I've already reading one frame at a time and I know want to select a one region of interest on every frame. It should by selected by imrect but I dont know how to put it, on all frames. I done it on image already but having problem with this.

Do you want to specify the box on the first frame and then have all subsequent frames use that same box location? Or do you want to interactively specify the box on each and every frame?

That's different - that's "tracking". Search MATLAB Central for "Tracking" - there are lots of demos/examples plus lots in the File Exchange.
