From your view code i can see that you do not bind any model property named VideoPath or file so model can't bind your property value. As you declare file property so you need to bind this property to view like below

 @Html.TextBoxFor(model => model.File, new {@class = "form-control", @type = "file"})

Then you will get a file object to your model, Declare property like below

private HttpPostedFileBase _file;

    [DataType(DataType.Upload)]
    public HttpPostedFileBase File
    {
        get { return _file; }
        set { _file = value; }
    }

Then from controller

[HttpPost]

    public ActionResult SaveVideo(Video data)
    {
        try
        {
            if (ModelState.IsValid)
            {
                var uplodedFile = data.File;
             //you will get file path from this object property.
            //do other work here
         }
         catch(Exception e){throw;}
    }

If you have any query let us know.
