I'm just uploading the new one.
It is the lamest error I ever made, although there were a few.
transitionType = 'kenburns' has migrated over from Animatics as the default value, even though no such is implemented in Lucid.
There were so few changes I made in Lucid 2.3.1 it was hard to imagine how I could have screwed it. I had to compare the output files to find this bugger.
