What is Genlock in virtual production?

Genlock is a technique used to synchronize the signals coming out of different sources, such as signal generators or similar sources. It works by matching the frames and subframes between these different sources so that they stay in sync with each other. This technique is essential for virtual productions working at higher frame rates, especially when performance capture is involved.

In order to create the highest quality images possible, all of the components of a virtual production need to be perfectly synchronized. That’s where genlock comes into play. When employed correctly, it can help achieve seamless transitions between shots without any image stutter or lag time. By ensuring all elements line up perfectly and stay in sync, you can avoid any errors that could cause discrepancies during playback. 

A typical example of using genlock would involve taking footage from multiple cameras connected via their respective signal cables. By enabling genlock on all the devices, one can ensure that each shot will appear perfectly synchronized across the board - allowing for precise editing during post-production. Additionally, by having proper control over the timing settings on all of your equipment, you can ensure everything lines up precisely so that even small details like motion blur won't be affected. 

The importance of genlock in virtual production cannot be understated. It allows filmmakers to take full advantage of modern technology while ensuring their shots are always perfectly timed and synced. Without genlock, achieving consistency throughout your project can become a real challenge, and mistakes can quickly occur.
