<Hah! good idea, but I *don't have a camera* ! Thanks anyway.

I was afraid that would be the case.  But sometimes a simple answer like
using a camera is easily forgotten/overlooked.

If you can find a sync generator chip, it wouldn't be hard to build one.
The sync generator chip that I have is no longer made, so I haven't looked
to see what is out there nowdays.  Maybe someone else on the net can
recommend the latest chip that is out there.  From there spec sheets can
be found to help build a circuit.

Thanks for the confidence.

You know, maybe I should put together a black level generator/switcher
and sell it.  The circuit would allow you to input video and audio from
a source and output black level until the stuff you wanted to record
started.  I have that problem all the time.  An interesting thought.
