AJA Kona 3 - Mac Pro - PAL Land
on Sep 23, 2007 at 3:37:09 pm

I have a Kona3 card and have been having nothing but problems with it.

AJA have sent a replacement card as well as a replacement cable, I've even replaced the Mac Pro and still issues persist.

Just wanting to hear if anyone is using Kona3 in PAL connected to a PAL Digibeta and M2000 HD deck. Monitoring via HDLink to a LCD.

I'm getting sparkles on the HDLink monitor with it consistently dropping the signal. I also get a frame swopping issue from the Kona3 reference loop.

After weeks of trouble and many isolation sessions, swopping this for that then that for this to find the problem the only thing it points to is the Kona3 is bad so I need to get a Decklink.

Seems odd with AJA being connected to Apple and there Kona3 card not working like this in PAL land.

AJA are being cool with tech support although they don't have a PAL setup to test so they are working in the dark - crazy!

I have never used the Kona 3 in a PAL enviornment, but I use the Kona 3 with HDW-M2000 and DVW-A500 and DVW-M2000 on a regular basis in NTSC, with no issues.

Because you have changed everything, and are still getting "sparklies" in the video image, I suggest that you DO try the Blackmagic Decklink. I suspect that you will get the same problems, but you will feel much better after trying the Blackmagic, and seeing if you have the same problems (I bet you will).

As to what is causing your problem - I dont know. You say that you have changed the Kona 3, the MAC Pro, and have the problem with both Digi Beta AND HDW-M2000 ! The only thing left in common is your Blackmagic HD-Link which is how you monitor your video. Before I blame the HD-Link, perhaps you SHOULD try a Blackmagic Decklink card (like the Decklink HD Extreme) - this will answer your question very quickly if the problem is your AJA card or not.

Hi Bob

I don't think its the HDLink as it gets a solid signal when I feed it HD or SD directly from the VTR's and its only when the Kona3 is connected I get the sparkles and drop outs.

I would say this is a software problem with Kona3 drivers although AJA are saying its not but don't have PAL equipment to test it so they are shooting in the dark on this one and as I have the PAL equipment and have done the testing for them its extremely frustrating to be jumping through hoops.

Hopefully other Kona3 PAL users will speak up as I do find it incredible that there are so few PAL users out there.

I use a Kona LHe and I guess the drivers for that card are not very different to the drivers for the Kona 3 as far as the PAL signal is concerned. I have no problems at all with it

We edit a documentary series in 1080i/50 PAL and have never seen what you are describing. We do not use an HD link, but rather feed the Component and HD-SDI signals directly from the Kona 3's to our HD monitors and decks. We have never seen this "sparkle" behavior you're describing. If it was there, we would have noticed it and surely network quality control would have rejected the episodes.

I would look at the HD Link as a culprit. In your original post you said you're getting the sparkles through the HD Link but you didn't mention the decks. Are you NOT seeing the sparkles on the direct feeds from the Kona 3 to the VTRs? If not, then the Kona 3 is not the issue. Feed the HD Signal directly to the HD monitor and see if the sparkles are there.

If AJA has already sent you multiple replacement boards, then I really don't think it's the AJA boards.

Hi Rory -
I have read your reply, as well as everyone elses. If you have the luxury of being able to borrow a Blackmagic Decklink card (without having to pay for it), I would absolutely do it ! I personally believe that you will see the same problem (which is why you should not return the AJA hardware and purchase Blackmagic cards), but if you can try it, it will give you peace of mind. Sony VTR's will have "sparklies" when the scanners are dirty from the copper brushes "flaking off". I too think that this may be a Sony VTR issue, but I know that you are doing comprehensive tests. If you can get the Blackmagic card just for a test (and you are willing to do it ) - then try it.

[Rory Hinds] "I'm getting sparkles on the HDLink monitor with it consistently dropping the signal"

with the Kona crads swapped out- why is this not a decklink issue then? have you checked on any other type of display?

"After weeks of trouble and many isolation sessions, swopping this for that then that for this to find the problem the only thing it points to is the Kona3 is bad so I need to get a Decklink.

