Generate 4 demo videos

[chrisnagy]

Worked it out in the Trajectory option.. 07 <---

.. The Where in the File .py is the place to Edit length from 7 to what ever number for the
4 generated is way smother and straight.
Compared to Creating one Trajectory options. Unless messing with the Translate x,y,z option will help

I will try a few vids messing with that
