Hi,
I try the plugin Neat Video with Virtualdub.
First i open an old ripped movie i have on VHS tape.
There is the result of that film, 699 Mo:

Video=669Mo, 30FPS, 1,062Kbps, Resolution 640X480, XVID Mpeg4.
Audio=30 Mo, 48Kbps, 24,000Hz 2 Channels, 0X55=MpegLayer-3.

First, i execute Virtualdub and open that film.
I put audio to direct film copy and video to full processing mode and use
XVID codec to 1,050Kbps.
After i open the filter>Video filter>Neat Video. The video scan type is
on Progressive. The window open, (Neat Video Configuration).
I click on Configure...Click on Noise filter settings.
To the right at Filter preset, i choose Remove all noise,
click on apply and then click OK.

Now i'm ready to start, i click on File>Save as Avi.
The process start...I let it run over sixteen minutes after that i close
because it takes too much times...About 20 Hours ???

Do you think it's normal ?
That problem come from my computer ?:
Pentium-IV 2.4Ghz, 1Go Ram, WinXPPro.

Can you reply me please.
Thanks in advance.

It may be normal for that hardware. How long is the video in seconds?

Hi,
If i can't use Neat Video, because my computer is incompatible,
Would you have another good filter working with Virtualdub, or
another good software ?

Thanks a lot.

I don't think it is incompatible. NV runs on it, so it is compatible. It is just not the most recent hardware so it is not very fast. I think it is normal for that processor to spend about 20 hours processing this video clip in NV. I think it makes sense to simply let do the work. Looking for another solution may take more that 20 hours, because NV is very good in terms of noise reduction quality and while you can find some quicker filters, their results will not be as good.

Hope this helps,
Vlad

derac, it looks like you want to denoise and then directly encode to xvid. Denoising is very processor intense, and so is xvid encode.

I'd recommend rendering the denoised video first to a digital intermediate (Huffyuv, Lagarith or uncompressed), and use that to encode the Xvid. That way, you can do a two-pass encode as well, which will surely be looking nicer.

Also, be aware that you first need to generate a noise profile for your given source.
