Massive Audio Sync Issues with Kona 2 and Dual 2.7 on Batch Capture
Read the audio sync posts below and I HAVE to batch for on-line. Batching produces loss of sync from 2-5 frames (seems to be consistent on each clip). HD-SDI from 1200A using RS-422. On-lining three TV shows on a deadline and they are all a complete mess. We bought this system three weeks ago with the understanding that Kona works closer with Apple than any other vendor. Hard to believe at this point. This is absolutely unacceptable. I really need to pick up the phone and scream at someone. Have I done something or installed something I shouldn’t have? I will gladly eat crow if this is my fault and someone has a solution.

From AJA:
Hello,
We are looking to have a beta driver Tuesday or Wednesday of next week.
For now individual clip capture will assure AV Sync.Will Simpson

Sorry PC , but this is very much a Qt 7 / FCP5 issue I would have never installed a brand new version of any app to do production on within 90 days of its release.

We have the exact same configuration, except we installed OS 10.3.9 not the dual 2.7, and we have a different Raid.
We have no sync issues if we set the KONA Control Panel to sync on Video In before we begin the batch capture.
If the KONA Control Panel is set to sync on Ref In or FreeRun then you will get a 2 -4 frame audio sync offset as well as an audio pop at the head of each clip of the Batch Capture.

Aja says they are working on a new driver to fix the problem. Not Apple. I can’t find anyone complaining about the same problem when digitizing through firewire. I’m not sure if Blackmagic claims to be working with Tiger/FCP5/QT7.
Aja put out this press release April 19:
>AJA Video today announced that all KONA and Io products will
>support Apple -
Thank you very much for the info. We’re going to try ASAP.

Alright, didn’t mean to sound contentious, I’m not so naive to think that just becausse someone announces a product that it will work. Years of experience with Avid, Discreet, Apple, and Pinnacle certainly makes this whole issue a raw nerve that just gets hit again and again and again. It’s explaining things to my clients that rubs salt in the wound.

PC,
Read this thread below,Steve Swersky found this out and reported it to AJA a few weeks ago.
This is the thread

you will have good sync if you load one clip at a time as AJA suggests.

You can capture on a clip by clip basis using a -3 frame offset. it’s not exact but it’s close enough, audio maybe a half a frame ahead of picture. I’m in my third week of a feature and have had to add extra personel to work the graveyard shift to keep up with dailies, I’ve found it faster to bite the bullet and batch without sound and use the backup audio from the mixer. I’ve had to spend extra on a DEVA 5 hard disk sound recorder because it writes to DVD at the end of the day and it’s easier to bring in the sound and sync up that way. Dat tapes would be impossible to get through in a night. I tried to capture clip by clip but with two units amd many cameras it’s impossible to keep up.
It’s commom for equipment companys to lie to their customers, they all do it, it wouldn’t hold in court. It’s like actors lying on their resumes, they all do it.
Wait till you try to make DVD dailies, or play back footage on a laptop, you’re in for more surprises.