Rory
if you have swapped out cards and the problems still persist what makes you think it is not your system? the odds of 2 or more cards showing the same issue are remote.

have you checked the 2000 deck for issues also?

Hi Gary

I swopped out the Mac Pro so I know its not the Mac.

View a direct feed off the VRT via the HDLink is fine, its only when connected to the Kona3 that I have issues.

I've checked the Kona Control Panel and all is okay there.

I plan to purchase a Decklink card to rid me off this problem as everything is pointing to the Kona3.

I've replaced every component in my setup and still the problem persists with the Kona3... what more am I do to without tech support having the same setup as I do?

Sparkles sounds to me like a reference issue. Are you feeding solid reference to both the deck and the Kona card? Is the Kona card set to external reference?

Hi Terence

You are the voice of reason as I've been saying to support that this is a reference issue all along as the signal drops and I do get weird line alternating problems and now the sparkles.

I have tried setting the Kona3 to reference in to my Black&Burst and still no joy.

okay I'm convinced this is a ref sync issue.

I'm managed to get a stable signal with no sparkles in PAL SD as I have a Black and Burst going ref into the Kona3.

So this leaves HD to be sorted.

Do I have to purchase a TriSync for HD reference as the Kona3 doesn't work on Freerun?
This doesn't seem right as surely AJA would have mentioned this.

I don't have trisync on my systems. Just a standard Horita BSG-50 and we don't have the sparkles. You can pick up a Gen 10 from AJA though very inexpensively which is trilevel.

Hi Walter

Yeah I'm looking at getting the AJA trisync as it seems the only way to fix this.

Well actually I've just bought a Decklink HD Pro card which I'm sure will solve the problem as this is a software issue for sure.

I have no doubt your not having problems with NTSC or 30/60 in HD as this seems to be a 25i / 50i so will only effect the PAL world.

Will keep you posted on my progress or lack of it :-)

Like I said in my first post, we edit an international series in 1080i/50 PAL and have zero issues with that show. We've delivered 6 episodes so far and we've never seen any problems related to the frame rate, frame size or PAL in general.

REPLY -
perhaps I misinterpreted what was going on here, and I am SO confused by all the posts. I was under the foolish impression from the above sentence that you DO have a PAL Black signal going into your Digi Beta VTR and the Reference Input of your Kona 3, and that your Kona Control Panel is set to EXTERNAL REFERENCE, as is your Digi Beta VTR ? IS THIS CORRECT OR NOT CORRECT.

NO ONE SHOULD FURTHER ASSIST YOU until you confirm that you have a PAL Black signal going into your AJA Kona 3 and your Digi Beta VTR. Your Blackmagic HD Pro will also have a Reference input, which will be set in the same manner.

No matter how many post, no matter how many threats, no matter how many smart ass comments, no matter how many complaints that are received about my attitude, it seems that you STILL can't get people to lock their systems to black reference.

SO RORY, are you locked to PAL black, or not ?

I do have External REF in PAL using a Black and Burst and this has solved the problem in PAL.

I don't have a TriSync so the problem still there in HD.

Walter you would not have this problem as you using 60Hz and the Kona will using the incoming current to create its sync.

I'm on 50Hz and thus the problem.

Basically AJA need to sort there code out to fix this and its not my VTR, Mac Pro, HDLink or cables.. its down to AJA to fix this.

I now believe if I purchase a Trilevel sync for HD the problem will go away however this should not be necessary if AJA fixed their drives for the Kona3 in a 50Hz environment.

REPLY -
and now starts my usual rant. Most of you have heard it, over and over and over again. Rory, I DONT GIVE A CRAP IF YOU ARE WORKING IN PAL OR NTSC. EVERY DAMN SYSTEM IN THE ENTIRE WORLD NEEDS TO BE LOCKED TO HOUSE REFERENCE. I don't care what you have read, I don't care who you have spoken to. These people are ALL WRONG - even the ones that say "they have been doing it without sync for years". AJA needs to fix nothing. All hi end Blackmagic products (and everyone elses products) have EXTERNAL REFERENCE INPUTS. All Sony, JVC and Panasonic professional VTR's have REF Video inputs - NTSC or PAL. YOU MUST HAVE A BLACK GEN to operate - PERIOD. This is NOT A GAME or a challange. Whoever told you that "you dont' need sync" is a moron. AJA needs to fix nothing.

