One thing that sometimes went wrong with the synchronisation is which
fields it synchronized with (it would de-interlace by recording 2 tv
fields onto one film frame (I hope I got the terminology right here)).
For signal that originated from a tv camera it would't matter too much,
I imagine, you would possibly see interlace comb effects in either
synchronisation. But if the signal was originally filmed, you could get
fields from two originally different frames and then you would get
interlace comb effects where there were none before.
