Upon rereading this thread, I see an error early on. I correct it, below.

Hahahaha... ANY motion compensation. ...Is there more than one?

Carl Eugen said that, too. How could the timestamps be wrong? I was using the test video ("MOVE" 
"TEXT") that you gave me. I proved that, for that video (which I assumed was perfect), ffmpeg 
recursion of the filter complex does not occur.


Correction: "recursion" was "traversal" in the original posting. Sorry.
