Connecting Sync Gen to HDCAM deck and Avid…help please

[Bob Zelin]

Bill –
I am trying to answer you on the AJA forum. Do you have an AVID or do you have an AJA I/O HD. Please tell me the rest of your gear – what is your edit system, and what is your TV monitor to watch the HD signal ?

Also please tell me which forum you want me to respond on .

I replied to you in the AJA forum.

Thanks

You need 1080/23.976sF tri-sync reference to do what you want. From the picture of the box, the Aja sync gen doesn’t appear to have a setting for that. We use Evertz HD sync generators in our edit rooms, and these units do have this setting, which does work well with both Avid and the HDW-500 VTR.

Bill has no idea of what he is talking about. I am well versed with the Evertz 7750 tri level sync generator, and so is AJA. The AJA GEN10 ABSOLUTELY provides for 23.976 tri level sync output. Read the f#$%ing .pdf Bill before talking. Your AVID and HDW-500 will work just fine at 59.94 as well, AND it will work with conventional black reference if you choose a 2:3 pulldown on the HDW-500. The AJA GEN10 provides any one of these. And of course, so does the Evertz 7750 card. And so does the Ensemble Design, the Astro Systems, the Tektronix, the Leader, the Sigma TSG490, and plenty of others. But the AJA GEN10 is $390 – about 1/10th the price of any other product on the market.

The Evertz 7750 has one main advantage to the AJA GEN10. It can be genlocked to an existing house generator, where the AJA GEN10 has no genlock capability. The DIP switch settings of the Evertz 7750 are just as confusing, if not more, than the AJA GEN10. (you set the tri level frame rate with switches 6, 7, and 8).

Correct answers for this appear in the AJA forum.

The most important difference that has been overlooked is that the Evertz and most other professional sync generators have independently time-able outputs. The AJA does not. That is the reason it is so cheap. It’s not genlockable so you couldn’t slave another one. This is fine if you are a 1 person shop with 1 deck and an avid. If you have the need for multiple sync outputs the AJA is not a viable option.
