SBC encoding did not go well ...

[Nadav]

I've Ripped my DVD to the HardDrive, the Vobs look and sound good and I wanted to make the best Divx with Nandub SBC encoding method (which intend to Produce a better result in Divx).

I Choose to Frameserve from DVD2AVI, so I saved the Movie
Project in .d2v file, then I used in VFAPIConvEN to convert the
.d2v file to a fake AVI.

I've Opend the faked AVI in Nandub and from there I continue
as Follow in this guide:
http://nickyguides.digital-digest.com/nandub.htm
(First making an 1Pass state File ... until I got to the level of saving as AVI).

Finally After several Hours I got the Divx Encoded in the size I want and even the Properties looked good but when I opend the File I didn't expected to discover that the quality isn't good (picture), actually I got Better result in DVDx 2.0 (in the same file size).

I don't Understand What's go wrong, I did exactly as mention in the guide except that I added the Audio in MP3 VBR too (perhaps
I wasn't supposed to add the sound yet? but later?)

I want to mention that the movie was 25 FPS in pal and Full Screen, length of 85 minutes. - perhaps there is a spicial setting for this kind of movies ?

Thanks in advance for any reply .

click on my upper anigif and compare the the nandub routines i describe.

i'd suggest to use gordianknot + divx5, however.

you will find guides on both.

[Nadav]

Besides, I already Know How to encode with divx 5,
I just want to make it with SBC divx 3 methode now :-) .

What's the story with the chicks in your site ?

What video bitrate and resolution are you using? And are you using the more current nandub 1.0rc2? That guide you are using is referring to an older version of nandub.

[Batman]

The doom9.org sbc guides are a great resource that you should read.

[Nadav]

perhaps that's the problem ?
So where shuold I find an updated guide?

and I've used the calculated bitrate (959 - sould be OK right?).
also the resolution was 512X384 as acceptable, right ?(pal - 4:3)

In Doom there is a guide with GK and I already tried GK and not go well - it to much complicated and not even work for me, so I choose to use VFAPIConvEN to convert the .d2v file to a fake AVI and opening in NanDub.....

:confused: :confused: :confused:

[UncasMS]

the guide i was referring to is based on the latest tools/version and was meant for comparison.

and there is no story behind the caprice bourret pics.

You do need to experiment around with the nandub settings to find which work best. There is no single setting that will work perfectly for all materials (though there is indeed a range of values that will work well enough for every parameter ;) ).

[Nadav]

as subject say.

[Enchanter]

You're welcome.

Just keep in mind that Doom9's guide will not necessarily help you get the result you want. That's where experimentations come in. ;) Have fun.

[Nadav]

but the result is still bad !!!

I canoot make experement with 4 Hours encoding !

[Nadav]

if u want some information, I'll do the best to provide it for U.

Just Please Help me to use SBC encoding as well,
I've expirince in many things in Divx and using VB but
I can't get good result in SBC and I really want to get over it.

[Enchanter]

Outline to me some of the SBC settings that you are using. In addition, describe to me what you mean by bad or not good (ie. how bad is the picture? Macroblocks, warming, etc.?)

[Nadav]

The picture looked like I've set the bitrate to 300 (although the bitrate that I set is 955).

the picture don't have any blocks or a somthing like that... I'll try to upload a picture. (right now I'm trying to encode the movie again based on Doom's guide - Hope For Good !)
See ya later in 5 hours.

[Nadav]

And seems that the quality is much better now (compared to the encoding that I make before).

I also forgot to mention that the sound was vbr 128 - 360 and sized 100 mb and seems to me that most rips are at 50 mb more or less a few mb, so I think that I could make a much quality rip
if I was do a 32 - 128 vbr audio and spare the mega bytes for video encoding.

I wouldn't actually want to bring down the audio quality lower than 128kbps. As long as your video bitrate is sufficiently high, that should do (959kbps is good enough to me).

A few things that you might check that you have done:
1. Check that the STATS file has indeed been generated and selected in the Bitrate Curve tab
2. Enable Curve Compression. Depending on each movie, you will have to select a value (try not to go higher than 25%). If the movie contains mostly low-motion scenes, with only a few instances of fast-motion, choosing a high compression value is wise. Use lower compression if you are working on a source with relatively a lot of fast-motion scenes
3. Try not to force the min allowed bitrate and high-pass values too high. It's not doing you any good, unless you happen to be working under very low bitrate
4. Increase the Payback Delay and enable 'corrections on low-bitrate conditions'
5. Use a DRF of 2-8. I've been using this anyway and everything's fine to me

[Nadav]

was in the Doom's guide and I follow him, please explain:

* In how much to increase Payback Delay? (45 sec is selected)

* I have inserted the state file in the "Encode Using" line,
what about the "Collect in" line? should I put the state file in there too?

I'am using --r3mix VBR Sound settings - Is this good? I've heard that ABR is much better or what?

Again thank you very much for your help . :)

[Enchanter]

In how much to increase Payback Delay? (45 sec is selected)
I usually increase it to the max 120sec.

have inserted the state file in the "Encode Using" line,
what about the "Collect in" line? should I put the state file in there too?

Just make sure that the STATS file generated has been selected by the encoder. You are fine the way it is now.

I'am using --r3mix VBR Sound settings - Is this good? I've heard that ABR is much better or what?
I'm only using the LAME --alt-preset settings. I've not been an active participant in the MP3 scene, so I can't say how good your choice is. :)
