I believe you can also adjust the production frame size by going into the render room and specifying the intended resolution for the final image. A couple of days I go I rendered some "widescreen" video -- when I changed the image output size from the default setting (640x480) to 350x100, this change was reflected in the PF in the assemble room. This method is probably not as reliable as Chuck's suggestion, but it may be worth trying out. Todd
