"Error: There is no function named RemoveDirt" This is a typical error message when there is a missing plugin. What to do about it?
We go to the
Avisynth wiki, External Filters page and search it for the plugin "RemoveDirt."
Now we have a link to the
RemoveDirt web site; we go there, download the
file(s) and read the instructions.
We unzip the ZIP file and copy the file(s) (plugins files are usually *.dll or *.avsi) into the Avisynth "plugins" folder.
Then we try the script again. If it works, great; if we get another error, we repeat the process: search, install, retry.
