Adding video field to product template

in every product i need to insert a video talking about the product but when i go to ecommerce product page i can just add description,photo…but i need to add a video field which contain the link

Have you tried embedding the video link in a rich text field? This should let you include videos in the product descriptions.

Another thing you can try is creating a custom URL field and using custom code to embed the video in your product template.

Hope this helps!
