Laying back 4:4:4 to a 4:2:2 tape

Hello everyone,

I've had a request from a client to make some 4:4:4 deliveries to HDCam-SR. This is the first time I've done a 4:4:4 delivery, and I was wondering if there's anyone here who could help me clear up a few things.

I'm using MC 6.0.1, a Mojo DX, and an SRW-5500. I know how to set up Avid and the Mojo for RGB 4:4:4, but we don't have the HKSR5003 option board that allows me to switch the SRW-5500 System Signal to 4:4:4. We also have a SRW-5800, but I believe it's a pre-2008 5800/1 model because again I have no control over the System Signal. We can't really afford a $13,000 processing board right now, so what I'm wondering is this:

If the Avid project and the Mojo are both set to 4:4:4, will the picture itself still be 4:4:4 if laid back to a 4:2:2 tape?

I'm still gathering information from the client, but from what I understand so far the tapes will be used for DVD authoring and not any kind of broadcast. We have done similar deliveries (HDSRs for DVD authoring) before, and I just checked our back-ups of those tapes and they're 4:2:2 as well.

If anyone can give me a bit of information in this so I can speak a little more confidently when I bring my boss some option, that would be amazing.

Thanks all so much,

Hi Shannon,
not sure what you mean when you say "...laid back to a 4:2:2 tape". All HDCAM-SR tapes are the same, there is no special 4:4:4 tape type.
You should be able to switch your SRW-5800 to 4:4:4 in the same set-up panel where you switch frame rates. If it isn't there then it not the /2 model.
In that case I doubt the deck would even see your 4:4:4 signal coming in at all.
I don't really see why your client absolutely needs 4:4:4 if it is indeed for DVD authoring. Maybe looking into this would be my first step before thinking about renting a /2 deck.

Also, unless your source material is 444 and you have captured and been editing in RGB 444 within Avid, then your footage is only 422 anyway.
