Adobe Captivate 4 has a feature using which you can access and control captivate movies from external movies. You can find more details here.

Here is how you access Adobe Captivate movie variables from external swf:

Action Script 3:
root.<variable_name>
Ex: root.rdinfoCurrentSlide, root.cpInfoAuthor

Action Script 2:
_root.<variable_name>
Ex: _root.rdinfoCurrentSlide, _root.cpInfoAuthor

Note : Few of the variables in Captivate AS2 movie are defined inside movie class. Hence cannot be accessed directly with _root. In these cases _root.movie.<variable_name> is the correct way to access variables defined inside rdmovie class. As a general rule, for AS2 to access a variable we should first try access it using _root.<variable_name>, if that comes undefined, then access using _root.movie.<variable_name>.

Variables that are defined inside the movie class are: cpInfoCurrentDateString, cpInfoCurrentDate, cpInfoCurrentMonth, cpInfoCurrentYear, cpInfoCurrentDay, cpInfoCurrentTime, cpInfoCurrentHour, cpInfoCurrentMinutes, cpInfoEpochMS, cpCmndVolume, cpInfoElapsedTimeMS, rdcmndGotoSlide, cpCmndGotoFrameAndResume, rdcmndNext, rdcmndPlaybarMoved, rdcmndMute, rdcmndCC, rdisMainMovie, cpInfoCurrentSlide, cpInfoCurrentSlideType
