Re: how to place label or scene graph element on video node
I am not sure what this is about. Videos are played on separate plane behind the graphics plane (where all UI elements are displayed, including RSG Group progeny). The video is always behind the graphics and sometimes you may have to do a cut-out/transparency in your overlay graphics for it to display.
If some UI element is not displaying, my suspicion is that another UI element is covering it, displayed on top of it. I would like to hear more about this translation="[1,0]" magic - if indeed a clean experiment says it makes a difference (i.e. change to [0,0] and confirm this alone makes the element disappear)
