Genlock and sync explained practically

Why every source must tick to the same clock and how to make it happen.

Genlock gives every device a common reference clock (blackburst or tri-level sync) so pictures line up when you cut - without it you get a jump or glitch on the transition.

In practice

  • One sync generator, distributed to all devices.
  • Verify each device actually looks at the reference.
  • Cable lengths and termination matter.
