user1161: We are looking to enhance our production with some lower thirds keying on our video.
We currently output a single HD stream and encode it in real time. This output doesn't have any keying because it's application requires it to NOT have this.
A new request that has come in is to have a separate recording that DOES have lower thirds keying for a couple of select applications.
We could add the keying in post production, however this is time consuming and we'd rather not.
I've attached a diagram of how our system is currently configured.
I'm wondering what the best way to add lower thirds keying would be if we're doing it in real time on a second stream... and is this possible with our current equipment list?


My thought on this would be to throw a Mac mini on the second preview output and use software to key the output of the Mac back into a second input card on the StreamZHD. 
I'm a little nervous in using the built in keying ability as it would require a single operator to be managing ALL of our production.

user221: Much like your Mac Mini approach, you can set up a PC with a free demo of vMix (http://www.vmix.com.au) and see if it will work for you.

user2773: I'd recommend to add an optional i/o board (AV-HS04M7 or AV-HS04M1 for external CG) to have simultaneous program output w/o graphics (clean feed) and still have fully functional preview & program outputs. You can use ProPresenter or any template-based CG with key&fill outputs, which is quite simple to control. E.g. CasparCG. You can even create a special control application for shows, an operator would have to push the only button at desired time.
