Which device synchronizes a tape source to house sync to ensure that all cameras and recorders capture frames simultaneously?

A time-base corrector is essential in video production because it aligns the timing of video signals. When multiple cameras and recording devices are used, it is crucial that their playback is synchronized to maintain a consistent frame rate and to align the visual output. This synchronization is typically done using a house sync signal, which acts as a universal timing reference for all devices involved in the production.

The time-base corrector not only helps in synchronizing video sources but also corrects any timing errors that might occur during the recording or playback process, ensuring that frames are captured and displayed in sync across different devices. This function is vital in live productions or multi-camera setups, where visual consistency is key.

In contrast, a switcher is primarily used for selecting and switching between different video sources, while a signal amplifier boosts signal strength but does not address timing or synchronization issues. A digital recorder serves to store video content but does not synchronously manage the timing of feeds from multiple sources. Thus, the time-base corrector is the most appropriate device for ensuring synchronization of tape sources to house sync.
