notes: |
       The watermark filter combines a frame producer and a composite transition to overlay the specified text or image onto the video. Supplying a filename with extension ".txt" causes the loader to load a pango producer. Supplying a file name with an extension supported by gtk-pixbuf causes the loader to load a pixbuf producer. See the pango and pixbuf producers for details.
       Note: If the filename begins with "+" the pango producer interprets the filename as pango text.
       Text Example: melt colour:red -filter watermark:"+First Line~Second Line.txt" composite.progressive=1 producer.align=centre composite.valign=c composite.halign=c
       Image Example: melt clip.dv -filter watermark:logo.png
