Proper way to setup a frame sync.

Postby firewood218 » Mon Jan 28, 2008 10:19 pm

Hey guys,
I'm a student who works in Video Engineering Services here on my campus. What is the proper way to setup a frame sync. I know you need a scope, but is there any good liturature online showing the "correct" way of setting it up?
Thanks!

So you want to have one playback deck go through it and into another to record? Not part of a much larger system?

If so, simply connect the following, using one half of the TBC:
VTR-P [video out] >> TBC [video in]
TBC [video out] >> VTR-R [video in]
Blackburst [or some stable source like a camera] >> TBC [genlock] >> terminator [use a BNC-T to connect the terminator]

VTR-P [audio out] >> VTR-R [audio in]

If you are setting it up independent of any other system, I would attach the waveform monitor in-line after the TBC [with the loop out going to the recorder]; if you want to have sync hooked to the WFM, run the genlock out of the T- on the TBC into the WFM with the same length cable as the video from the TBC to the WFM, then attach the [75ohm] terminator on the genlock/sync loopout of the WFM
