The name of the command is now "-loop 1" and contrary to before, it 
will now fail if it does not work (which I very much consider an 
improvement), so it's ffmpeg -loop 1 -i pngs/svg_tide.png.

"-I" is not supported by current versions, was it truly supported before?
(It's "-i" now)

Did you perhaps mean "-r 30000/1001"?
