Very similar video's being produced from very different descriptions

I have been experimenting and have found that I am getting very similar video productions from very different descriptions. This is wasting a lot of time (and money) in terms of using my credits. Can you assist? Please look at today's creations, and you will see what I mean.

Many thanks

Stuart

PS - I love the product, but am feeding it money at the moment and not getting the full results I am after....
