@All,

This is still experimental, but here's the first version, which I've been playing for the last couple of hours, and it seems to be doing it's job
The functions used are shape adaptive blur

Here's your filter line, suitable for DVD encodings:

hqdn3d,sab=0.5:0.5:1,noise=3th

Note:
That's line goes AFTER your scaling and cropping commands, and BEFORE the final expand command.

When I finish optimizing the values, I'll post it on the optimal script section, just like the MA script posts.
In the mean time, have fun, and post your comments here

We remove also the current two unsharp filters?

You do noise on Chroma also ? Won't this be noticiable ?
Eye is far more sensitive to noise in chroma than in luma.

@Maurus,

It's already been taken care of, by the shape adaptive blur and the smart blur.
It basically does the same as unsharp, but more efficiently, because shape adaptive blur is not static, but dynamic (adaptive).

@Phil,
Yes, but the noise level is so low that it can barely be seen by the eye. But the noise on the luma+chroma channels gave me a more flat Q curve, that when applying luma noise only.
Do a small sample, and check it with Bitrate Viewer. You should see a more flat qreen line.

Does that mean also a higher Q on dark parts where these parts "before" ading the chroma-noise ended up in lower Q. As this would be risky on underwater parts.

If not that would mean the average of the Q is rised a minimal bit (just IMHO!).

So a flat Q curve is not the factor on which we should end up, more Q dynamic means less bitrate chaotic-dynamics as the encoder gots room to breath in its quantisation which "would" calm the Bitrate dynamic a little IMHO

@Inc,

Yes indeed, the bitrate is more balanced and distributed.

@All,

I've been doing some serious reading and parameter optimizing, and here's my latest stuff (not final yet!, and probably never will ).

Following are two samples, one 704x480 at an average bitrate of 698Kbps, and another sample, also 704x480 but target average bitrate of ~6,000Kbps, which in reality came out to 1,437Kbps, because quality factor was fulfilled by the encoder, and no need to go higher in bitrate. Both are from the same "Red Planet" test clip, for consistency. Average bitrate measured with Vdub, because average given by Bitrate Viewer is always incorrect (gives lower values).

672Kbps (Real 698Kbps) average bitrate graph:


Sample here:
http://s2.yousendit.com/d.aspx?id=BF...A956C60D831C05



1,340Kbps (Real 1,437Kbps) average bitrate graph:


Sample here:
http://s2.yousendit.com/d.aspx?id=47...C50CDBB2CA6261

And here are the settings used for the samples:

Code:
hqdn3d=2:2:2,sab=1:1:8,smartblur=.5:.5:20,noise=3th:3th
And the common encoding parameters:
Code:
lavcopts=vcodec=mpeg2video:vstrict=-1:vmax_b_frames=2:vrc_maxrate=9800:aspect=1.3333:keyint=18:vrc_buf_size=1835:preme=2:precmp=2:autoaspect=1:vrc_eq=tex:scplx_mask=0.01:vqmin=2:mbqmin=1:lmin=0.01
Both samples were encoded using a set MAX bitrate limit of 9,800Kbps.
The small sample had set 700Kbps as vbitrate and the large sample had 6,000Kbps set as vbitrate.
For obvious reasons, filtering, the peak bitrates can't reach higher values, because the material is being blured on motion areas, in a similar way like the MA script. Actually the blur is on objects, so it's not on the complete picture, which is really what we want.
But the results I got with these values, could be the bitrate normalization that we are all looking for

@Kwag: Are these parameters for DVDs sources, AVIs sources or both?

Kwag, why did you set Vqmin=2???
Ok, the manual says dont go under but as we figured out a vqmin=2 would result in blocks on dark underwater scenes for instance as the quantizer wont go under the q=2 limit (vqmin) on these scenes and mencoder on these scenes at q=2 produces blocks!

Try one at vqmin=1 (for shure) and lmin=0.1 (play with lmin) and tell me your results


EDIT:
Yep as I did assume, i saw the 670kbit one and it gots a lot of blocks especially in dark areas thats cause of an average Q of 5!!

The high avg sample still gots blocks on dark scenes as you set vqmin=2 and cause of the "flat" q curve.

The high one you could encode only using vqscale=2 that would be the same

Thanks for pointing it out. It should be 1, not 2.
All other parameters are correct. I just verified them.

Much better
This is from another encode (The first 3 minutes of "Space Cowboys" )

That is what I just downloaded from the link above. Now we have the answer to "how much time a link can be DLed".

It would be great if everyone that downloads it, automatically puts it on the E-Mule "Incomming" folder. That way, we automatically start sharing sample files
W can use the site 'yousendit.com" as initial distribution, and then all (most?) people that download it, share it

I like that idea. I'm downloading just now.

This is great! I was wondering if you could post your complete command line, please? Your 2 pass *.bat with this new MA routine...

BTW How much do the 2 methods of encoding (With MA/No MA) differ in time? In other words: Is the line with the MA mimicking much slower?

Hi audioslave,

Just put the filter line I posted above, between the crop, scale and expand.
My resizing values won't make sense to you, because they are different for every movie. Use PackShot or MencodeME to get your initial configuration file, and then edit the file with the parameters I posted above. All samples were 2-pass.

It's much slower with the adaptive filters, just as it is with the MA script.

Yes it is. By about half

If you want an other option that will divide the speed again by 2, use -mbd=2

I'm curious about the result on the bitrate but I don't have the time to test it (btw if someone can share a source sample he use for its test, I can't find any that gives me enought underflowbuffer to do some research on how tp avoid them).

I just encoded a movie with the mencoder pre alpha build and your filter the quality is great the bitrate is just way to low :S and the noise=3th didn't seem to work. And I made a couple of mistakes it turned into a 720x480 movie and I don't know why can anybody tell me what I've done wrong.
Thanks in advance

Oke nevermind the bitrate that was my mistake but can anybody tell me why its 720x480?
