I'm basicly doing about the same thing only I use Premiere Elements.

If I want to have a moving background I import it into Poser as an AVI file, or add it in Premiere.

Often I just use a static background in Poser.  There are a lot of tricks you can use when you do this.

If you want your character to look like it's really in a static background, you can take forground elements of the image and crop down to them in Photoshop.

Make a transmap for them, and place them on a panel, in the foreground in Poser sizing and positioning them to cover  the same element in the background image.

Now your character can move behind elements of the image making it look as if your figure is really inside the photo.  

Some times I use a static image that is wider then the view, and move the static image across the screen, this will let your character walk in place and appear to be moving in front of the image.

The linked clip shows both of those elements, near the end the background stops moving and the figure which had been stationary starts and walks off screen.

You are only limited by your imagination, if you mess around with it you can do almost any kind of effect.

I've only been doing this for a short time and I'm having a blast.

I allways wanted to make movies, now I can.

If you shoot a mime, do you need a silencer?
