Your demonstrations are acknowledged here Chris. Thankyou for your effort. I 
examined each of them twice with what tools I have on my computer.

Then I applied a little known sophisticated technological trick to them.

As the movies ended and the composite appeared before replaying, I placed an 
accurate mouse pointer at the point of diminishing ablation or minimal 
light. I saw no evidence on any of the movies that there was significant 
travel(if any at all) beyond this pointer of the meteor.

Doing the same thing with the Goliath movie and confirming with the 
composite of Goliath, there is clear and present evidence of travel or 
movement beyond the pointer and continuing well past the last movie frame.

Please excuse the levity, I am in good spirit today. :-)
