[Koepi]

Ahoy,

finally it's there.

Changelog:

XviD-12052002-1:
- EPSZ and EPSZ^2 activated.
- INTER4V code cleanups/improvements
- Disabled hinted MVs on 1pass modes, 1pass works again.

Additionally, I removed NIC's DSF since it didn't work with the new dll anymore.

Best regards,
Koepi

Good,
can we know a bit more about this? :)

[Koepi]

No, you can't :P

Just kidding.

Those modifications by chl mean:

Use INTER4V only if neighbours move different than current block. Save quality, some speedup.

(copy'n'pasted from CVS log).

Those are the most important changes to CVS since my last binary from 02.05.2002.

But the 1pass fix is made by me and I don't have CVS write access, so have fun ;)

Koepi

Perhaps am I really dumb, but the binaries don't appear on your website !

[Koepi]

try hitting SHIFT (hold the key down while) klicking on "refresh" or "reload" (depending on your browser).

This will instruct your browser to tell the proxy you're using to reload the page from the net and not just use it's cache.

Yes, now it's here, thx a lot.

Hi,

I already changed some values back in current CVS.
The "neighbour-movement" idea really is faster, but I found a clip where results were worse, so I changed threshhold.

Maybe you try yourself which is the best value for NEIGH_MOVE_THRESH.
Also, please make sure you use CVS version with
motion_est.c: version 1.17, 2002/05/12 17:21:30

Before that, there was a bug for non-INTER4V modes.

Hi,

thanks gruel, I found the changes already and uploaded another binary - the board wasn't reachable and I had to capture a documentation which took longer as expected, but here we go:

XviD-12052002-2 _ALPHA_ Release

Based on CVS from 12.05.2002 21:00h MET...

Changelog:

XviD-12052002-2:
- EPSZ and EPSZ^2 activated.
- small INTER4V bugfix
- Disabled hinted MVs on 1pass modes, 1pass works again.

@Koepi
I quote;
XviD-12052002-2:
- EPSZ and EPSZ^2 activated.


With reference to build Xvid-17042002-1 which also stated EPSZ and EPSZ^2 activated. Does this mean that this prior build didn't have these things activated? What was xvid using prior to this latest build?

Am I likely to see an increase in quality between one and the other? Also can you spare me a few words to explain in detail what these different modes do anyway? I've read Doom9's explanation in his xvid guide but I'm still curious for more detail.

Thanks in advance

[Koepi]

Gazza,

next time, USE the search, we already lost some words about EPSZ / EPSZ^2.

It is a different motion search algorithm (the "normal" builds from CVS like uManiacs use PMVFAST algorithm).

PMVFAST tends to prefer small movements of "static" areas over keeping them static, EPSZ / EPSZ^2 should work better in this respect. EPSZ is supposed to better find non-linear motion in series of frames.

And I always have to activate that code since it is for testing purposes only yet and thus disabled in CVS.

Regards,
Koepi

koepi, do you have any idea if your build does contain that "grey block" fix that was recently discussed at xvid.org forum?

[Nic]

Hiya :)

http://nic.dnsalias.com

Exactly the same as Koepi's build, but with working DirectShow Filter & with a slightly new MiniCalc ;)

Cheers,
-Nic

ps
@Koepi: Thanks alot for the codec.c update :) (for 1pass MV hints fix)

@OUTPinged_: Yes that fix is in the CVS, so both mine & koepi's has that fixed. :)

XviD-13052002-1 _ALPHA_ Release

Based on CVS from 12.05.2002 21:00h MET...

Changelog:

XviD-13052002-1:
- EPSZ and EPSZ^2 activated.
- small INTER4V bugfix
- Disabled hinted MVs on 1pass modes, 1pass works again.
- ^all the same to 12052002-2 but reincluded Nic's DSF.

Thanks a million Nic for sending me the new DSF :)

Best regards,
Koepi

PS: Outpinged, the bugs are fixed in CVS, so they don't simply "re-appear"

Ahh! Don't you just love the smell of a fresh compiled xvid build?
:D :D

Grin.

[OUTPinged_]

One more question, which motion search precision values will enable EPSZ and EPSZ^2, accordingly?

[R3g]

AFAIK :
EPSZ -> MP 5
EPSZ^2 -> MP 6

[Koepi]

Uh, wrong.

EPSZ activated means that PMVFAST is replaced by EPSZ, thus EPSZ is active in my builds in all levels except for 0...

Search precision 6 activates EPSZ Squares.

But even this got answered some more often here already....
