Blender Camera Tracking Help

I am facing a problem in camera tracking for my short film Kaijasti 2. I have basically shot with all characters though without a plain background. But i have markers and the camera was fixed to a tripod and never moved. I just need only the characters in front of the 3D model of a room and not the video background. I followed andrew price’s tutorial but that made the entire base video appear as background. Can anything be done?

If the camera never moves then there’s really no camera tracking to do. Sounds like you want to know how to separate your people from the background, but you didn’t use a green screen. That’s going to be difficult, if not impossible depending on how busy the background is. Can you post a still image from the video?
