All content from YouTube works with Ghost automatically via our OEmbed integration. All you have to do is paste a URL!
When using videos in your content it's important to use reliable video hosting with great performance so that your readers are always able to play your content. Generally speaking, self-hosting videos is very hard to do reliably - so it's a much better idea to use a proper video provider and embed one of their players on your Ghost site.
Fortunately you'll find that Ghost is compatible with all of them, no matter which service you prefer! Here's a quick guide for YouTube:
Copy the URL of the video
Grab the URL of the video you'd like to embed into your post or page
Paste it into the Ghost editor
When you paste it into the Ghost editor it'll be automatically transformed into a rich embed of the video you selected
Publish your post
That's all there is to it! Ghost interacts with YouTube via their OEmbed API in order to retrieve all the correct settings automatically and serve your video in the best way possible.
Here's an example of the end result:
