@FabianQuiroga is right that you should better use createObjectURL than a FileReader in this case, but your problem has more to do with the fact that you set the src of a <source> element, so you need to call videoElement.load().

$(document).on("change", ".file_multi_video", function(evt) {
  var $source = $('#video_here');
  $source[0].src = URL.createObjectURL(this.files[0]);
  $source.parent()[0].load();
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<video width="400" controls>
  <source src="mov_bbb.mp4" id="video_here">
    Your browser does not support HTML5 video.
</video>

<input type="file" name="file[]" class="file_multi_video" accept="video/*">

Ps: don't forget to call URL.revokeObjectURL($source[0].src) when you don't need it anymore.
