Moving to 'How do I'.
The complicated thing is like with audio there isn't one video format that plays on all platforms. So you will have to dual-encode your video and figure out a way to play the right format depending on the platform.
Ashley yes i figured out, i noticed why some browsers won't use .ogg and .webm as standard video format, they would use .mp4 but not royalty-free.
The biggest problem are IE, Safari and mobiles won't support .ogg :/
Do you think would you able to fallback system?
