Well, there are a lot of Shopify apps that help you embed videos from YouTube, Vimeo, IGTV, and whatnot but a lot of them don’t have a feature where you can add videos of your own.
I was thinking of the same feature lately, I just shot a couple of product videos with a white backdrop and felt like it’s better to add these videos to my online store rather than social channels. The reason being, I wanted to create a sense of exclusivity when my visitor comes to my online store. I didn’t want them to see the same thing they saw on YouTube or Instagram.
But I was also wondering, what if adding videos to my online store will lower my page load speed? And reducing my online store’s loading speed is the last thing I would want to have.
There are a couple of apps that allow you to add videos of your own but they don’t have a feature that could help you with adding videos from channels like YouTube or Instagram.
And if you’re just starting out I am sure you wouldn’t want to have multiple apps just to add videos. 
After hunting for the app that could help me add videos and asking my friends for it, I came across Videowise. It simply allows you to add your own video on the product/landing page, it fetches videos from YouTube, Instagram, TikTok and other channels.
It’s quite simple to set up and allows you to add videos of your choice in just a few clicks. I am still on the FREE trial, but yeah this week I am planning to upgrade it to a paid version. I hope I don’t regret even a single penny spent on it lol.
