Thanks for the input. Using Crazy Talk Standard.  Had to animate one side, then the other and then assemble the parts in iMovie.  How can I animate the eyes for both heads at the same time?  Open to suggestions.  Perhaps animate one side, put in listening mode for part of the time then talk other part of the time, same for the other side then run the clips together one under the other in iMovie?  Will try.  Otherwise I will try something else.

I am on the road so I may not be able to get back readily for a bit.  But thanks for the help in advance.

I think my first initial post describes how...

Cut your audio up into the different pieces of the conversation.  Import the first audio clip.  If it's the specific head's part of the conversation, lip synch it.  If it's not, use the Listening reaction.  Then import the next audio clip, if it's that head's turn to talk, lip synch it, if not use the Listening mode.  Do this until you're done.  (BTW, you may be able to do it with one clip, assuming that CT Standard allows you to switch between lip synch and listen mode on the fly.  I'm pretty sure the Pro version does. A single audio file would make the timing better and easier to deal with in post).  Export to video.  Do the 2nd head in a 2nd project the same way, just reversing when the head lip synchs and when he listens.  Export to video.

Load up in your video editor both clips. Use whatever masking magic your video editor provides to ensure both heads are visible on their own layers (or in the appropriate place in the frame), mute the video on both of them, and load in your audio into your editor to synch it up with the video.  Export out.

The key element while in CT is to record the same head for the duration of the entire conversation, regardless if they're talking or listening.  This way their eyes are the correct animated eyes for the duration of the clip.  Another benefit, the non-talking head can react to what the other head is saying, by nodding in agreement, winking, etc...  It will give it the impression that it's a singular clip, and the heads truly are conversiong together.

Thanks again Will try it out and let you know....
