Hi,
You could configure a page to be able to view this video.
For example, it could be a Joomla article page with a content tag for video display:
extensions.joomla.org/tags/video-players-gallery/
And around the video, you could use HikaShop content tags like so:
{hkshow bought="XX"}
tags for the display of the video in the Joomla article
{/hkshow}
where XX is the id of a product you've created in HikaShop.
That way, when someone access this article page, HikaShop will replace this tags and either remove everything inside if the current user didn't bought the product, or leave the content if he did.
You can read more about hkshow and hkhide content tags here:
