Transition of wave animation in css from left to right

Hi guys I am trying to make a wave animation in css by using an svg here, most of thing works fine but i do have one issue, once the waves reaches the end point, it starts over again all of a sudden and that difference is clearly visible, I want to make the transition smooth for better ui so that to user the wave seems to be endless.

Please check snippet below to understand my problem Thanks

.wave {
  background: url(https://gist.githubusercontent.com/ratnabh/da8213a27700e0e1c2d1c81961070f6f/raw/3608a5072f4e392b852e5cc3c244841025b32c81/wave1.svg) repeat-x; 
  position: absolute;
  opacity:0.2;
  bottom: 0px;
  width: 2000px;
  height: 198px;
  animation: wave 2s cubic-bezier( 0.36, 0.45, 0.63, 0.53) infinite;
  transform: translate3d(0, 0, 0);
}

@keyframes wave {
  0% {
    margin-left: 0;
  }
  100% {
    margin-left: -1000px;
  }
}

<div class="wave"></div>
