mcabel,

I think you lack some vc++ ver, try with full ver
https://github.com/abbodi1406/vcredist
And fftw3 latest ver (faster than 3.3.5 homepage)

#stab5= Lanczos4Resize(stab2,W,H).sharpen(0.5)

Thanks, I commented this(and a few other things) and finally made it run! (noticeably sharper as well!)


The author, Fred, seems to have several results for comparison, so I'm not sure how to send one out for encoding purposes.

Also about this, I don't see a prefetch() in the script, do I have to add one (where?)

After source load and before final Prefetch().

Current AVS working example is like
GeneralConvolution(0, "
-1 -2 -2 -2 -1
-2 -2 -3 -2 -2
-2 -3 70 -3 -2
-2 -2 -3 -2 -2
-1 -2 -2 -2 -1", auto=true, luma=true, chroma=false)

This is a noobie mistake, attaching "attachments" like this can take forever, if ever, to be approved, so no one gets to see them.

You need to use a site like "Imgur" or similar to do this.

Ah I see, thanks letting me know!

Ill use paste bin for the code and imgur for the image:

PD: after my previous comment I read that to send a video for encode I can use "return result" at the end of the file, so I did.

The only thing I'm missing (I think) is where to add Prefetch() (what does that do? ) so I can do the GeneralConvolution.

I have to admit, I don't & won't use either MeGUI or AvsPmod !!!

I think that Prefetch() may have to be early in the script...

Google might be your best friend.

Good luck.

Just out of curiosity, could you upload a sample of the clip you're trying to "clean up" ??? (MediaFire or similar)

"megui (gui/encoder for avisynth) and the script renamed to .txt"

You can not use any gui - you can write scripts in any text editor (free windows Notepad) and run encoding with x26x command line (.bat file also designed in notepad) with .avs input and monitor script output in VirtualDub (x32 and x64 versions for different running environments). Also FAR file manager have text editor and some AVS script highlignt if required.

So typical full working script example is about

LoadPlugin("ffms2.dll")

FFmpegSource2("myfile.mp4")

GeneralConvolution(0, "
-1 -2 -2 -2 -1
-2 -2 -3 -2 -2
-2 -3 70 -3 -2
-2 -2 -3 -2 -2
-1 -2 -2 -2 -1", auto=true, luma=true, chroma=false)

Prefetch(N) # N is your threads number for best performance - typically number of real cores of CPU

It is all explained in the included helpfile: you must change the variable "result" like this:

result="result1"

Or result2, result3 and so on.

Prefetch works only in Avisynth+, it speeds up a script.

Set this at the begin of the script:

 SetFilterMTMode("DEFAULT_MT_MODE", 2)

And set this at the end of the script:

Prefetch(2)

But sometimes I get "out of memory" messages when loading this in VirtualDub so I do not use it any more.
