Black & Code to CVR-75 via ioHD
Greetings, All
For some reason that I can’t figure out, when I try to black and code a blank @ 00:58:00;02, the deck starts TC at 01:00:00;00.
I’ve been through the ioHD manual, the FCP manual, and the manual for the deck. Nothing seems to work. Running the latest firmware in the ioHD, Final Cut is up to date, OS 10.5.6, 3.2 dual quad Xeon w/16GB RAM, PCIe FW800 for external storage…
The deck is an Ampex CVR-75 (re-branded Sony BVW-75) set for external/regen/freerun TC, ioHD is set to LTC Port on input, output set to use QT TC. Both units are connected to a Blackmagic Sync. RS422 is working famously.
Still trying to figure out a few wrinkles, but overall the system works great – except for this. Hoping it’s something simple…
Thanks for your time. :o)

You probably want preset and not freerun, correct?
Are you using the black and code button?

Hey Jeremy,
I’ve got 3 switches for TCG: Int/Ext, Preset/Regen, and Rec Run/Freerun. Then there’s the LTC/Auto/VITC (set to Auto), NDF/DF (set to DF), VITC On/Off (set to On), and the ID Preset On/Off (set to On). I’ve tried both preset and regen, and rec run & freerun. Not sure if I’ve tried all permutations of those two switches, though.
I am indeed using the black and code button. Trying to, anyway. 😀
Edit: Just tried it again using Preset and Rec Run with the same results. I did notice something new, however. I have the ioHD display set to show primary in and LTC – the ioHD is showing 01:00:00;00 after I kick off the black & code, but before the deck responds. Wonder if it’s an Aja issue?

Doug,
this is not an AJA issue. You preset the TC generator for a number you want to start at (using INTERNAL TC, PRESET), put black into the input of the VTR composite input, and hit PLAY AND RECORD (crash record). This is how you black a tape. TC should start at the # that you put into the Ampex 75 display.When you are ready to output your show (Edit to Tape), you tell it go do to a certain in point to layoff the show (00:58:30:00 for example), and the edit system with the RS422 port on the I/O HD will search for this time code # and start the show at the # you told it to. But the AJA does not put time code on the tape. The VTR does this, and you do this IN ADVANCE of your Digital Cut Edit to Tape.
Just look at the VTR. Forget the computer. On the 75, go to INTERNAL, PRESET. Put in a TC # – any TC number – not just the 00:58 you want (that starts at 1 hour). Put in 7 hours, just for the hell of it. Now, hit play and record. Does the 75 start recording code at 7 hours, or does it jump to 1 hour like before. If it does, you are not setting up your VTR correctly.

Thanks Bob – I changed the settings on the deck for the test to Internal-Preset-Record Run, and it started recording where I told it to. So if I leave everything as-is except to switch back to External TC, then FinalCut should be able to send whatever TC I tell it to when blacking the tape, no?

Bob obviously hasn’t found the BLACK AND CODE button of FCP. If he did, he would realize how STUPID he is and he will then take a BASEBALL BAT and start beating HIMSELF in the HEAD. He can then take extended recovery time as the amount of accumulated time that his clients calls with this question will add up to about a week. Enjoy the golfing, Bob.
Sorry Doug, that was for Bob, not you. Please don’t take it personal, it was a dig at Mr Zelin-
You don’t need external tc, you need internal tc. I know that seems confusing but on the black and code, FCP is simply setting up the preset for you instead of you going in to the deck and setting it and then the deck generates the tc. Make sense?
Are you saying you successfully got it to black and code? Now you simply enter in the starting tc and assemble edit in the ETT window.

WooHoo!! That was it. Setting to Internal TC is counter-intuitive to say the least, but now working as advertised. Thanks for that, Jeremy. And I don’t take anything personally on any forum… it’s hard to discern intent without having facial expressions and tone-of-voice, so thanks again Bob for the clear instruction on the manual procedure (frustration with nOObs notwithstanding). ;o)

Glad you’re up and running.
