Looks like there should be a "low bitrate" template and a "high bitrate" template! Nice discovery!

Actually adjusting the spatial complexity masking had already been mentioned in another thread.

http://www.kvcd.net/forum/viewtopic.php?t=10391

I can remember using a value of as small as 0.1 back when I was using ffvfw and my filesize would decrease by as much as 25%

Are MencoderMe results equal or better with internal Mencoder filters than with avisynth optimal scripts?
Does internal Mencoder filters reduces final filesize?
How mencoder file size prediction or calculation work while it is encoding?

@VMesquita & Dano

Well I dont know if still two templates are nedded, cause that "dicovery" I made already many weeks ago. It reduces also the "barrier" of B frame quantisation. And makes sense as I still can use Vbitrate and it results almost accurate on 1pass - as you see above.
Cause Dano, I dont want to get bigger filesizes generally, I want to kill that resulted avergae bitrate limit

@ Prodater

Yep, they do lower filesize as they do treat noise etc. like avs but we have to figure out what will be better avs or mencoder filters (I did post in here a screen where also postprocessing parameters are explained).

Prediction: I do set Vbitrate to the wanted avg bitrate and do a slicer() encoding ... in 95% of cases it matches veeery near at the first run, and then you do fine adjust by using another bitrate untill it matches. When using mencoder I do need max 3 pred. turns (ping-pong-ping)

Congratulations for the MEncoder-Me.

Now, very easy question:

¿What is the GOP for PAL KVCD or KSVCD? ¿15, 18, 24 or 25?

A curiosity:

¿How about of internal MEncoder resize? ¿Lanczos? ¿Bicubic?

Thanks.

15 = PAL KDVD
18 = PAL KDVD

24 = NTSC KVCD
25 = PAL KVCD

as you can see the sws parameter, there the interpolation method is determined by a value i.e. 9 .... go into the mencoder readme and see whats about the values.

just compiled my own mencoder.exe under windows for athlon and i works great, on tests over 3 sources i get an extra 3-5 fps on my encodes .

@vmesquita

keep up the good work on this gui it rocks

I can't use MEncoder-Me 0.2 in my Athlon 900 mhz? only over Pentium?



Thanks

Yes you can... I have a AtlhonXP 2000+! What is the problem, exactly?

I say it for this thread, where several people are compiling MEncoder for Athlon.

He is better (very fast) to use the version offered by Krassi or another version of MEncoder for Athlon in MEncoder-Me 0.2?

Thanks.

Sincee you have an Atlhon 900, you need to use a generic build. Atlhon builds are actually for AtlhonXP that supports SSE. MencodeMe comes with a generic build

Ok, I will try this nigth MEncoder-ME 0.2 for make KVCD or KSVCD from a DVD.

Thanks.

Is that compile done frome the latest CVS? And ... can it handle makeavis generated fake-avi files?

If yes What did you use MinGW or CygWin ? And how did you set it up to get makeavis working? (I changed the codecs.config to VMesquitas one before compiling but finally that resulted mencoder.exe will not encode makeavis sources.

Thanks for your reply
Inc.

PS: I heared, that the newest CVS gots a fix that when using :Scale= ... it wont change the colorspace to RGB anymore .... is that right?

@incredible

It was the latest cvs MPlayer-20040421.tar.bz2

I used MinGW to compile, I have not tried a makeavis avi yet, going to try tonight

I think the build included with MEncodeMe doesn't do that anymore, look at the logfile:

Try something like scplx_mask=0.03 and see if your bitrate goes up.

@Vmesquita

A big thanks for a job well done.
Yes Dano, scplx_mask does "I kind" of filtering. In man_page it's advised to deblock when no other deblocking filter is used.. But if you use makeAVIS, that is, if you frameserve to mencoder through avisynth a already filtered image, I don't find the need to filter else with scplx_mask.
When encoding directly from unfiltered source (like a vob), even more if no filter is applied at all, I'd advise to use it at least at 0.2

Well, inc, you're right. By default, if I frames get a quantizer of 1, B frames will get (I*1.25)+1.25=about 2.50 quantizer... And in a GOP we have at least (when GOP=15) 10 B frames for each I frame... With your method you gave B frames a minimum quantizer about 1.50.
I'm still struggling with my microblocked encoding of StarWars II. Postprocessing helped a little, as helped filtering. Raising scplx_mask also helped. But they're still there, mainly in dark flat surfaces, but also all over . I thought it could help lowering quantizers...
A way to lower quantizers when vqmin=1 and mbqmin=1?. Try lowering lmin, for instance lmin=0.75... quantizers lower. Of course, lowering B quantizers also is of a help.

I did set lmin=0.1 .... by this I can go up to approx. 4000kbit avg! if I want ... and if I set lower to i.e. bitrate 3000kbit .... I get a 3009kbit avg resulted file in 1pass mode .... sexy! I think your way digi.doc a) makes more sense and b) does it well the same!

thanks!
