css - 更流畅的CSS动画

我一直在努力使这一过程更加顺畅：

-webkit-animation: pulse 1.4s ease-out;
-moz-animation: pulse 1.4s ease-out;
animation: pulse 1.4s ease-out;
-webkit-animation-iteration-count: infinite;
-moz-animation-iteration-count: infinite;
animation-iteration-count: infinite;

如您所见，它看起来有点机器人化。
有人知道有没有JavaScript的方法吗？

最好，

您应该使宽松线性

html {
  background: #fff;
  overflow: hidden;
  font-family: Helvetica, Arial;
  font-weight: 600;
  font-size: 16px;
}

.live-cta {
  position: absolute;
  top: 45%;
  left: 50%;
  margin-left: -50px;
}

.live-icon {
  position: relative;
  width: 40px;
  height: 40px;
  float: left;
}

.live-text {
  position: relative;
  float: left;
  margin: 12px 0 0 0;
  color: #007aff;
}

.live-arrow {
  background-image: url("http://s18.postimg.org/u8099c1c5/live_arrow.png");
  background-size: 40px 40px;
  background-repeat: no-repeat;
  width: 40px;

  z-index: 3;
}

.live-pulse-min {

.live-pulse-max {
  border: 4px solid #007aff;
  background: transparent;
  -webkit-border-radius: 100px;
  -moz-border-radius: 100px;
  border-radius: 100px;
  height: 28px;
  width: 28px;
  position: absolute;

  left: 2px;
  -webkit-animation: pulse2 1.4s linear;
  -moz-animation: pulse2 1.4s linear;
  animation: pulse2 1.4s linear;
  -webkit-animation-iteration-count: infinite;
  -moz-animation-iteration-count: infinite;
  animation-iteration-count: infinite;
  z-index: 1;
  opacity: 0;
}

@-webkit-keyframes "pulse" {
 0% {
    -webkit-transform: scale(0);
    opacity: 0.0;
 }
 50% {
    -webkit-transform: scale(.5);
    opacity: 1;
 }
 100% {
    -webkit-transform: scale(1);
    opacity: 0.0;
 }
}

@-webkit-keyframes "pulse2" {
 0% {
    -webkit-transform: scale(0);
    opacity: 0.0;
 }
 50% {
    -webkit-transform: scale(.5);
    opacity: 1;
 }
 100% {
    -webkit-transform: scale(1);
    opacity: 0.0;
 }
}

<div class="live-cta">
  <div class="live-icon">
    <div class="live-arrow"></div>
    <div class="live-pulse-min"></div>
    <div class="live-pulse-max"></div>
