Avisynth-can i optimise scripts?

[SerbianBoss]

Hello everybody,

Few days ago i buy A64 X2 3800. Processor is good and work twice faster but i was interesesting about avisynth.

With new processor i have speed up just 30 second in avisynth. This is very small and i ask can i avisynth or my script speed up.

This is script which i use. I use convolution filter at high noise reduction because only than i got excellent result.

LoadPlugin("Convolution3d.dll")
avisource("D:\CAPTURE\capture.avi")
ConvertToYuY2(interlaced=true)
SeparateFields()
odd=SelectOdd.Convolution3D (1, 32, 128, 16, 64, 10, 0)
evn=SelectEven.Convolution3D (1, 32, 128, 16, 64, 10, 0)
Interleave(evn,odd)
Weave()
crop(8,4,-8,-12)
AddBorders(8,8,8,8)

So, when i have Athlon 64 3200 it took 1 minute and 55 second to render to mpeg2(720x576) and now with Athlon 64 X2 3800 it took 1 minute and 30 second to render to mpeg2(720x576).

I capture with Canopus ADVC 110 to DV avi and with CCE and avisynth i render to mpeg2(720x576).

Again, question is: Can i optimize my script or something to work faster with avisytnh.

best regard

Hi-

See if this thread helps you to get faster encoding:

I think his work will be integrated into AviSynth pretty soon.

thanks for info.

How to implement this in my script.

I copy MT.dll in avisynth in plugin directory and copy avisynth.dll in system32.


But question is what next? How to implement in this script

LoadPlugin("Convolution3d.dll")
avisource("D:\CAPTURE\capture.avi")
ConvertToYuY2(interlaced=true)
SeparateFields()
odd=SelectOdd.Convolution3D (0, 32, 128, 32, 128, 10, 0)
evn=SelectEven.Convolution3D (0, 32, 128, 32, 128, 10, 0)
Interleave(evn,odd)
Weave()
crop(8,4,-8,-12)
AddBorders(8,8,8,8)

thanks

Did you read the link ? It explains pretty clearly how to use MT in your scripts

I get excellent results when i just add SetMTMode(2) at first line.

SetMTMode(2)
LoadPlugin("Convolution3d.dll")
avisource("D:\CAPTURE\bmw.avi")
ConvertToYuY2(interlaced=true)
SeparateFields()
odd=SelectOdd.Convolution3D (1, 32, 128, 16, 64, 10, 0)
evn=SelectEven.Convolution3D (1, 32, 128, 16, 64, 10, 0)
Interleave(evn,odd)
Weave()
crop(8,4,-8,-12)
AddBorders(8,8,8,8)

Now i have 100% speed



I think that i just need to add SetMTMode(2).

So how long does your test encode take now? Are you almost down to a minute? If it works for you, you might post in that thread and thank the guy.

I post on doom9 and write my test.

I test with 17 minute Dv avi and than encode to mpeg2 720x576 using CCE. It took 36 minute in 2 pass CBR.
I just wondering does my script is OK(i mean for SetMTMode(2) ?

Now i have one error.

When encoding begin, few minutes after it sais:

Mux video buffer overflow.

When i try without scrip everything is OK. What can be this?

Sorry, I haven't installed my dual processor yet. I think you should ask in that Doom9 thread.
