wish help you to fix your issue While checking with media element the duration is getting only after the media opened event. , getting duration of video file in Win Rt App or Metro C#

will help you 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.

code :

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';
  }
}

<div id="input-upload-file" class="box-shadow">
  <span>upload! (ღ˘⌣˘ღ)</span>
  <input type="file" class="upload" id="fileUp" name="fileUpload">
</div>
<pre id="infos"></pre>

How to get duration of video when I am using filereader to read the video file?

will help you You can do something like this for that to work:
read the file as ArrayBuffer (this can be posted directly to server as a binary stream later) wrap it in a Blob object create an object URL for the blob and finally set the url as the video source.

code :

var fileEl = document.querySelector("input");
fileEl.onchange = function(e) {

  var file = e.target.files[0],                               // selected file
      mime = file.type,                                       // store mime for later
      rd = new FileReader();                                  // create a FileReader
  
  rd.onload = function(e) {                                   // when file has read:
    
    var blob = new Blob([e.target.result], {type: mime}),     // create a blob of buffer
        url = (URL || webkitURL).createObjectURL(blob),       // create o-URL of blob
        video = document.createElement("video");              // create video element

    video.preload = "metadata";                               // preload setting
    video.addEventListener("loadedmetadata", function() {     // when enough data loads
      document.querySelector("div")
          .innerHTML = "Duration: " + video.duration + "s";   // show duration
      (URL || webkitURL).revokeObjectURL(url);                // clean up

      // ... continue from here ...

    });
    video.src = url;                                          // start video load
  };
  rd.readAsArrayBuffer(file);                                 // read file object
};
