Thanks Kevin. There are other ports you could use. Perhaps graphicsMagick ( as I recall) The fork from ImageMagick. ( I think that was the name)
The saveMovie() command is just a wrapper for a sys call so I considered going that route, but given the grief I had with ImageMagick, I decided not to try. You appear to have had more success, so you might try graphicsmagick.
