. the most configurable option would be to write your own module to allow you to pick and choose which parameters from which layer would be applied to another layer...
. you can use the Modules->Keyword Browser (and the click the 'Pick In interface' button to determine the name of the element, like
. then to get the value :
mySpeed = modul8.getValue('ctrl_layer_movie_speedFactor', 0)
. 0 for currently active layer, or you can hardcode the layer if it will always be the same or create a UI element in your module to choose the 'from' and 'to' layers dynamically. the set the value:
modul8.setValue('ctrl_layer_movie_speedFactor', mySpeed, 2 )
. the '2' being layer 2 - but set that to the layer you want to change. check out the Modul8 online manual for more information about getting and setting values.
. good luck!
