Black Burst Workflow
Posted by Eddie Torre on May 25, 2005 at 3:45 pmOkay, I thought I had this down, but after a few recent posts and going back to the IO manual, I guess I’m a little confused…
Is this the right workflow for a Sony Beta UVW-1800?
Black Burst (output) —>Aja IO Ref Loop In—>Aja IO Ref Loop Out—>VTR / VIDEO INPUT / REF VIDEO IN (switched to on)—> 75 ohm terminator?

May 25, 2005 at 4:38 pmyour black burst generator has multiple black burst outputs on it. Send a seperate feed from each black output to the Genlock or Reference Input of EVERY device you own – AJA I/O Reference In, UVW 1800 Ref In. And use the 75 ohm term switch on the Beta 1800 to ON, and purchase a 75 ohm BNC terminator and stick this on the AJA I/O Ref Video Loop. And when you get your Kona 2, and your pro DV VTR, and your Digi Beta VTR, you take another black output of your black generator, and feed it into each REf Video input, and terminate.
You certainly can loop, but your black generator has multiple outputs, and there is no reason to loop from device to device.

May 25, 2005 at 9:04 pmOK. I’m still confused… I’m using a (brand new) Horita BG-50 black generator. The Horita’s VIDEO LOOP output is connected to the AJA iO LOOP input. I have a wire connected from the AJA iO Ref output to the Ref Video, the 75 ohm term switch on the Beta 1800 is ON and no terminator. I guess I have to buy one too… Or do I have to buy several terminators, one for each device (monitor, SVHS, DV VTR, etc)?
One more thing: when I switch the UVW 1800’s Video In to COMPOSITE I can see reference BUT the deck has to be switched to YRB in order to receibe any signal from the AJA. When it’s switched to YRB I have No Ref. What can I do?PS: Until a while ago I was using a DataVideo Bi-Directional Converter (YUV to DV & DV to YUV) with a composite sync. signal output, connected to the AJA iO Loop input. Actually the same connection mentioned above, no terminators, no wires to any other devices. It used to work just fine. It’s a sadness I cannot use it anymore

May 25, 2005 at 10:16 pmI did not even read your entire post – I stopped at the Horita BG-50. The BG-50 will NOT work – you need a Horita BSG-50. The BG-50 Genlocks to a video source (like a camera), and provides 6 black outputs. You purchased the wrong unit. You need the STAND ALONE black generator from Horita, which is the BSG-50.
You see the No Ref (it actually says Error -093 Non Std Ref) on your Beta 1800 VTR, because you are NOT FEEDING A REFERENCE into your Beta machine. The BG-50 can’t go this until you feed a composite video signal into it. You bought the wrong unit.
The Horita’s Video Loop output jack is for the following. You have a camera, and you have to lock a bunch of other equipment to this camera in the field. You buy the BG-50, and take the camera composite out and plug it into the Video Loop In of the Horita. You then take the Loop out (which is still the camera signal, and feed this into your monitor on the set. You now have 6 additional Black outputs that are now genlocked to this camera.
But you are not in this situation. You need a STAND ALONE black generator, which is the Horita BSG-50.

May 25, 2005 at 10:53 pmBob,
Those are VERY BAD news!!! Somebody is going to kill me because I recommended him to buy this unit!
Doble bad, since I bought 2 of them.
Are you absolutelly sure? I mean, I’ve checked the features of both teh BG-50 and the BSG-50 and I’m still trying to find more differences than the S in the name! I do not want ot doubt you, but please, can you explain me why the BSG is good and why the BG is not?
Is there a way to feed a composite signal into the BG? If so, it will cause any loss of quality, I supose… -

May 26, 2005 at 8:44 pmThat sucks. I just ordered two of them. I suppose I should have read the specs more carefully but when I see “black burst generator” I have a certain expectation. My bad, I guess.

May 27, 2005 at 12:25 amThis is copied from the Horita website – it’s as clear as a bell. Simply go to http://www.horita.com, and READ the damn descriptions of the products. Would you buy an AJA I/O LA to to HD, just because the I/O LA is cheaper than the Kona 2?

The BG-50 uses any RS-170A composite video input signal (required) to provide multiple outputs of blackburst and composite sync for genlocking larger video systems.
All outputs are derived from the composite video input signal (required), which can be from any source, including “off tape”.
6 BNC blackburst outputs

May 27, 2005 at 2:04 amBoyce:
Calling it a “Multiple Output Black Generator” is misleading. It’s really a Black Burst distributor. Can’t you return or exchange them? If not you can go back to earlier discussions of using the Io’s composite out as a reference source and the Horita unit as a DA. BTW Horita’s website says that “all HORITA products come with an unconditional 30-day money back guarantee.”Good Luck

May 27, 2005 at 10:24 amSorry to bother you again, I have one more question:
Will the Horita BG-50 work as a stand alone black generator with a Kona LS or with a Kona 2?
Thanks

May 27, 2005 at 10:56 amNo bother. The BG-50 cannot work as a BB generator in any situation because it is not a generator, but a distributor. It requires a seperate BB generator such as the BSG-50.
So the issue is the same for Kona as Io. Neither have a reference out, but you can use the composite out.

May 27, 2005 at 11:05 amHow can I use the Horita’s composite out? I mean: Do I have to change the video in switch of the UVW 1800 to “composite”? If I do that the iO’s signal disappears but I have numbers running in the deck’s screen… I hope B&H wants to accept the BGs back and change them with BSGs!
