What technique synchronizes a time code generator to another device's time code via a temporary connection?

• A. Head pop
• B. Gaffer
• C. Layback
• D. Jam synch

Answer: (D)

Timecode synchronization between devices is achieved through jam synchronization. This method temporarily connects a timecode source to the device that needs to follow the master, feeding the master’s clock into the slave so its timebase locks to the master. Once locked, the device can continue running in sync even after the connection is removed, preventing drift during crucial transfers or multi‑department workflows. This is different from head pop, which relates to handling physical film; layback, which is about transferring audio or video to a master, and gaffer, which is a lighting role. Jam synchronization is the technique used when you need a quick, reliable lock to a master timecode.
