Black Sync FCP to Beta SP
on Dec 4, 2009 at 5:53:24 pm

1st off...not real happy about having to use BetaSP in the 1st place but the studio that broadcasts a show we provide content for still plays the entire show off beta. Same workflow for the past 15 years...with out ONE upgrade...and yet they make a huge sum of money each season! Can't wait until I get to "Office Space" this deck! (Think...Slo-mo & baseball bats...hmmmmmm, get a smile just thinking about it)

Anyways, thats my rant, here is my question. We sent our BetaSP Deck (PVW-2800) out for a repair, error code 09, got it back and I seem to be having an issue holding sync after I reconnected the deck. I'm guessing this is operator error as the last time I connected it was over 2 years ago and everything had been working great then. The machine connected to the deck is a Mac Pro, with an AJA KonaLhe, we give it a ref signal with a BM mini converter sync generator.

Here is my problem. After we have layed video to tape, when we playback the tape we are getting some bumps and partial flips in the video for the 1st 3-5 seconds. We also have played other studios betaSP tapes & tapes that we layed off in our previous season in the deck and get a bump/flip for just the 1st second. It's there, but not as bad as our tapes we have recorded on the deck.

Please correct my setup where you see any issues:
1. I am sending the deck the Video through the componant out of the Kona

2. Giving the deck sync from the BM sync Gen to the Ref Video input with the Ω75 turned ON. Is this correct?

3. I have the Ref. IN of the Kona card connected to the BM sync gen.

4. On the BM sync gen I have the tabs set to what I think is NTSC. ALL 8 tabs UP? The graph on the back of the unit shows that 4-8 should be down in the OFF row. BUT on the actual tabs down is ON. I have tried it also with 4-8 in the ON position to match the look of the graph but still gets the same bumps & fliping effect.

The machine the deck is connected to:
Mac Pro 2.66 4core
FCP 6.0.6
AJA Kona Lhe

I appreciate any help, please forgive my ignorance with this giant dinosaur that takes up way to much room in the suite. Feel free to smirk, yell, & belittle...just follow it up with some suggestion. :)

Thanks again,

Dane

Open AJA Control Panel (you better know what this is, or I will beat your ass). Click on the Control Tab. Is it set for EXTERNAL REFERENCE or Free Run Internal ? If it ain't set to EXTERNAL REFERENCE, your wonderful Blackmagic Sync Gen is doing nothing, and you ain't genlocking anything to the PVW-2800.

And Mr. Dinosaur hater - let me assure you of one thing - you, I, and everyone else will have technical issues for the rest of your career. It's part of being in this business.

Thanks for the response. Yep, it's set Ext. Ref.

Hehehe, but being a dinosaur hater is a highlight of my day, the betaSP deck is just such an easy target for my frustration...granted my ignorance is likely the real culprit.

Thanks again for the suggestion,

you have given so little information on your project on your FCP system with the Kona LHe. Is it a SD project, or a HD project? Are you downconverting it ? Is it 23.98 or 59.94 or 29.97 ? If it is a simple NTSC 525 29.97 project, and you are playing it out to the PVW-2800, and you are getting "flips" - are you going analog component into this VTR (Y R-Y B-Y). Try doing a HARD RECORD (press play and record) instead of doing an "Edit to Tape" (which is an insert edit on the PVW-2800). If this works (no flips), and the Edit to Tape doesn't work, there is a problem with the insert ability of the PVW-2800. The 2800 is an old dog, and you just had it out for repair - who knows how good of a job this guy did .

Sorry about that, thought I had done a pretty good job outlining the issue. Obviously missed some key details!

SD project, NTSC 29.97, Video signal to deck is Analog component, Kona card seeing a 525i29.97 Ref. IN, BM sync generator to Ref. IN with Ω75 in ON position for termination

Bumps & jitters only for the 1st 3-5 seconds when playing from freshly recorded material from the tape. At no time does the video do a full flip, only bumps & jitters.

No bumps or jitters when monitoring the signal through the deck from FCP.

When recording to tape the video signal on Broadcast monitor holds still, no slight rolling or movement of the signal.

I'll try a "Hard Record" tomorrow morning to see if that has any different results.

Thanks again for the suggestions

the PVW2800 will let you do an insert edit right from the control panel. Just bring up color bars (don't even play out your sequence) and feed it into the 2800. Manually, have the 2800 do an insert edit. This will answer very quickly if you have a bad VTR.