As for trilevel sync, and HD, you DO NOT NEED a tri level sync generator if you are operating at standard 25 frame rate. If you are running at 23.98, then you need tri level sync. In NTSC world, operating at a standard frame rate is called 59.94, and those that do not own a tri level sync generator that work in HD at standard frame rates (59.94) can keep using their good old NTSC black generators without issue, and without a tri level sync generator. If you are in PAL, and you own a standard 25 fps black gen from Horita, Sigma or so many other companies, and you are running at a normal HD frame rate (not 24p or 23.98) you DO NOT need a tri level sync generator.

As has been discussed many times, the new AJA GEN10 for $390 US will generate NTSC and PAL color black, as well as tri level sync at multiple frame rates.


AJA Kona products and Digi Beta VTR's in the US (NTSC) do not operate properly without External Reference. Let me make this a little more clear and specific. Forget the AJA Kona, forget the Blackmagic products, forget the AVID. Just think about the Sony Digi Beta VTR. The Sony Digi Beta VTR DOES NOT OPERATE PROPERLY BY ITSELF without being locked to a black external reference. This is why the little blue STOP light flashes on the front of the machine. When you go to a trade show, like IBC in Europe, or NAB in the US, you dont' see the blue STOP lights flashing away in the Sony booth and the Panasonic booth - even thought they are demonstrating their VTRs (and not editing systems) - do you know why ? BECAUSE THEY ARE LOCKED TO A BLACK GENERATOR - for BOTH NTSC and PAL applications. The Servo Motor needs to lock to something to run at the correct speed - it either locks to External Reference or the sync signal on incomming video. It DOES NOT MAGICALLY LOCK to itself.

Rory - this is what is going to happen now. You will use a PAL black generator (or if you feel like spending some money, a tri level sync gen like the GEN10) for THE REST OF YOUR LIFE, for as long as you are in this business. The next person that says "why are you using a black generator - you don't need to do that" - take a frying pan, and HIT THEM OVER THE HEAD WITH IT, and continue working. Your equipment will work, and I will feel better.

And remember, long after AJA and Blackmagic and AVID are all out of business, the NEXT GENERATION of PROFESIONAL video equipment will ALL use this black generator that you purchase. And when you die, your grandchildren will take your valuable PAL black generator, and continue on your legacy.

Hi...I'm in PAL land and we've set up Kona LHes and Kona 3s with the AJA HDP converter which goes to an Apple 23inch LCD monitor to work in both SD and HD 1080/50i PAL. The Kona 3 is fed with a standard PAL black burst reference as we're only working in 25fps.

No sparkles or any of the issues as Rory has reported.

so why when I feed my Kona3 a Pal Black & Burst I get issues in HD?

I've been working for years without using my Black & Burst as my old Decklnk HD card would use REF of Video IN a feature which doesn't work on Kona3.

Same with my Digibeta VTR which you can set to REF on VIdeo in.

How do you explain the problem I'm having that in PAL its fine now if I give Kona3 Ref in and in HD I get sparkles and issues?

I'm working in 25fps HD.

I've just picked up a Decklink HD Pro and will swop it out in my system asap and I'm pretty sure I will not have these issues - you can't tell me this is not a Kona3 issue

Rory,
We have a decklink hd extreme. We currently hire our digi decks in. (PAL)

I captured with TC without issues by just using a single sdi on in and one on out... thats it.. nothing else. No drops.. no sparkles. This is SD only. Not done HD capture yet apart from an xbox :-/

Bob, your posts are pure class dude.I totally see your point.And I respect your experience greatly. We are purchasing the AJA Gen10.

What I don't get is why it worked for us without sync. (we did hire BB just tried it without first and it was fine)

1) the GEN10 is a great product. It will not only provide PAL black and bars for you, it will provide tri level sync for the future (and NTSC black in case you get an out of country job

2) you need the DWP power supply from AJA with the GEN10. If you did not order this with the GEN10, it won't work

3) when you get your GEN10, make sure that your AJA Kona Control Panel in the control tab is switched to External Reference, and not internal, otherwise it will appear to do nothing.

