function mov = halfmix(fname1,fname2)
video1=playvideo(fname1);
video2=playvideo(fname2);
[h1,w1,c1] = size(video1(1).cdata);
[h2,w2,c2] = size(video2(1).cdata);
if(h1~=h2 && w1~=w2)
    disp('dimension are not equal to')
    return;
end
framenumbers1 = size(video1,2);
framenumbers2 = size(video2,2);
if(framenumbers1>framenumbers2)
      mov = video2;
      for i=1:framenumbers2  
      mov(i).cdata(1:h2,:,:) = video2(i).cdata(1:h2,:,:);
      end
      else
      mov = video1;
      for i = 1:framenumbers2
      mov(i).cdata(1:h2,:,:) = video1(i).cdata(1:h2,:,:);
      end 
  end
  end

this is what i do to hear but finally check the function is correct it response error in my code that point "vediofile" is undefined variable or function plz help if anyone can?
