Hello Fred,
If you are just using one camera and the 744 there is no need for tri-
level or "beginning of frame genlock." If I can, I hard wire or send
continous tc. If I am in a situation jam syncing from a camera's
clock, I just make sure to re jam about every ten minutes.
The use of tri level or "HD genlock" in multi camera shoots is a
different issue and there is still no standard practice in that arena.

These issues illustrate the need for upfront communication on
workflow. If you have not, Check out Wolf Seeburg's books
