Do you find your Video Thumbnail Size is too small? If so, follow this guide to increase the sizes of you video uploads’ thumbnails!

Open \application\modules\Video\controllers\IndexController.php file. Find these lines (start at line #970):

// handles thumbnails
  public function handleThumbnail($type, $code = null){
    switch ($type) {
      //youtube
      case "1":
        //http://img.youtube.com/vi/Y75eFjjgAEc/default.jpg
        return "http://img.youtube.com/vi/$code/default.jpg";
      //vimeo
      case "2":
        //thumbnail_medium
        $data = simplexml_load_file("http://vimeo.com/api/v2/video/".$code.".xml");
        $thumbnail = $data->video->thumbnail_medium;
        return $thumbnail;
    }  
  }

Replace them with these lines:

// handles thumbnails
  public function handleThumbnail($type, $code = null){
    switch ($type) {
      //youtube
      case "1":
        //http://img.youtube.com/vi/Y75eFjjgAEc/default.jpg
        //return "http://img.youtube.com/vi/$code/default.jpg";
        return "http://img.youtube.com/vi/$code/0.jpg";
      //vimeo
      case "2":
        //thumbnail_medium
        $data = simplexml_load_file("http://vimeo.com/api/v2/video/".$code.".xml");
        $thumbnail = $data->video->thumbnail_medium;
        return $thumbnail;
    }  
  }

Now you will get 480x360px thumbnail from Youtube instead of 120x90px. After this, you need to change the size of image which is saved on your system. Find line #241 in the same file. It should look like this:

$image->open($tmp_file)
          ->resize(256, 192)
          ->write($thumb_file)
          ->destroy();

Replace the 256, 192 with width and height you need for your thumbnail.
There is one more step. In the same file, find line #819:

$image->open($tmp_file)
          ->resize(256, 192)
          ->write($thumb_file)
          ->destroy();

It’s the same code as previous and you should put the same values as before for width and height.
