How to Post a Videos on the Forum?

I have created an image using mypaint and have recorded the process. How do I share it with the community on your forum?

Discourse (this forum software) knows hows to present certain kinds of link as embeds when you paste them in. If the link is in a paragraph by itself, it sometimes expands the link into something more.

If everything’s working OK, that should be linked or playable. I only see the video thumbnail when previewing, however.
