How do I Add a Video to a Blog Post?

There are two ways that you can add a Video to your blog post. 

When inserting your video it will have to be hosted on a sever - maybe an existing blog or website you control.
You will also need to know the dimensions in pixels of the video.

When adding an image using the Embed option you video will have to be hosted on a 3rd party site such as YouTube. You can get the embed code from the video sharing options on the YouTube video page. You will need to copy the embed code and then paste it into your blog post using your cursor to dictate the placement position
