bilu,
is your last compilation working with vobs also?. I guess yes.

@ Digi.Doc

Could you try this one ... it filters more but I could get less average Q values and it made the movie seen in motion more calm and gave less "gibbs" around objects.
(Don't know if its already the one u used)

Code:

intra_matrix=8,13,18,23,28,33,38,43,13,18,23,28,
33,38,43,48,18,23,28,33,38,43,48,53,23,28,33,38,43,48,
53,58,28,33,38,43,48,53,58,63,33,38,43,48,53,58,63,68,
38,43,48,53,58,63,68,73,43,48,53,58,63,68,73,79

inter_matrix=16,18,20,22,24,26,28,30,18,20,22,24,26,28,
30,32,20,22,24,26,28,30,32,34,22,24,26,28,30,32,34,36,
24,26,28,30,32,34,36,38,26,28,30,32,34,36,38,40,28,30,
32,34,36,38,40,42,30,32,34,36,38,40,42,44

It works linear not that exponential-like so it already filters mid/low frequencies more than Notch

You still need http://www.jltoca.uaivip.com.br/files/mencoder_avs.zip as usual, if you want to use AVS files.

Bilu,

First: ... I did/do enjoy your permanent testings along the last weeks! And for shure also to digi.doc and all others which do participate in here.

Second: I give that script-baby a try this evening on my "sensible" source - K19.

I sure am going to need your help now. And from others too, of course

I came from the MPEG-4 world and haven't authored a single DVD yet.
Experienced words aiming for quality are now more appreciated than ever

I came to lmin=2.49:scplx_mask=0.24 by trying to get to the (lowest bitrate possible & lowest acceptable quality) factor. I knew naq would protect the stream from such behaviour (quantize as much as possible), and now I also know it aims to the average bitrate as well.But I needed to test a worst case scenario for the parameters.

About avgTex, I feel it may be better than the default tex^0.5 (square root of tex) in terms of quality, since higher bitrates will only be that much lowered if it's only a peak, not an entire region of the movie. This may be the bitrate delay we wanted

Bilu

incredible · #**468** 04-06-2004, 11:35 AM

Bilu, ...

Try once the matrix posted here: http://www.kvcd.net/forum/viewtopic....=asc&start=461 and tell me if you still need to go till 9800kbit at max! Where when using Notch you also dont have to set Bitrate as max that much .... we should try to end up on 7000 (16:9/anamorph) or even 5000kbit (4:3/non anamorph) as max ... as that would give the average bitrate more space which would mean less quantisation on average movietreatment and only higher Qs at veeeery complex parts.

But enough of theory ... in a few minutes Ill leave my desk in the office to get home for testing.

Try DVDlab Pro Beta Version as it seems promissssssing!
8 possible Audio Tracks, a wonderful menue generator (incl. Previewing of buttons etc.), .. etc etc etc.
http://www.kvcd.net/forum/viewtopic.php?t=10007

But If you just want to burn Single Audio DVD Streams on one DVD, go and have a look at DVD author as it also comes as commandline appl. incl. a GUI - Nice!

I'll start the hard way: http://dvdauthor.sourceforge.net/
Remember I want to keep the cross-platform advantage

I want the complex parts to look good as well

And I trust avgTex, lmin and scplx_mask to help with the rest

I really think avgTex may work beautifully here: not a killer like vrc_eq=1, not as aggressive as tex^0.5, but something that keeps in mind the average complexity of the movie. If the movie is complex it won't affect it as much. If there are only some small peaks it will know how to behave

Bilu

Thats the one I posted as second choice above ... but it does include a simple GUI so you can easely author also on windows ...

bilu · #**471** 04-06-2004, 11:50 AM

I want to go the command-line way because I can automate it better

Bilu

bilu · #**472** 04-06-2004, 01:59 PM

Changed my mind about avgTex: vrc_eq=tex is indeed the better option.

Difference is filesize:

avgtex - 42634 KB
tex - 42636 KB

The bitrate peaks look much better with vrc_eq=tex (same as vqcomp=1) and the rest looks good as well.

I have those files already installed in the same directory as MEncoder...

Exactly the same way as before.

incredible · #**474** 04-06-2004, 03:07 PM

I found the following very importand out....

