In modern browsers, You can use the URL API's URL.createObjectURL() with an non appended video element to load the content of your file.

var myVideos = [];

window.URL = window.URL || window.webkitURL;

document.getElementById('fileUp').onchange = setFileInfo;

function setFileInfo() {
  var files = this.files;
  myVideos.push(files[0]);
  var video = document.createElement('video');
  video.preload = 'metadata';

  video.onloadedmetadata = function() {
    window.URL.revokeObjectURL(video.src);
    var duration = video.duration;
    myVideos[myVideos.length - 1].duration = duration;
    updateInfos();
  }

  video.src = URL.createObjectURL(files[0]);;
}


function updateInfos() {
  var infos = document.getElementById('infos');
  infos.textContent = "";
  for (var i = 0; i < myVideos.length; i++) {
    infos.textContent += myVideos[i].name + " duration: " + myVideos[i].duration + '\n';
  }
}
