Input Ref Video Signal from AJA io to Sony Betacam UVW-1800
I am attempting, for the first time, to record video from my AJA io to a Sony Betacam UVW-1800, and I keep getting sync errors from the betacam.
I have read a number of previous posts regarding the issue of getting sync into a UVW-1800, and I’ve tried the work-arounds – such as taking the composite signal from the I/O and sending it to the Video Input of the UVW-1800 with a loop into Ref Video Input – but I’m still getting error of “Input a Ref Video Signal.” (Initially the beta deck was displaying Error 94 – not 93 – but now it is simply displaying the error mentioned previously.) I tried taking the Loop out of the AJA, into a Hortia BG-50 (and, yes, I know it doesn’t create its own blackburst, but both AJA and Horita told me that wouldn’t be necessary) and then taking the output into the betacam but it still doesn’t work… I am at a loss. I’ve read the UVW-1800 manual, my AJA manual, my Horita manual. There must be something quite simple that I have overlooked. Does anyone have any ideas? -

that’s a hortia BG-50 and not a bsg 50?

Yes, the BG-50. I was told I didn’t need the BSG-50.

Well, you were told wrong. The BSG-50 is a very simple black generator and works extremely well with that deck. That’s either here nor there as you don’t have it.
What you need to do is take the composite video out of the AJA and put in in the REF IN of the UVW1800 (not the video in) and then flip the termination switch on the Beta to on. That should get around the problem you are having. You might see some rolling on the screen, but the Beta will record and playback fine.

Thanks, Jeremy – that solved the problem. (Though I swear I tried every possible combination before posting, so I’m perplexed that I missed that.)
So now I’d like to ask your opinion on what to do with the BG-50… should I get rid of it? My partner wants to eventually add another UVW-1800 to our suite. Does that mean I need the BSG-50, or can I run the composite out of the AJA, into the BG-50 and then into both decks? I am confused as to how this works and why, and everything I’ve read has only confused me further. Your help is greatly appreciated. -
I think the BG 50 will work, it just needs to be set up properly. I would return it and get the BSG50 as there’s no fuss. Simply run an output to each of the decks/devices that have reference inputs. If you run out of outputs, simply loop it in and out of each other making sure to terminate at the end. The BSG50 is one of those pieces of gear that once it’s set up you rarely have to touch it and you’ll probably forget that it’s there but it’s necessary for a stable tape environment, especially with UVW1800s.

Leah –
for future reference, to temporarily work to output from the AJA into the UVW-1800, here is a quick trick – this is not a system solution – just a quick trick, so you don’t get the Error 093 NON Std Ref error. Feed YRB component out of the AJA into the YRB component input of the AJA. Take the composite out of the AJA and stick it into the VIDEO IN of the Beta 1800, take a short BNC loop cable, one end on the Vid In loop input on the Beta 1800, and the other end on the REF VID in on the Beta 1800 – so both inputs are getting the same signal from the composite output of the AJA box. Turn the 75 ohm term swtich on the Video In to OFF, and the switch on the Ref Vid In to ON. This is a TEMPORARY solution.The person who told you that the BG-50 would work is an IDIOT. They have no understanding of these products, or their application. This was an attempt to save 50 bucks, and have nothing but aggrivation for it. The applicaton of the BG-50 is if you are in the field, with many cameras that need to be genlocked together. You take one camera, stick it into the BG-50 input, and this will create a stable reference to feed the genlock inputs to the other cameras (and possibly a small switcher and VTR, so you can do a small shoot). This is NOT a black generator, and is not a substitute for a Horita BSG-50, or more expensive Black Generator.

Whoa Bob, really? What’s this going to do except give feedback?

oops – I am a moron !

Bob,
Are there any BB/SG units that you prefer over the Horita line? I prefer something rack-mountable and hight quality.
Thanks,
Robert

to my knowlege, the LEAST EXPENSIVE black generator other than the Horita is the
Sigma BSG-26N, which is under $400, and is FANTASTIC. It comes with 6 BNC outputs, is rock stable for AJA, Blackmagic and AVID applications, and has an optional rack mount, called the RMK-26, which is only 50 bucks. The Horita BSG-50 is also available in rack mount, as the Horita BSG-50RM. I have found the ESE black generators to be unsuitable for our applications. I know nothing about the BURST Electronics black generators, but they certainly are not rack mountable. I also have never used the VAC Industries Black generator for our applications, but they do have a rack mount for thier little brick.After that, all the black generators are EXPENSIVE. The new Kramer (Ocean Matrix) is over $1000, and the “pro” units from Tektronix, Leader, Leitch, etc. are EXPENSIVE (multi thousand dollar units). SO, the Sigma BSG-26N is the unit of choice in my opinion – but the Horita BSG-50 is sure popular.
