How do I add a product video to a WooCommerce store?

The honest framing is that this is a three-step flow and the Shopify one is a one-step flow, because the Shopify app is embedded in the admin and can attach files to a product directly. There is no equivalent plugin here. You upload a product photo, pick a mood, and download the finished MP4 and stills; putting them on the product is then a normal media upload that you do.

For a self-hosted store that is usually the trade people would have picked anyway. Running your own WooCommerce install means already managing your own media, and being careful about what gets installed next to it. Nitaris never asks for access to your site, and the exchange is a photo in and files out — which is also why there is nothing to uninstall or to break on a WordPress update.

What comes back is a plain MP4 with no audio track and no watermark on paid files, in vertical 9:16 and widescreen 16:9, plus stills in square, portrait and vertical. Whether your particular theme or gallery plugin plays a video inline is a question about your installation rather than about the file, and it is worth checking before you plan a listing around it. If it does not, the film is still what you run on social and in ads, which is where most of its views were going to happen.
