Recorded a Mobile Phone Size Video Demo. Now I need more screen real estate

[New_guy1]

I recorded a video demo using an iPhone.

Very happy with the results. But now I want to add text boxes, OUTSIDE of my phone screen area.

My phone image is rectangular and in portrait mode. 

I would like to add text captions, arrows and other enhancements outside and to the RIGHT of this phone screen image How can I do this?
