This tutorial is going to show you how to add or change a product video on your Magento store.
Log into your Magento admin panel.
Go to Catalog->Manage Products:
Click on the product you want to add a video to or which already has the video you’d like to change:
The General tab should be opened by default. Scroll down till you see the Video URL option:
Open the page at https://www.youtube.com with the video you want to add to the product.
Under the video there should be a Share button. Click on Embed and copy the link between src=””:
Paste it to the Video URL field of your product:
NOTE: Sometimes you will need to use //www.youtube.com/embed/3TTswKT9J9g instead of https://www.youtube.com/embed/3TTswKT9J9g due to SSL settings.
Click Save at the top right and refresh the product page to see the changes.
You may also need to clear the cache.
