18. A video presentation production system as recited in claim 17 wherein said second video camera has a power cable separate from said HDMI cable.

19. A video presentation production system as recited in claim 1 wherein said confidence monitor is larger than, separate from, and not integrated with said first video camera.

20. A video presentation production system as recited in claim 1 wherein said confidence monitor is at least three times wider than a width of said first video camera.

21. A video presentation production system as recited in claim 1 wherein said displayed content does not include a wired or wireless connection to said video presentation server.

22. A video presentation production system as recited in claim 1 wherein said synchronized video presentation media stream includes an image of said presenter looking straight downward from said presenter video feed.

23. A video presentation production system as recited in claim 22 wherein said synchronized video presentation media stream includes concurrently said image of said presenter looking straight downward and an image of a portion of a hand of said presenter or an instrument held in said hand from said presentation video feed.

24. A video presentation production system as recited in claim 1 wherein said synchronized video presentation media stream includes concurrently an image of said presenter looking straight downward from said presenter video feed and an image of a portion of a hand of said presenter or an instrument held in said hand from said presentation video feed that is touching an object on, or writing on, annotating or pointing to, said displayed content.

25. A method for displaying a synchronized video presentation media stream, said method comprising:
