Time Base Corrector vs. Frame Synchronizer

If you've ever wondered what the difference is between a Time Base Corrector (TBC) and a Frame Synchronizer, here's an example video.

Unlike the signal from a DVD, VHS tapes (and others) have unstable synchronization pulses. Normally the input circuit of your TV compensates for this, so the picture looks relatively stable.

If you're trying to capture the video to your PC or DVD recorder, though, you may run into issues with dropped frames or an unstable picture because the synchronization circuit quality varies between devices. Inserting a TBC between the player and digitizer may help or hurt depending on which has the better sync circuit.

For this video a DPS-575 studio quality TBC/synchronizer was utilized. I switched between synchronize only mode (TBC function disabled), and full TBC mode, which shifts each scan line back to where it thinks the line should be in reference to a stable horizontal sync signal.
