We support several embedded video players, however we recommend using Youtube or Vimeo. Adding a video to your post is easy, simply paste the video URL into the editor's visual view.
Other embedded video players may work if the video provider offers an iframe embed code, just add the provider's iframe embed code into the HTML view of Kinja's compose editor. If the player is supported it will be visible once you switch back to compose editor's visual view.
You can add video embedded video to a reply, however replies only support Youtube and Vimeo link embeds.