This is driving me mad and having replaced all the components I'm not sure how to solve this.

Bob do you have any ideas?

Only other things I can think of is to replace the monitor and HDLink.
However a direct feed from the VRT works find so I would say the monitor and HDLink are fine.

Rory -
from all of these posts, I am confused about your HD VTR (if you even have an HD VTR). You have said (I think) that if you work in SD PAL, and lock your Digi Beta VTR and Kona 3 to PAL black, everything works fine, but if you work in HD, it does not.

OK - EXACTLY what is your HD setup - I know you have the Kona 3 and a standard PAL black gen, but what is your HD VTR, and do you have trouble when you digitize the footage into the FCP system, or do you have trouble when you output the footage from the FCP system back to the HD-VTR. And once again - EXACTLY WHAT MODEL # of HD VTR do you have ?

I ASSUME that even when you are working in HD, that you are working at a normal frame rate, and not working at 23.98 (your Kona Easy Setup is not 23.98) - because if you are, you will need the tri level sync gen. However, if you are working at a normal frame rate (even if you have 23.98 tapes), your Sony or Panasonic or JVC VTR should do the pulldown for you to a normal frame rate, so you can continue working with your normal PAL Black Generator.

ALSO - please tell me the exact model # of the PAL Black generator you are using.

I am SO HAPPY that you had the luxury of being able to afford to get the Blackmagic Decklink HD Pro, so we could eliminate this from the equation of trouble shooting. It's easy to say its the AJA or Blackmagic problem, but if you don't have the money, it's hard to make these determinations.

Please answer my questions about your HD VTR, your Black Generator, and the frame rate you are working at in HD, and I will resond.

Hi Bob

Thanks for helping me with this, I can't figure this out for the life of me.

1) HD VTR is the Sony HDW M2000. We hire this in on project thus I don't have access it it all the time. We have a Digibeta DVWA500P in house all the time, this is mine.

2) I work in normal frame rate of 25p or 50i. The AJA Kona Control is set to 1080i25.

3) My Black & Burst is a DVC BBG5
http://compositevideo.co.uk/product-detail.asp?id=1548&catid=76&manid=50&qu...

I have a AJA Gen10 on its way to me so thats another component to eliminate.

At the moment the HD deck is not with us although I do have one coming in on Friday.
So my setup now is

- REF in from the BB into the Kona3.
- Output from Kona3 into Digibeta DVWA500P and Output 2 to HDLink connected to LCD
- I open a PAL 25fps SD clip with AJA TV and view it on LCD via HDLink
- This looks fine without any Sparkles.
- Then I open a HD 1080 25fps clip captured in 10bit Uncompressed and play it in AJA TV viewing it on the LCD via HDLink.
- This appears with Sparkles and the image drops out sometimes but not always.

What do you think?

Rory -
Is the framerate of the tapes 25fps, or 23.98 fps. The HDW-M2000 Sony HD VTR has no ability to do a pulldown to a normal framerate. You must tell me, or you must find out, if your tapes where shot at 24p (it is typical for users of HDCam cameramen to shoot at 23.98 or 24p with the Sony CineAlta, and other Sony HD cameras). It is very important that you find out this information.

There are several "fixes" to this. If you have 23.98 fps tapes, you should lock your system to tri level sync (both VTR and AJA or Blackmagic), however a MUCH BETTER FIX is to rent the cheaper Sony J-H3 VTR (player only) to digitize with. This VTR has the 2:3 pulldown feature built in, so you can operate at normal frame rates - then you don't need to worry about tri level sync.

I can't answer anything else until you tell me how your tapes were shot (23.98 or 25).

Hi Bob

It was shot at 50i 25fps no 24 or 23.98.
This I know for sure as it was a major requirement on this show.

I did do a test where I have the HDLink in the same LCD as my Mac desktop and switch between the inputs to view the different feeds.

