My code has something like shown below.

hold on
    for
   indices=1:length(tracking)
        box=tracking(indices).BoundingBox;
        plot(tracking(indices).Centroid(1),tracking(indices).Centroid(2),'y*');
        text(v3(:,1)+20,v3(:,2)-20,num2str(r),'Color','white');
        rectangle('position',box,'Edgecolor','red','LineWidth',2);
         end
  hold off

this hold on-hold off method wont let my video play at normal frame rate.

Please provide me a way to save these images back into another video ALONG WITH the plots,text on it. (hoping to use getframe somehow.)

Thanks in advance.
