XVID quality - very strange thing?!

[s2001]

Dear All!

I'm newbie in XVID encoding, but have good experience with DIVX & WMV formats...
Could you please help me to get high-quality XVID-encoded clips?

I know that XVID may produce very good clips - I use AutoGK to encode DVD->XVID and I see very good quality! But, I can't achieve the same results with manual (DV,MPEG2) files encoding :(

I already read XVID DOOM9 guide and use VirtualDUB 1.5.10 for encoding - I always get poor quality for files with comparable size. I'd like to prepare XVID file with quality >= WMV9 file - with the same size...

Could you please tell me, what settings exactly should I use to make XVID clip with higher quality vs. WMV9 and size less or equial vs. WMV9?
In another words, I'd like to produce the same high-quality files as it may be done with AutoGK :-)


Thank you in advance,

Best wishes,
Sergey

Perhaps you should describe your current encoding process and settings?

It is pretty difficult to tell you what are you doing wrong if I don't know what are you doing.

Did you read Crusty's FAQ (http://www.vslcatena.nl/~ronald/docs/xvidfaq.html)?
It's very useful and helped me a lot.
Thanks to Crusty!

Hello,

Thank you for your reply!
I use VirtualDub with the following settings:

1st pass - no changes from defaults
2nd pass - 3000 kbps bitrate, AS@L5 profile
No resize (720*576)

In this case I maid clip with size ~20% more vs. WMV9.
And I got interlaced file...

Could you please describe me, what settings should I use to produce non-interlaced files with reasonable size?

Thank you,

Best wishes,
Sergey

Compressibility test is the key here (it might be possible that even for such large resolution even such high bitrate is not enough) as well as usage of avisynth filters to remove interlacing...

Thank you! Could you please tell me, is there the similar to AutoGK tool which may process clip automatically? (like Dr.Divx for Divx) :-)
Which may take care about interlacing, bitrate, etc...

It may be great help to newbie in XVID :-)

Btw, if you have mpeg2 sources (not necessary VOBs) you can still use AutoGK (see my FAQ). In case its uncompressed AVI then with a bit of tricks you can use regular GK to perform encoding steps semi-manually.

We can move this thread back to GK forum if we start discussing second option.

Thank you! Could you please move it to GK forum? It would be best to use GK, if it's simple task for standalone files... :-)
