bad problems. Turns out that
my dvd2avi was screwed up. Yeah. somewhere's in the begin to mid,
and randomely in other areas, "scenes would repeat itself" like as if I had
press the "repeat" button for a given scene. Like 1 second repets. And
this would go on through the movie. I'm realy sorry for the screwup and
causing you any bad taints during that days testing. Yes, it was really bad.

So, how did I find this all out ??

It was in one of my PDVD playing, that I coutht it. The scenes in the sample
that CQM made had shown me those "repeats".

So, I don't know what could have cause the faullup w/ the "Matirx" dvd2avi
.d2v file, but that was where I traced it. And, when I broght the .d2v file
back into dvd2avi, it was actaully showing me the screwup.

So, there have it. How it all begain. One suggestion to how it may have
came about is HOW LONG it took to dvd2avi to a .d2v file. In fact, come
to think of it, "Red Planet" was the same thing. It took an hour+ to complete
the .d2v file. I remember these two being SOOO LONG. Anyways, now we
know what the cause was. Can you deduce what CQM was doing, (and
having the hard time "prediting" things) with the "Matrix" now ???

So, what do you think.. that I'll get a better "Matrix" predict, if I try it out
again ??
I'm only afraid that I'll have the same problems w/ "Matrix" screwing up on
me in the .d2v file. If I can only know in advance if it's gonna hapen again,
w/out going through the whole process.

Well, maybe others here have had similar issues, but NEVER knew it, and
that my bringing it out into the open, it might help others too, in is situation.

I don't know about you, but this was great news to me, when I found this out
today (just now) !!

It means, I have a second chance w/ "Matrix" hehe..

:hopline:

Oh, and sorry for the LONG post here :)
And, thanks for listening :) :)

totonho03 08-16-2003 05:37 PM

Which version dvd2avi were you using? And how did you resolved it?

vhelp 08-16-2003 07:03 PM

@ Kwag..

I just finished my First testing of your lastest CQM v1.1.12a on my DVD
title "Blue Streak" - - great movie. Anyways..

I was a little annoyed at first, but then reasoned that this is CQM's operation and is normal :)
..that it crawls on those last CQ values ie. below and note the bold:

52.5
71.25
80.63
85.31
87.66
88.83
89.41
89.71


And, so a :lightbulb: lit up (again) and I thought, hey, why not add in a
feature ( there I go again, hehe.. ) that allows a user to push the CQ a
bit higher. Given the above, at CQ 85.31, I could have bumped it up to
say, CQ 89, thereby saving myself 4 LONG passes !!

Ok, after doing many of these tests, I concluded that its easy to deduce
when to (or not to) bump up the CQ value (manually)
Ok, the first clue is when you notice how the CQ jump just a few notches
(no, not the "matrice" notch hehe) and these are usually just a few CQ
digits. This is our que !! ..to bump up the notch. I realize that this could
be a "user" descrision/descision.

So, what do you think about that ??
