Recipe Schema: Video Attribute missing

Ran a recipe created with Cooked Pro through the Google Structured Data Testing Tool, and came back with one warning: The video field is recommended. Please provide a value if available.

This is despite having a video in the recipe’s gallery. Am I correct that this field is not supported with cooked, or am I doing something wrong? If it’snot supported, anyone know how to add it manually? I want to make sure my recipes get as much exposure with Google as possible.
