Mencoder: Very Fast with Makeavis

[maurus]

I have made my first KSVCD with MencoderMe. Thanks a VMesquita for this great and fast tool.

Directly from the VOB (filtering combo selected DVD) the speed is 8 fps.

From a script avs, using MakeAvis (and filtering combo selected MakeAvis) the speed is 15 fps.

It is this good?

I thought that directly of the VOB it was the fastest option...

This is my script:

## DLL Section ##
#
LoadPlugin("C:\Filters25\MPEG2Dec3.dll")
LoadPlugin("C:\Filters25\undot.dll")
#
Mpeg2Source("c:\film\***.d2v")
#
undot()
BicubicResize(480, 576, 0, 0.5)
MergeChroma(blur(1.5))
MergeLuma(blur(0.1))
#
#

Another question. Why I must set the size video in both script .avs BicubicResize(480, 576, ...) and the Final Resolution combo in MEncoderMe?

Thanks for all.

a) It seems you got an old build of mencoder as direct vob input land a dest. size other than 704 width lets perform in mencoder the scaler: engine, and it could be that your mencoder build still does a colorconversation when doing the scaler: parameter ??? Thats why VOB input+ resize via mencoder could be slower.

b) Do you got your movie as "1file" VOB on your HD??
If yes theres no need to go via Makeavis .avs as the filtering above in your avs script is possible using mencoders internal filters (see the "crop/resize etc, "-Thread in here).
So be shure you got the right mencoder build and then youll see that direct VOB input makes the whole thing about 10% faster!

Just BTW ... as you use Bicubicresize using ...,0,0.5 ... you also can use Biliniear resizing which reiszes softer and therefore you can drop the MergeLuma(Blur(0.1)) line. As it makes no sense, to resize using a sharpen factor and afterwards blurring again

c) in MencoderME you can gain from a MakeAVIS template which does not provide OTHER resizing commands to mencoder when doing the encoding ... as you already determined the resizing via avisynth & Makeavis!

I use MEncoderMe 0.23 (Mencoder build 04/30) and I use 1 Big VOB.

What is the best quality method for make KSVCD (MPEG-2) with MencoderMe 0.23?

1) AviSynth + (Filter combo MakeAVis)?
2) VOB + (Filter combo DVD)?

Can I use Filter combo MakeAVis directly from VOB?

Thanks.

You can use both alternatives. But I recommend getting a different mencoder build, two people reported at the portuguese fotum that this build was a lot slower and replacing with Inc's build fixed the problem.

[maurus]

Wich of this Inc's builds are good for my Athlon 900 Mhz (not XP)?

Yesterday, I have try Inc's mencoder.exe for Athlon build (05/02/2004) and it not work for me. I replaced only mencoder.exe in MEncoderMe 0.23, must I also replace Mplayer.exe and cygwin1.dll?

The build included in MEncoderMe 0.22 not work for me.

The build included in MEncoderMe 0.23 work for me, but is slow. However, using Avisynth+MakeAvis+MEncoderMe is too more fast.

Thanks.

(as named Athlon XP in there)

Uops .. I see you dont have 3dnow??
Well I dont know which instr.sets are supported for each CPU!

Can someone give me a link where a detailed listed table is avaibale in the www?? So I can compile several CPU versions.

EDIT:
Found it: http://www.qvctc.commnet.edu/classes/csc277/i_sets.html

I have Athlon K7 and yes, it have 3dnow.

Thanks.

Did you try this generic build one?
http://home.arcor.de/ffvfw/Intel+XP_...r-20040502.exe
As it was compiled incl. CPU runtime detection.

[maurus]

Thanks. I will try this replacing in mencoder.exe in MEncoderMe 0.23.

I replace only mencoder.exe in MEncoderMe 0.23 or I must also replace Mplayer.exe and cygwin1.dll?

EDIT: I think only mencoder.exe...

Leave the CygWin1.dll as its the same one. But you also should change the mplayer.exe with the (general CPU) one as both are outputtet from the same compile process.

Yes, now I have try generic build 20040502 and the new build 20040506.

Both works for me. I have a AMD K7 Thunderbird 900 Mhz.

Builds for AhtlonXP not works for me. It would be good that somebody compiled a version for classics Athlon.

Is some advantage in using your generic builds to use the current included in MEncoderMe 0.23?

I try both with option DVD in Filtering Combo,and the speed is the same (9 fps).

Thanks.
