I rendered a still image and it looks totally different than in the preview screen.  When I rendered the same file as a movie, the movie looked  like the preview screen?  I'm brand new with Poser and 3d, can anybody help me understand how the render works?  I'm mainly making a video and trying to make the models/figures look as realistic as possible.  

I thought that when you make a video, the steps would be to set up the scene, the character, the props, maybe do some adjustments in the material room, set up your lighting, make a still render and then use the animation controls to create the frames for the video.  

I was thinking the still render would let you know what would be rendered for the movie also. I'm thinking I was wrong?