IF using the latest in here offered mencoder build and setting then vrc_minrate=300:Vbitrate=XXXX ...... I cant control the avgbitrate anymore!!!

Then I changed back to my old mencoder build and ..... everything works well again, means the Vbitrate is respected!

keeping you informed ... actually testing ....

audioslave · #**475** 04-06-2004, 03:14 PM

@all
This is what my MEncoder folder looks like:

Code:

mencoder/mplayer/font/font.desc
mencoder/mplayer/font/iso-8859-1-a.raw
mencoder/mplayer/font/iso-8859-1-b.raw
mencoder/mplayer/font/osd-mplayer-a.raw
mencoder/mplayer/font/osd-mplayer-b.raw

mencoder/mplayer/codecs.conf
mencoder/mplayer/encode2.bat
mencoder/mplayer/makeavis.reg

mencoder/mencoder.exe
mencoder/mplayer.htm
mencoder/settings.ini
mencoder/video.avi > My fake *.avi
mencoder/video.bat
mencoder/video.m2v > The final/encoded MPEG-2 video

Do I need any other files than these

I can't understand why it doesn't work.
BTW It's "mencoder20040405"...

Off-topic: How can I change "Code:" to "AudioSlave wrote:" for example?

EDIT:
Yes I know, I did the slashes in the wrong direction but I hope you still understand

.

rds_correia · #**476** 04-06-2004, 03:38 PM

@Audioslave,
I'm having the same problems as you buddy.
Will post if I find a way to it.
BTW to have Audioslave wrote: instead of Code: use quote="audioslave" between square brackets
In the end use /quote between square brackets again.
Don't forget the slash before the quote!
Cheers

audioslave · #**477** 04-06-2004, 03:43 PM

Thank you rds_correia

! I was starting to think I was the only one who couldn't run MEncoder (mencoder20040405). The previous version was no problem to use but this one is giving me a headache!

I will do the same thing as you:

audioslave · #**478** 04-06-2004, 03:53 PM

Most of the commands in the DOS window works just fine, so my guess is that these following lines has something to do with our problem:

File not found: 'frameno.avi'
Failed to open frameno.avi
Reading config file C:/Documents and Settings/Hea/Skrivbord/MEncoder20040405/MEn
coder/mplayer/mencoder: No such file or directory

The thing is I don't know what kind of files these are or where I can find them. Anyone

P.S. All other commands are okay...

digitall.doc · #**479** 04-06-2004, 04:09 PM

Pleeeaaase, could someone explain me, in single words a "knowledgeless" person like me can understand, why is there any interest in encoding with lowest bitrate possible, apart from avoiding too high bitrate peaks, and making smaller files?. And if the aim is to get smaller files, why is it better to get lower bitrate peaks than raise all quantizers a little?.

@inc,
I tested your matrix. It do give me smaller file sizes with a little decrease in quantizers and bitrate, comparing with notch matrix. But there's something, when you see the film, that's not good. I cannot explain, I'm not an expert. It's like "false" colors, not they are washed, look poor,... sorry, don't find the words. Didn't compare with original, but notch looks more natural.
And I wouldn't worry too much about mencoder respecting vbitrate in 1pass: it will in some fims, and won't in other ones. In the end, you'll have to make prediction.
Related to notch matrix and maxrate, you're right that with notch matrix you need much less maxrate. I even have been testing long time with maxrate=5000 (as with CCE), but I then realised that is better let mencoder raise when it needs at 9800, to encode well bitrate demandin scenes.

@bilu,
I don't remember if I asked before, but did you compare vqmin=2:lmin=2.49 vs vqmin=1:lmin=2.49?. Because in my tests it didn't make a difference. In theory, with vqmin=1:lmin=2.49, quantizers can go down at 1 (isn't it?), but in practice, with lmin=2.49, quantizers keep always above 2.5.
And, as I posted in rate control thread, my settings are quite similar to yours (apart from vbitrate being 9800), but I don't get a difference between vrc_eq values

digitall.doc · #**480** 04-06-2004, 04:11 PM

audioslave,
no, I think we all get this same error messages, but mencoder encodes well anyway.
