FlipFlop is a small, free Mac OS X application designed to assist filmmakers with on set monitoring/previewing using a laptop and a firewire connected camera. The features came mostly from reading many peoples requests on various forums such as DVXUser and Redrock Micro.
Wicked cool! I'm all excited about ScopeBox, but FlipFlop is free and available now, which are two of my favorite software features.
The importance of full-resolution monitoring and scopes is something I cover in The Guide.
