Add a Video to an Amazon Listing

Hi –

I’m a freelance copy & content writer working on a blog post on this topic. I don’t have an Amazon seller account, and was wondering if anyone could access this Seller Central link to get the actual instructions on how to add a video to a product page. Any help appreciated, thanks!

Here is the link that I can’t access: https://sellercentral.amazon.com/seller-forums/discussions/t/b031f21d-e8e2-49ea-933c-bef293bf9427
