For me, in the 1980s early 90s, making funny movies with my friends, an Amiga equiped with a Genlock was always the holy grail of gear. However, back then Genlocks were always out of my price range.
Now everyone is getting rid of their genlocks for $35, etc. I can finally afford one! Tempting, but probably only for nostalgic reasons, I think.
So...is there any reason, in today's age of digital video, to purchase a Genlock? Does it still have its uses, or is it just a waste of money (i.e. I should just do all my video titling, effects overlays, etc. in a modern PC editing program)?
