I'm sorry to say that Poser has a rather steep learning curve, and I doubt very much that you will learn enough in a day to do a video.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
