Horizontal hold not holding
Excuse me if this topic shows up twice, I put it in earlier today but it didn’t seem to take.
Last Thursday I was working along, about to make some Beta dubs of a spot which was due for Fedex that evening when outta nowhere my Kona LH starts sending a shaky BxW image to my monitor, and of course, to my Beta deck. I checked all my settings in FCP and Kona, all good, trashed both prefs a couple of times, restarted, checked my viewer and canvas windows, View, all frames, refresh devices, nothing worked. Three calls to AJA tech did not help.
In the process of doing all this, I re-connected all my cables, during which time one of the central pins on my component cables to my monitor broke off, (I was feeding the monitor component via the auxillary component output from my UVW 1800) so AJA suggested I feed the monitor from composite or S video, the later of which I did.
In a panic, I called Steve Wargo who’s studio is quite close to mine, and within an hour, I brought a QT movie to his place and he made me a Beta dub for Fox in Houston and I made Fedex by 3 minutes, so a HUGE kudo to Steve. Battle won, but not the War.
That night I took the whole system apart, re-seated all the cards including the Kona, and that (mostly) fixed the problem. Only now, I have an NTSC monitor image which is scrolling up and down at will. I connected the BB generator to it and selected the ext sync button on the front, but it’s not helping.
Any way to fix this?

I’m not really sure bout how ur patching works…I do patch my FCP using blackmagic decklink to the DigiBeta…and the only experience for me to see the video skipping downwards slowly is the setting on the beta deck
It is set to “Ref Video” …which should be set to “Input Video”
hope this helps.
good luck

Howie,
Nowhere on my UVW 1800 can I find a menu setting called “input video.” I have gone through the menu setups in the manual and machine all morning, and nothing seems to affect the horizontal hold. I’m stumped.

I’m not sure if this is what you are referring to, but all old professional broadcast decks, (1″ Sony BVH-2000’s, Betacams) have a floating/moving black sync bar (horizontal hold in your words??) during dubbing, the signal is fine during playback. This has freaked out many clients (and several video production newbies) if they were in my studio while I was outputting the final Masters to either Betacam or 1″ tape, but when viewing the actual playback off tape, they are of course very happy!

Yes, I agree.
On a UVW-1800, (if your playback source is not “locked to house sync”) you must MANUALLY re-plug and “loop” the incoming video THROUGH the “Ref. Video” input first, and then into the regular “Video” input. (Careful of the 75-ohm terminations.)
If you don’t, the “un-synced” input timing will cause the image to “roll down” on the monitor during the recording.
But it should look fine on PLAYBACK of that tape.(Make a quick test recording to make sure.)

Okay, that all makes sense, except that, before I got my Kona card I was using a Decklink SP, and doing that looping thing through the ref with the Y signal, but that did not work well with the Kona so I had to get a black burst generator. Understand that until now, all my setups gave me a steady monitor, only since my latest Kona breakdown and switching from component monitoring to S video did this start to happen.

I record “S” into my UWV-1800, but I feed the composite out (from the DV source) to the “Ref. Video” input at the same time.
If I don’t (or try to use “house burst” with the 1800 while feeding from my “independent” (not synced) DV output to the 1800, the picture “rolls down” during the dub.
