NuEnc 0.01b Released

[Peter Cheat]

@Yuri
SegmentedDirectShowSource is not the same as SegmentedAVISource, one uses DirectShow, the other uses Video For Windows (I think). Try SegmentedDirectShowSource and see if the same error comes up (it may or may not). Adding AVI adds complications, the easiest thing to do would be to automatically create an AVS script to handle the AVI. This would obviously not solve your problem. I suck at VFW programming, and suck even more at DirectShow. Sometimes DirectShow is faster, depending on the codec being used (ffdshow has a Huffyuv DirectShow Decoder).

[Yuri]

Thank you, Peter, for your explanation and your contribution.
I'll try SegmentedDirectShowSource.

Best regards
Yuri

if you look back you will find QuEnc has had a few problems with avisource() that were fine with directshowsource() aswell. hopefully those problems are fixed now in QuEnc 0.56. did you try segmented with QuEnc 0.56 aswell by the way ?

[spase]

ok so i have tried both NuEnc and QuEnc with the encodings I was doing, and the stuttering I described was only present on the NuEnc versions.

Here are the command lines I used:
(note: QLB was used on all as the matrix)

NuEnc Command Line Options:

-i ep1.avs
-o ep1.m2v
-b 2148
-maxbitrate 9550
-dc 10
-priority 5
-pass 3
-mpeg2
-vbr
-scene
-qmin 2
-qmax 31
-mbd 2
-cmp 1
-dia 7
-trell
-nocgop
-nointerlaced
-gopsize 12
-maxbframes 2
-aspectratio 4:3
-buffer 224
-dynamic
-rc_var 1
-auto
-close

(minimum bitrate of 512 was set in the GUI)


QuEnc Command Line Options:

-i ep1.avs
-o ep1.mpg
-b 2148
-maxbitrate 8000
-dc 10
-priority 5
-2
-mpeg2
-hq
-vbr
-scene
-nocgop
-nointerlaced
-extreme
-gopsize 12
-maxbframes 2
-qlb
-aspectratio 4:3
-mpeg2mux dvd
-audiocodec ac3
-audiobitrate 160
-auto
-close

the issue doesn't appear to be a problem with over shooting the 9800kbps limit, as some of the QuEnc files jump to over 9550kbps (above the upper limit I set in NuEnc)

additionally, dropping to an extreme low bitrate doesn't seem to be the source of the problem either, as the QuEnc encodes drop below 250 kbps at some points.

for some reason i have a feeling the problem has its roots in the use of dynamic b-frames, but i have absolutely no idea why i think that... must be some sort of intuition or something. I havent had the time to play around with encoding video without dynamic b frames tho.

[dragongodz]

yes i would suggest trying with scene detection and dynamic B frames turned off and see if it still happens.

[spase]

ill give it a go with no dynamic b frames, but scene detection on in QuEnc was ok....

You could also try only 2 passes in NuEnc. There is the possibility that I've overlooked something when implementing >2 passes that doesn't make the stream 100% compliant. I just checked through the code and it seems fine, and its been tested on my standalone, but this doesn't mean I haven't bungled up something.

[dragongodz]

but scene detection on in QuEnc was ok
from memory Peter changed scene detection sensativity(thats right isnt it Peter ?) so that may also be a factor which is why i said you may want to try disabling that aswell.

[Peter Cheat]

It will only throw in more I frames, it shouldn't bugger anything else up.

@spase
What is the source frame rate?, and is the source interlaced?

[spase]

source is 25 fps and is not interlaced.

i am going to play around with this stuff when i get a little more time. finals week is here at the university of maryland, and i will be writing some papers on dogen's zen essays (shobogenzo) and even more other things, so once im done with that i am thinking of doing several test encodes with NuEnc with some opeions enabled/disabled etc.

will report back soon.

@PeterCheat

Hello! I just wanna know if you´ve got a forecast for NueEnc new release. I like of this encoder very much and I´m anxious to try it with new improvements and features.

Keep up on work!:)

TIA,

[Peter Cheat]

Well, I am without a PC atm, my Athlon blew up, and I have to wait for a replacement, *hopefully* in the next couple of days. That's what the salesman told me anyway, and before that he told me he'd have the parts in last week :rolleyes:.