If I play the QT file in QT Player on the Mac and watch it fill screen all is good.
If I play the file via AJA TV or FCP via HDSDI into the HDLink and view that feed I get the sparkles.

Kind Regards

I'm working all the time with Aja Kona3 HD 1080 50i and there's not a single problem.
I'm 99% sure that's your problem is HDLink.
Try to rent some monitor with HDSDI input and you'll get the answer.

Rory -
you are going to do this test, or I will kill you.

Your Kona has analog Y Pb Pr outputs. Take the Y output of your Kona, and stick it into a TV monitor. It can be a consumer TV you have at home, it can be a security monitor you have for your office. Tell the AJA Kona Control Panel in the Control Tab to DOWNCONVERT to NTSC (composite or component - I don't care - if it's component, you will get a nice B+W signal, which is fine for this test.). Make sure that in the FORMAT tab, you have selected 625, and not 1080i.

OK, playback your video. We are now BYPASSING the Blackmagic HDLink. You are watching your video without the HD Link.
Do you see the "sparklies", or is it clean ?

(in all these tests, we never bypassed the HDLink).

My GEN10 arrived this morning and I've replaced my old Black&Burst.
I also ordered the K3 breakout box which should hopefully help matters.

Okay I've just connected the HD Analog from the Kona3 to my 34" LCD TV and it doesn't show any Sparkles.

I'm now watching the HDLink and the LCD TV and the HDLink is dropping and sparkling like mad while the Analog LCD TV is fine...

So this must mean I have a faulty HDLink... surely!!!

Well its the only thing I have not replaced... will sort this out now.

I was so convinced it was not the HDlink as when I feed it a signal from the VRT it was fine.
I'll be so happy to find out it is the HDLink and I can have my life back :-)

Rory - your problem is solved, and you have your life back right now. You have taken the AJA Kona analog HD output and put it into your 34" LCD TV, and there is no problem.

You have already purchased the Blackmagic HD Pro, which you can now return. You now have extra money. This is what I suggest now, now that everything is working -

1) do nothing, and keep using the 34" LCD TV via analog HD and the Kona analog HD output.
2) buy an AJA HDP, which is AJA's version of the Blackmagic HD-Link
3) buy a Dell 2407WFP for $600 US, that has analog HD inputs. This will make a fine cheap HD monitor with analog component HD inputs.

You have no more problems - problem solved.

Thanks Bob

I've returned the HDLink and will have a replacement on Monday/Tuesday.

Hopefully it will just work or I'll have to purchase a AJA version.

Will let you know once the new HDLink is back and the problem is gone.

Many thanks
Rory

Sparkles and drops in PAL
on Sep 29, 2007 at 4:42:33 am

I'm in PAL land too and I've seen sparkles and drops.

But I don't use a Kona3 not yet. I'm glad your problem is solved by by-passing the HD-link. But I don't think its your HD-link. Nor is it anything to do with ref. Though I'm glad all this made you get one, which is really what you should have always had.

Also, you should have tried all this with an NTSC project and an NTSC movie before surmising the 'only-PAL' thing.

Anyway, I've seen sparkles and drops in plenty of LCDs (never on CRTs) connected via DVI-D. Its a DVI-D thing. It happens with...

1. bad cables of short length.
2. average cables but of long length.
3. bad cables of long length.
4. bad connectors on LCDs.

And I've seen this problem on LCDs connected to...
FCP
Avid Media Composer
Discreet smoke/flame (linux and Irix)
Quantel eQ/iQ

I've even seen an issue where we saw sparkles only when working on a movie in Shake but that same movie lookes fine in QT player outside Shake.

It almost always goes away with either cable change, LCD change, length change, and in our case, extender change.

I saw this post only now else I'd have warned you to focus on the LCD and things near it first before changing your MacPro, Kona3, maybe even your house and car if Bob hadn't come along.

Incidentally I work in a facility with almost a hundred Macs - FCP, Avid, Shake, PixelFarm...like quantity of PCs - Avid, 3DsMax, smoke, flame, lustre, Quantel eQ, iQ. And I've seen a ton of sparkles. Happens all the time.
