How do I use this noise factory script ?

When I try to use it I get this error:

Script error: Invalid arguments to function "width"

Plugins I used is MaskTools & AddGrain

What is your script?

[xbox360]

More Info is available here:

http://www.neuron2.net/board/viewtopic.php?t=720

Yes, I know the function originates from there, but what is your complete script?

[xbox360]

LoadPlugin("DGDecode.dll")
Loadlugin("MaskTools.dll")
Loadlugin("AddGrain.dll")
Import("noisefactory.avs)

Mpeg2Source("xxx.d2v")

[Boulder]

You need to place the Import line after the MPEG2Source line. That way the contents of the imported script will be applied to the source (since the script is not wrapped inside a function in the avs file).

Still not working, same eror !!!:devil:

[Boulder]

Post the complete script once again ;)

[xbox360]

Boulder YOU SUCK !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! :mad::mad::mad::mad::mad::mad::mad::mad::mad::mad:

[Boulder]

If I ask you to post the complete script that you tried to use, that is not the way to respond.

@xbox360: Please reconsider you attitude toward people who are trying to help you.
