Find category for theme page

I am trying to find the category name. For other custom post types ( Woocommerse ) I do this, then use the id.

global $post;
$post_id = $post->ID;
$term_list = wp_get_post_terms($post_id,’product_cat’,array(‘fields’=>’ids’));
$cat_id = (int)$term_list[0];

For videos, i need the term to replace ‘product_cat’
