make css animation smoothly loop forever

Hi every body, I'm trying to make my css animation look snapier, I want it to loop forever and do so smoothly, last frame should look like first frame but right now, when the animation finishes, it SNAPS back to the original state. I want to use this effect form my custom slider.

Here is my code:

.move{animation: move 30s ease;
  -ms-animation: move 30s ease; 
  -webkit-animation: move 30s ease; 
  -moz-animation: move 30s ease;
}


@keyframes move {
  0%{
    -webkit-transform-origin: bottom top;
    -moz-transform-origin: bottom top;
    -ms-transform-origin: bottom top;
    -o-transform-origin: bottom top;
    transform-origin: bottom top;
    transform: scale(1.0);
    -ms-transform: scale(1.0);
    -webkit-transform: scale(1.0);
    -o-transform: scale(1.0);
    -moz-transform: scale(1.0);
  }

  100% {
    transform: scale(1.3);
    -ms-transform: scale(1.3);
    -webkit-transform: scale(1.3);
    -o-transform: scale(1.3);
    -moz-transform: scale(1.3);
  }
}
