Hello,

I'm almost there in terms of achiving a good quality movie captured from a VHS source, and there is only one thing left that I need to know. At some point of my sample encoded clip, there is a noticeable artifacts or noise that are similar the sample picture shown in the MSmooth filter home page:

http://shelob.mordor.net/dgraft/

(Select MSmooth link under AVISynth filter).

For sure MSmooth filter or TMPGenc Noise Reduction can resolve this issue, but using this filter will increase the encoding time, and it's really very very slow....to give u an idea, using TMPGenc Noise Reduction filter will double my encoding time, while using MSmooth (my first attempt) using default value, I've got a total encoding time shown on TMPgenc to be 892 hours.

So my question is, is there anybody knows of an equivalent smoothing filter just like Msmooth, the will handle the artifacts that I am experiencing (please check the web site above for MSmooth) but will not greatly affect my encoding time, I'm basically looking for a very fast smoothing filter. Thus fluxsmooth, nomosmooth can fix the noise problem that I am getting?

And lastly, I am a newbie to this video editing thing, and don't exactly understand so much about video editing terms, being that said, can you possibly tell me in layman's term what exactly does fluxsmooth and nomosmooth do? The readme file for those filter is a little technical for me.

Appreciate any help.

Thanks,
Dredj

I use fluxsmooth but it's hard to tell if it fix the artifacts _you_ have. The best is that _you_ do the test, no ?

Hello Dialhot, r u using fluxsmooth with the default value (7,7) ? it seems to add 6 hours to my encoding time, so maybe I could lower the value. Also where exactly in optimal script this should be added? Right now I add it right after the MergeLuma(blur(0.1)) line...is this okay?

Thanks much...

For sure.

Do you use avs2.52 ? if not, go to it ! And if yes, try to add a "convertToYV12()" after the load of your source.

Why don't you just find in virtualdub the part of your video where you have the artifacts and use only a sample of the total video using the trim command ?

Seems correct.
