Shot in 4K this sparkle overlay can be used in a number of ways. As a background, compositing over footage, or as an overlay. It gives a nice rainbow / spectrum / crystal look. It was created by distorting light onto the exposed sensor through a crystal, no lens. It was made with real light, not CGI or plugins or effects, and was shot on the Blackmagic 4K production camera, captured and mastered in ProRes HQ 4K. My HD versions have been used in NatGeo and Discovery shows - these are now my new 4K versions How to use - composite over a wipe or dissolve using the 'add' or 'screen' layering technique.