[danpos]

@Peter Cheat

I already knew about your PC issue (you talked about that at kvcd.net ...) and I hope so that you get to assemble your new machine ASAP.:) Anyway, I´m playing with NuEnc 0.21 (test release)that you gave to me and I´m getting very, very good results at low bitrate encodings (1 CD target-XSVCD - I´m getting do it for a DVD movie action source, 104 minutes long, with a good CQ - yep, I´m doing OPV with NuEnc :p ), but that you alredy knowing (because of our talks at kvcd.net forum;) )

Keep up on work!

Kudos,

[Xero_M]

@Peter Cheat

Is ther i chans that you can send ore have a link fore the test release of nuenc 0.21. I cant whait fore the next realise of nuenc, in my opinion the best encoder att low bittrate encoding, and I have tested manny encoders.

[Peter Cheat]

I've borrowed a PC for now, I'll update asap (tomorrow).

[reboot]

What's with all the busted download links?
1b doesn't work at all.
mencode and mirror only give partial/corrupt .rar's/doesn't work.
I think if you want people to use this, you should find some hosting that's reliable, and someone to post a link that stays working.

[Bogalvator]

There's an alternative mirror here:
http://www.petersplace.000k2.com/projects/
(Peter Cheat should probably add it to his sig like he did for kvcd.net...... ;))

If you still have problems, try using a download manager like GetRight etc

@Peter:
Hi Peter,

Hope you get up and running at full pelt soon. Let me know when you have your latest libavcodec changes up on your website, as I want to start integrating a bit of your ratecontrol...as I think ratecontrol is now the biggest issue with QuEnc (now I've got "most" of the bugs out of it ;) )

Cheers,

any news on this?

[dragongodz]

someone is better off asking on the kvcd forum. previous comments in this very thread suggest thats where Peter is posting all his latest news etc.

[Bogalvator]

Just checked and Peter last posted about NuEnc at KVCD.NET forums on 31 Dec, so don't worry, there's no new developments that you're missing out on.

I'm quite sure any news/updates about his work on NuEnc etc will be announced here as soon as it's known as well as on kvcd.net

[dragongodz]

Peter last posted about NuEnc at KVCD.NET forums on 31 Dec
yes and besides the post on the 9th of Jan saying his pc had blown up and the 18th of Jan saying he had borrowed a pc he had not been heard from here since the 10th of December.
also danpos said Peter had already talked about his pc blowing up and he was trying out a 0.21 version he had been sent.

make of that what you will. :sly:

[manolito]

I just found out that Danpos has published a short NuEnc tutorial in Portuguese at
http://www.vmesquita.com/forum/index.php?topic=1577.msg12176#msg12176
The nice thing is that he also hosts the latest NuEnc 0.21 test version.

I don't know if it is alright with Peter Cheat to post the link since he has not officially released version 0.21, but Danpos has only good things to tell about it.

Cheers

@manolito

Hi, guy! I just want to clarify that question. I was also unsure with respect to host a version not formally released for all, but thinking more over I did conclude that I can to do it for the following reasons: 1-The NuEnc version is a test one (beta), which is aimed at development of encoder (test of options, bug tracks etc); so, in this manner,if more people can to test it, more easy and rapdily the encoder development will go ahead; 2-I did a explicit communication that the download version is a non-official release (which will be provide for the owner, Peter Cheat); 3-As a admiring from Peter's work, I did want divulge it in brazillian community; so, I thought that a new version, with more features and fixes will help in disseminate it.

Obviously, I'll like to talk with NuEnc owner (Peter Cheat), but as you've noted, the same is off a very long time. My intentions are the best as possible. If all think that I did a fault, I simply deleted the file from my webspace.

I hope have got clarified that issue.

Cheers,

[freelock7]

Hope to get news about Peter Cheat soon:)
We're all still waiting for its new RC.

[manolito]

NuEnc has a slightly different command line interface from QuEnc, and if
NuEnc encounters a parameter it does not know, it simply quits with a "Bad
Parameter" message. Result: DVD Rebuilder and DVD2SVCD do not work with NuEnc.

