Trying to upload a video hosted on Vimeo to a post of mine so I can more accurately showcase the issue I'm having. When I use the "insert video" button I see the link inserted in my post, but when I save the post/edit there's nothing actually there.

Can someone help me understand the best way to upload a video within my post, either embedded or a hyperlink? If Vimeo isn't the best that's fine, I just chose it since it was the fastest way to get my video uploaded.

Thanks!
