A '''frame synchronizer''' is a device used in live [[live television]] production to [[Timebasetelevision correctionproduction|production]] to match the timing]] of an incoming [[video]] source to the timing of an existing video system. They are often used to "time in" consumer video equipment to a professional system but can be used to stabilize any video. The frame synchronizer essentially takes a picture of each [[Film frame|frame]] of incoming video and then immediately outputs it immediately with the correct synchronization signals to match an existing video system. A [[genlocgenlock]] inputsignal is required to provide a means offor video synchronizing with the house reference clock.
