  Googling around it at least brought me to http://pages.uoregon.edu/noeckel/PDFmovie.html This page at least describes some formats and with an example document with which I was able to create rendition actions. And even trigger the debug output I added here.
  But I was unable to get the rendition action to work (even without having it as a chained action) in Okular. The page open play works fine.
  
  Here is my try:

  No. From the PDF reference on movie actions:

  So there is a difference.
  
  To be honest, I think that Movie actions and Renditon actions are deprecated, don't fully work and are exotic. 
  The most common usecase appears to be to have the Annotations on page open etc, which works.
  So I think we can, with good conscience, skip the support for them in this new feature here.