Peter Cheat seems to have gone into hibernation, so there is little hope that
he might fix the command line interface any time soon. Since I am a little too
stupid to modify the NuEnc sources and recompile it I decided to write a small
utility that sits between the application and NuEnc and translates the command line
parameters so NuEnc can understand them.

Download at http://scifi.pages.at/manolito/NuCLI/NuCLI.zip

Tested under Win XP with NuEnc 0.01b and NuEnc 0.21. Works with the latest builds
of DVD2SVCD and DVD Rebuilder 0.74 (could not test the VIP versions).


@danpos
I like version 0.21 very much, do you have any idea what Peter Cheat changed
since 0.01b? There is no changelog...


Enjoy

Hi, manolito! I've no idea of modifications applied to NuEnc by Peter, because of I had access only the Nuenc.exe, matrix.ini etc ... I do agree with you with respect to that release, it is really very, very good! I've got very good encodings for MPEG-2 targets (DVD,XSVCD), although for MPEG-1 targets something must be improved. BTW, it is my favourite encoder ATM.

Cheers,

[nnigam]

I have read a lot of good things about this encoder, but where do I get the latest version. All links that I followed go to version .01. I currently am using QuEnc and would like to try this as well.

[manolito]

@nnigam:
Just go 5 posts upward, there you will find a link to a NuEnc tutorial by danpos. At the bottom of this tutorial there is a link to NuEnc 0.21.

Cheers
manolito

[nnigam]

Thanks

I had looked earlier, but obviously not well enough. This time I looked more thouroughly and found it.

[manolito]

@danpos

I have done a couple of encodes with NuEnc 0.21, mainly low bitrate VHS capture to SVCD encodes, and I must say, I am impressed. I used the settings from your tutorial with the BVCD matrix, and I cannot find any quality decrease compared to the original VHS tape.

But I do have a couple of questions, and since Peter Cheat is not available ATM, I guess you are the person to ask:

The settings you propose in your tutorial are all optimized for speed. If I want a better visual quality without too much of a slowdown, which setting would be the best to change? MB Decision from Comp Fn to Least Bits or RD, Compare Fn from SAD to SATD, or Search Size from Diamond 1 to 3 or even higher? Or is Adaptive better? I found that Adaptive 4 is about as fast as Diamond 1, which one would look better?

I understand that you did test NuEnc's CQ mode, and I'd like to know if CQ mode is VBV and bitrate compliant. In other words, is the resulting stream DVD (or SVCD) compliant by observing the Max bitrate? If so, we could have someone (Amnon82, JDobbs or Tylo) write a prediction tool for NuEnc which would give us a high quality one pass VBR encoder which also happens to be FREE.

I'm glad that my humble tutorial has been useful for you (and mayble others :);)).

Well, you must to play a little bit with the settings and then choose the better "cost-benefit" ... I'm gonna reproduce down a piece of readme.txt from NuEnc 0.1:

MB Decision - Alters how the encoder selects a MC MB. Least Bits=high quality (fast), RD=very high quality (slow).
Compare Function - SAD=good(fast), SATD=best(slow)
Search size - Adaptive is faster, Diamond is a little better. Larger value corresponds to larger search size.

In other words, is the resulting stream DVD (or SVCD) compliant by observing the Max bitrate?

Yep, for sure. Since that buffer underflows not occurs, the max bitrate is guaranteed and you get a elementary stream fully compliant. In this way, you must take care with the matrix chose, in order to prevent buffer underflows to occurs.

If so, we could have someone (Amnon82, JDobbs or Tylo) write a prediction tool for NuEnc which would give us a high quality one pass VBR encoder which also happens to be FREE.

I think that will be great a such tool. :) Lets wait that someone have interests to do it!;)

Greetings,

[Amnon82]

If I find time, I'll add NuEnc-Support to one of the next AutoCQ-Releases ...

WOW, that's a great news! :eek: I'd love this AutoCQ release! ;)

Any working link for 0.01b?

[L.H.V.F.]

Hi

For anyone interested in NuEnc, and their original variants (NuEnc 0.01b - NuEnc 0.21 - NuCLI), I had solicited to manolito forum member:

Binary and Sources (http://www.mediafire.com/?64c1b0ymgvtbnjo)
