PRODUCT - Adding a video in the product page
There are two ways to add a video in a product page.
In product's description
The first way is to add it as part of the product's description. In order to embed a video that is responsive, pleaser refer to the official Shopify documentation.
In image slideshow
The second way is to add it directly in the product's slideshow.

Open the video of your choice in Vimeo, and click in the small plane icon (if you don't find the icon, this means that the video's author has disabled sharing, and you won't be able to add this video):
The link that you need to copy and set as the ALT text is outlined below in red:
