You come across apps that take something to another level and you have to say ... "WOW"! Collabracam just did that for me. This app has some amazing possibilities!
Directly from the Collabracam website, "CollabraCam provides a quick, easy and fun way to shoot and simultaneously edit video from multiple cameras on-the-fly using iPhones, iPod Touches and now iPad 2. CollabraCam's patent pending technology links iOS devices running the app over local Wi-Fi to create a video switching and communication control room with a simple, yet powerful, live video editing workflow previously only available to professionals.
You and your crew will produce exciting, dynamic videos with minimal post-production. As the director, you can view, record and edit from up to four live-streaming iOS cameras in real-time while also having the ability to silently cue the operators of standby or recording cameras to perform pan, track, dolly or tilt camera moves or request a high or low angle."
Here is a terrible example video and some screenshots.
Notice the ability to give directions to your camera people!
