I don’t want to be a smart-a** by asking an obvious question, but do you have either a Kona 3 card or a Io-HD? If so, the card will do the down-conversion in real time.

Well Forrest,
We’re going to get the Io-HD anyway. I’m going to hook up our M25U with the HDMI out going to the Io, and the machine control Firewire cable going to another PCI Firewire card.
And we’ll just see what happens.

The item is:
Ocean Matrix OMX-PSW6RS 6X1 RS422 Control Switcher

Markertek has a 6×1 passive switcher right now.

I’m leaning toward something simple like this. We have six different people using our edit suites, and some of these folks are “technically challenged.” I really thin they will get blown away if they have to patch audio, video, and machine control. I would rather they just press a button.

But, do you have another tape machine plugged into your Io-LA (like a Beta deck) that requires machine control?
Hopefully, the Io-HD will work like your LA. That answers my questions and solves my problems.

But even if it is on a different Firewire bus, I still think FCP will interpret it as two conflicting demands for serial information. The software is going to scream, “I’m confused. I’m just going to quit, and go home.”
I’m like you…that HVR-1500 is starting to look tempting. At least it has RS422 machine control. I can buy a cheap RS422 switch/router from Markertek that will switch from BetaSP to HDV to XDCAM-HD at the touch of a button, depending on which machine I need to control at the time. Plus, it would allow us to easily master back to HDV tape if/when we need to.

Forrest,
You’ve had the same idea that I had…connect a HDV deck to the Io-HD via the HDMI connections. But how do I provide machine control?
Gary Adcock wrote the following on another thread:
The IoHD uses the serial protocol over FW and delivers that serial control via the 9pin or LTC ports – having more than one device like that on your computer is not a good idea, as FCP is NOT smart enough to deal with 2 conflicting serial controls functions over the 2 different FW connections
Blame the FW protocols for the inconvenience, ALL devices that can control via serial over FW need take over the entire FW bus when working in SD and now in addition to the serial control we are also talking about the larger file sizes HD content, People are going to have to change how you work.
I know I can input/output video/audio and provide machine control to a BetaSP deck through the Io-HD. But, coming from a Sony M25U HDV deck, can I input the video/audio through the Io-HD HDMI connections, while providing machine control directly to the Mac through a separate Firewire cable? Based on what Gary said above, I cannot.
Are there any other ways to provide machine control to the HDV deck?

REPLY – you can use the firewire port to control this VTR. I have only seen the Y Pb Pr component signal from the HVR-M25U used with firewire control, I have never seen anyone use the HDMI port AND the firewire port at the same time. I have no idea of what will happen, or if the AJA will allow you to select this combination.
Bob,
This contradicts what I’ve been reading on other posts. If I provide machine control to the M25U through a Firewire port, doesn’t that mean I will have two different sources (the Io-HD and the M25U) that are asking the Mac for serial machine control information t the same time? Other posts have clearly stated the the Mac is not intelligent enough to sort all of this out.

Borjis,
We want to go with the full-blown deck. Some of that is because we’ve got some old thinkers around that cannot imagine life without a deck. But I also figure that there will be times that having HD-SDI i/o will be nice. I’m wondering if we can input the XDCAM via iLink, but dump the finished edit back to XDCAM disk via HD-SDI. That should save us the sometimes-long “conform” render.

Thanks Gary. I believe you’re right….the $75 will be well spent.
