where is the speed?

[Ruppl]

Hi all,

i´m new to avisynth 2.5. I have installed it and the Plug-In Pack,too.
My Problem is, that the encoding isn´t faster than before with mpeg2dec.dll!!
My Framerate is about 10-12 fps, with an AthlonXP1600+.....:mad:

I´m using Gknot, here is the avs-script:

LoadPlugin("I:\VIDEOT~1\Gknot\mpeg2dec3.dll")
LoadPlugin("F:\Auslagerung\Avi Synth 2.5beta\Decomb.dll")
mpeg2source("F:\RIPPEN\Projects DVD2AVI\Disc1 - Titel 3.d2v")
FieldDeinterlace()
crop(8,0,708,574)
BicubicResize(704,528,0,0.75)

What is wrong??

P.S: Fast recompress is on(VDMod)

That fourcc and codec is vdubmod reporting in File/File Information?

What codec are you encoding to in vdubmod?

Have you compared the speed using the same avs-script? In the one you posted you're using a very high resolution which will make encoding slow (and on top of that a deinterlacer)

Decomb for 2.5 is not yet low-level optimized as Decomb Legacy is. At least for Decomb at this time, any gains from using YV12 are offset by this fact. Try the experiment omitting FieldDeinterlace() to see if you get speed gains.

neuron2 -

when can we expect an optimized version of decomb? are there any major feature additions/bugfixes on your todo list before you do that? just wanted to ask because i use decomb very often and it is really a great and helpful tool.

@ Shodan

I´m using the DivX 5.02 Codec.

fourcc= YV12
decrompessor= DivX 5.02

@ neuron2

I´ve tried it out without the "FieldDeinterlace()", but there are no speed ups...

Not for several months. I'll be going to India again for a month very soon and I have a lot of non-Avisynth stuff to get done before I leave.

@ all

Ok. I´ve used an another source and script:

LoadPlugin("I:\VIDEOT~1\Gknot\mpeg2dec3.dll")
mpeg2source("F:\RIPPEN\Projects DVD2AVI\Disc1 - Titel 1.d2v", idct=2)
crop(10,0,702,574)
BicubicResize(544,400,0,0.75)

Now i had a framerate about 22-28fps -< firstpass and int the secondpass about 35fps, without any deinterlacer. Which deinterlacer is fast and works with YV12?

[lamer_de]

look at avisynth org for a listing of yv12 capable plugins. Speed greatly depends on search effort etc, so I don't dare to give a general recommendation. Toms MoComp would be my choice for deinterlacing, but that's just me

CU,
