What the IO does NOT do.
Ok, in case anyone is about to clone a tape with accurate timecode using the IO and the Control Panel, forget it. I’ve also confirmed this with AJA Tech Support today. Here was my scenario:
SDI SOURCE VIDEO –> IO
IO ANALOG COMPONANT –> BetaSPTC OUT to TC IN (deck to deck connection as there is no TC on the IO)
There is a 2 frame video delay that CANNOT be adjusted using the IO Control Panel. If you are shooting 24p footage, you will notice the problem right away (on the cloned tape) when you expect your A frames to fall on :00 or :05, instead they fall on :02 and :07 which is not correct.
Solution: Hooking the decks up directly, and bypassing the IO alltogether.
What a bummer as I expected the IO to handle something as simple as a clone. If anyone has another workaround using the IO, please let me know.

Well, it won’t wash your dirty dishes either. Your problem makes sense. If you were going through any a/d conversion you would experience this same delay. What you need is a time code processor from something like a Horita (TCP-50 is the model number). It’s a box that would insert a 2 frame delay into your timecode stream.

Thanks Jeremy for that product info. I didn’t know something like that existed. Now I might be able to continue to use my IO for Cloning tapes.
