How do I upload a video or FB live videos to my landing page?

The landing page can only accommodate Youtube videos or Vimeo videos, but you can download your FB Live video and upload it to your Youtube account, which means you can then link it to your landing page that way.

Just copy and paste the link to your video in the field for videos on your landing page. This can be a Youtube video (e.g. https://www.youtube.com/watch?v=V1XtxhkEuwc) or a Vimeo video (e.g. https://vimeo.com/399853676)

You can just follow these steps to download your FB Live video…
