Basic Definition:

What is FIZ (Focus, Iris, Zoom) in virtual production?


FIZ (Focus, Iris, Zoom) is a control system that allows remote adjustment of the focus, iris and zoom settings on a camera lens. This system has become increasingly important in virtual production as it offers efficient ways to fine-tune camera parameters without having to move the physical cameras. FIZ systems can be controlled by hardware such as lenses or rods with joysticks attached to them, or software programs running on tablets and phones. 

Controlling FIZ can significantly improve the workflow during virtual production. By having precise control over focus, iris, and zoom settings, filmmakers have greater freedom when making creative decisions while still adhering to the requirements of any given shot. In addition, using FIZ systems also eliminates the need for extra crew members who might otherwise be responsible for manually adjusting these parameters. 

When setting up a FIZ system, some best practices should be followed in order to ensure maximum efficiency. Firstly, all cables should be neatly labeled, making them easily identified when needed. Secondly, calibrating and checking the accuracy of each joystick should be done regularly to avoid latency issues. Thirdly, automated checks should ensure that settings remain consistent between shots. Finally, experienced operators should always be chosen to minimize errors and maximize results. 

FIZ (Focus, Iris, Zoom) systems offer incredible flexibility and convenience for those involved in virtual productions. They enable filmmakers to quickly adjust camera parameters with minimal effort, allowing them to take full advantage of their creativity while streamlining their workflow simultaneously.
