Can anyone help with Avisynth scripts ???

[thefox149]

I hate to sound like a whinger but can somebody PLLLEAASE help understand how to frameserve with the vdub filters ......aarrgghhh I have been mucking around with the script for about 2 hrs I am a newbie to avisynth but have been encoding capping and what not for sometime and have tried to aviod learning avisynth but as my knowledge has progressed the need for avisynth is apparent and it seems the weapon of choice for efficient and effective encodes

When I open or encode the generated AVS the picture is fine ...but no filter. I have tried the logo filter the unsharp filter but nothing...aarrgt HELP me

AVS file to be framesevered looks like this

import("C:\temp tracks\games\avisynth-1.0-beta3\vdfilters.avs")
AVISource("C:\temp tracks\movie\maurice.avi")


My vdfilters import script looks like this: I got this from the avisyth1.0 beta download and thought it might help...nothing happens...the setting I use should give a grainy picture with the white spacing between pixels .....

I have read around and I think this is right (although it's not workin)

File that is being frameserved

import("C:\vdub6.avs")
AVISource("C:\temp tracks\movie\mauricetestfile.avi")
ConvertToRGB32()
VD_UnsharpMask(1,5,160,30,0,0,0,0,false)
ConvertToYUY2()

the import file looks like this

It won't load i keep getting script errors......very fustrating...

Help me

There are two problems here.

Firstly there are too many values, you don't need the '1' at the start? you should only have (diameter, strength, threshold, top, bottom, left, right, interlace) - in your example this will be (5,160,30,0,0,0,0,false) which incidently are pretty harsh but you'll see that when you get it working.

Secondly it's just unfortunate that you chose this particular filter to trial - there is an error in the import file.

This part ...

function VD_UnsharpMask(clip clip, int "diameter", int "strength", int "threshold",
\ bool "interlaced", int "mask_top", int "mask_bottom", int "mask_left", int "mask_right")
{

Should read ...

function VD_UnsharpMask(clip clip, int "diameter", int "strength", int "threshold",
\ int "mask_top", int "mask_bottom", int "mask_left", int "mask_right", bool "interlaced")
{

.. for some reason the author put the interlace variable in the middle instead of at the end.

I have tested these corrections and they work fine.

I used harsh setting for practise ..so that I could see the effect of what I was trying to do....than you so much I was going insane I will let you know how I go as my other machine is encoding at the moment and this one isn't set up for it.....

Put your plugins into the Avisynth2\plugins subdirectory.
Maybe it depends on the used versions, but here (Avisynth 2.08 + Unsharp 1.3) the "interlace" parameter is the 5th one.

old = AVISource("h:\test.avi")
new = VD_UnsharpMask( old, 5, 150, 0, false, 0, 0, 0, 0,)
# new = compare(old, new) # optional for test purposes
# Return StackHorizontal(old, new) # optional for test purposes
Return new


There is also an Avisynth plugin, that you may want to try, warpsharp.dll.

old = AVISource("h:\test.avi")#.ConvertToYUY2
new = UnsharpMask(old,strength=64, radius=3, threshold=10)
# new = compare(old, new) # optional for test purposes
# Return StackHorizontal(old, new) # optional for test purposes
Return new

#Description of the function
# 1.Calculate the value that blur of luminance.
# 2.From the subtraction of the luminance and value of "Description of
# the function 1.", calculate ingredient of the blur.
# 3.From coefficient(strength) and ingredient of the blur, adds to luminance.
#Description of the value
#strength : strength
#radius : Range of blur process
#threshold : threshold
#Only the case is processed that absolute value of "ingredient of the blur" #is larger than threshold.

Check out http://nickyguides.digital-digest.com/synth-vdub.htm. It is a decent guide to using avisynth scripts.

thanks bunyip!!!! You have saved me from acquiring more grey hairs and to everybody else for helping
