Has nobody noticed there's only HDMI video output ?
Not to worry, just buy the extra cost adaptor cable! Yours for $19.99.

that looks a lot like the Canon composite out harness and plug.
Pardon the interruption but I have to point out that by making a purchase via the GoPro links at the bottom of the screen you'll be generating a small commission for the sebsite.
Thanks!
