I saw a discussion on licencing for other matters, but Avisynth acts as a frameserver and has a fully open public licence - there would not be a licence issue importing these scripts so this statement is confusing. Are you sure they were referring to licencing on this specific issue?
I even just did a search for Avisynth licence on this forum and it didn’t come up with anything in case I missed it.
EDIT: Found it, they were using different spelling of licence. But yes, reading that I am still confused - there should not be any licencing required for using the Avisynth script import.
