24 frame and wireless video assist is used in New York to keep video in sync. Filming is not just taking pictures, it requires the syncing of video as well as audio and event computer graphics with time-codes so that you can change from one cameras point of view to another seamlessly. Wireless video assist came from the need for cameras mounted on vehicles and in places cords could not go to transmit visual as well as sound and telemetry information. Examples of the need for wireless video assist can be seen on vehicles being crashed and totally destroyed and the need to capture video up to the point of destruction.
