[HttpPost]
        public virtual async Task<IActionResult> ProductVideoAdd(int productId, [Validate]
                         ProductVideoModel model)
        {
            if (!await _permissionService.AuthorizeAsync(StandardPermissionProvider.ManageProducts))
                return AccessDeniedView();
            if (productId == 0)
                throw new ArgumentException();

            //try to get a product with the specified id
            var product = await _productService.GetProductByIdAsync(productId)
                ?? throw new ArgumentException("No product found with the specified id");
        
             var videoUrl = model?.VideoUrl?.TrimStart('~');

            try
            {
                if (!string.IsNullOrEmpty(model.VideoUrl))
                {
                    await PingVideoUrlAsync(videoUrl);
                }
                else
                {
                    return Json(new
                    {
                        success = false,
                        error = $"{await _localizationService.GetResourceAsync("Embed video URL is Empty")}",
