Hi..Are you creating your own animations with puppeteering etc or are you using a stock motion clip included with CrazyTalk? If you are using puppeteering then you should be able to record animation over the full length of the project.
You can check the length of the script file (.CTS) by going to Script - Stage and checking that the CTS Length matches the Project Length (see below). You can also find out much more about creating scripts in CrazyTalk 6 HERE.
