2. how can i add a condition that if the custom field with id 34 has any value then this tab and content should appear ?

Hi,

As it is a custom product field, the content is stored in the product PHP object.
The easiest way will be to use the check on the custom field column name.

So in the view, "product / show_tabular", in the video tab you can add code like:

<?php
echo $this->element->product_video; // if you named the video custom field "product_video"
?>

<?php
if(!empty($this->element->product_video)){
?>
<li>...</li>
<?php
}
?>

You are awesoooomeeee !
thanks !
