Everything works like a charm now
Also, does it change something if we save the main script as an AVSI file in the plugin directory and then make a final script in a classic way ?
Code:
AviSource("videofile.avi")
Duplicity2(mode=2, show=false, ShowBlk=false, OthSCD2=255, IthSCD2=255, FillDrops=3, IBlend=false)
