adding product videos

Hello,

I am trying to add a Product Video Intro to my product listings, I am trying to accomplish this by going to Products, Choosing a specific product, then going to the images and videos tab and adding the video.
I entered in the url in the space provided and clicked the check mark next to the video I want to upload, then saved it.
Need help designing these best animation videos. Please help me out.

Any help will be appreciated.
Thank you.

Default installation of Opencart does not provide video uploads by default. You must be referring to an extension.
