Hi friend,

I have a big problem.

I encoded 2 DVD using xvid codec koepi "XviD-Koepi24062003" unstable version.

Avisynth script created with gordian knot, first DVD (source NTSC) with IVTC, neutral bicubic, second one on PAL same thing but without IVTC. WIndows XP Pro + AMD 700 + ati radeon 128 mb memory + 512 mb ram.

I uses a Doom9 guide for optimal xvid setting codec.

1 pass:

6 - h.263 - xvid - 4 - 250 - 1
use croma motion flagged only
b-frames control 2-150-75
dx50... flagged

2 pass int:

6 - new modulated - 4 - 300 - 1
b-frames control 2-150-75 (lumi masking flagged)
quantization 2-6-2-16

two pass tuning:
I-frame boost: 5%
below i-frame: 5

alternative curve:
actived - medium - 500-90

debug: chroma optimizer fagged

1 CD, bitrare 870

aparentrly no problems, very nice image

I use koepi decoder, I also tried all xvid decoder codec, I tried ffdshow filter too... Image on my PC it's very nice, fluid and definite, really "fluid".

I shared, some peoples downloaded, now there are many peoples that have problems to decode...

50 % of peoples have no problems using every kind of xvid codec to decode.

50 % of peoples have "sobbing" (skipping) problem to decode the 2 movies, normally they don't have same problem with all other AVI/Xvid movies.. they told me thy tried many solution, all xvid decoder (Koepi, Nic's, Umaniacs).. Some of that finally watch good with nic's stable decoder, some othe using ffdshow filter only, some of that did not resolved the problem ???!!!??? what's up, i have any problem to decode??!!

I give a copy to my brother that he know situation, it's a programmer, he know many this about codec, windows, hardware.

using a pentium 4 2.000 he has the same problema image "sob", image go ahead and behind every seconds. Is now trying some other decoder (now is using yours one, koepi)

Do you know what prablem could be??????

that information datas are full (i can watch it very well, so I think in the compression info datas are full).

could you help me???

ciao from italian friend

Your settings are not really optimal...

- Don't use modulated quantization type together with B-frames, it's broken. Apart from that it's not mpeg standard compliant
- Don't use different max I-frame settings in the passes
- Lumi masking doesn't help in current state, don't enable it

Take a look at Snowbeach's guide (http://forum.doom9.org/showthread.php?s=&threadid=56709)

jmtc - just my two cents :)

Cheers

What Nibor said.
I use koepi decoder,No you didn't, XviD directshow filters never try to decode DivX5 files (DX50 fourcc).
they told me thy tried many solution, all xvid decoder (Koepi, Nic's, Umaniacs).. Some of that finally watch good with nic's stable decoder, some othe using ffdshow filter only, some of that did not resolved the problem ???!!!??? what's up, i have any problem to decode??!!Just one more thing - the recommended decoder for XviD is ffdshow. The people who resolved the problem probably used ffdshow to decode *divx* (not xvid) - so ffdshow took over this file and decoded it fine.

Use fourcc changer (from Koepi) to change fourcc from DX50 to XVID and you'll be fine with all xvid-capable decoders, not only with ffdshow.

@sysKin
I think he meant the divx compatibility (if it's called so, I'm not at my computer), when he wrote dx50 flagged. You know, this bframe frame reordering stuff. IIRC it's an option you absolutely recommended.
Best regards,
JimiK
Edit: Last thing: I hope 'he' is really a he :)

Sorry split710it... I just haven't used dev-api-3 for such a long time ;)

Okay, so, I dunno what happened, but in general use ffdshow for decoding, and only if you have any problems with ffdshow, try different decoders.
One of the different, which you can try, is 3vix.

Good luck,
Radek

Thank's JimiK and sysKin for answer but I think you are making confusion.

I never mentioned Divx codec ??!!??

I'm just speaking about Xvid codec. (for encoding and decoding)

I have that Above mentioned problem with Xvid codec
