Video Filter

You may insert videos from popular video sites by using a simple tag [video:URL].

Examples:

• Single video:
  [video:http://www.youtube.com/watch?v=uN1qUeId]
• Random video out of multiple:
  [video:http://www.youtube.com/watch?v=uN1qUeId1,http://www.youtube.com/watch?v=uN1qUeId2]
• Override default autoplay setting: [video:http://www.youtube.com/watch?v=uN1qUeId autoplay:1]
• Override default width and height:
  [video:http://www.youtube.com/watch?v=uN1qUeId width:X height:Y]
• Align the video:
  [video:http://www.youtube.com/watch?v=uN1qUeId align:right]
