Genlock is a term commonly used in audiovisual technology that refers to a device that synchronizes multiple video signals. The word is spelled as "dʒɛnlɑk", with the "g" being replaced by the "j" sound, "e" pronounced as "ɛ", and "o" as "ɑ". The "n" and "l" sounds are pronounced separately. This spelling derives from the phonetic transcription system known as the International Phonetic Alphabet (IPA), which is used to accurately represent the sounds of spoken languages.
Genlock, short for generator locking, is a process of synchronizing the output of two or more electronic devices or systems, mainly used in the field of video production and broadcasting. It refers to the technique of ensuring various video sources are synchronized by locking their internal timing signals to a common reference signal.
In video production, genlock is crucial when combining multiple video sources to avoid issues like flickering, tearing, or inconsistency in the final output. It allows editors or broadcasters to seamlessly switch between different video signals without any discrepancies.
Genlock typically uses a genlock generator or device to supply a stable reference signal, known as a sync signal, which acts as a timing source. This reference signal serves as the master clock that all connected devices lock onto for synchronization. It allows the receiving devices to align their video frames, scan lines, and other timing elements, ensuring a consistent and seamless display of video output.
Genlock is commonly used in applications where different video sources need to be combined or overlaid, such as in live broadcasts, video editing, special effects, or multi-camera setups. It ensures that all camera feeds, graphics, titles, and other elements align perfectly, preventing timing mismatches and maintaining the overall integrity and professionalism of the video production. Overall, genlock plays a vital role in the technical aspects of video production, ensuring smooth operation and synchronization of video signals across multiple devices or systems.
The word "genlock" is a portmanteau derived from "generate" and "lock". "Generate" refers to the process of creating a video signal, while "lock" denotes synchronization. Genlock, often short for "generator locking", is a technique used in video production to synchronize multiple video sources together.
