AJA Audio Bad, Line out Good
short version: I captured material via HDV, which played back fine. I then added a new Convergent Design HD-Connect MI, captured material via SDI (ProRes422). The capture quickly aborted due to “VTR Problem.” I then disconnected the HD-Connect’s Firewire-to-RS422, and captured the tape as an uncontrollable device (w/o timecode of course).
Result: audio clicks, sync problems, dropped frames.
Added Result: HDV files have same problems, despite playing properly before.I have done everything I can think of: trash prefs, uninstall Kona software, restart, use Kona VTR Xchange, isolate computer from all firewire inputs (which fixed a similar problem once).
Oddly, I can play the HDV captures with no issue, as long as I use FCP/Audio-VideoSettings/Audio Line Out. But when I switch that setting back to AJA Kona audio, I get the audio clicks and dropped frames.
Eventually I’d like to make the HD-Connect work, but for now I’d be happy to be back in business, and fix the problem which using the HD-Connect apparently triggered.
Long version:I’ve been having problems for a long time when trying to use my Kona LHe for high definition captures. Here’s an earlier thread: https://forums.creativecow.net/readpost/98/865467
Is this a hardware issue? Since I keep having similar problems, any basic suggestions? Including hiring a local FCP guru to come in and fix everything?

What is your reference set to in the Kona CP?

Does the HD Connect accept reference? Have you tried referencing the HD Connect and Kona?
It sounds like a ref issue to me.

No reference into the HD Connect (the picture on the HD Connect capture looked fine.)
I still have the problem after taking the HD-Connect out of the loop entirely (disconnected every wire to it). I’ve done all the normal things: deleted prefs, reloaded Kona software (three times so far), restarted MacPro…
Just captured a short HDV clip. It plays back fine until I try Audio-Video Settings: AJA Kona audio.
I took your earlier advice and made Kona CP visible to see whether the ref in setting changes — it’s still Free Run.
It’s really odd that when I play back a previously successful clip, I get the same lost frames/audio clicks. This is very bad for me, because I have a deadline of tomorrow on an edit that I apparently can’t use the Kona card to export now.
I wonder whether it’s hardware. But it’s so strange that this problem came back just when I tried SDI input.
I am in rather desperate straits at this point, and would appreciate any advice! It must be something so simple I can’t think of it.
Thanks for your help.

Have you used an AJA Kona HDV easy setup?

What version of FCP, QT, and Kona drivers is everything?
Did you uninstall the Kona drivers before reinstalling?

Thanks Jeremy. This seems to be a very weird hardware problem.
(to answer your good questions, FCP, QT, Kona all up-to-date. I uninstalled Kona before reinstallation.)
Under guidance of AJA tech support I swapped out the break-out box, found the problem disappeared. Then I reinstalled the break-out box and selectively plugged in various inputs/outputs. When I unplugged the Analog Video In, the playback problem disappeared. Go figure. The Analog Video In actually works for input — but aborted the playback.
Further muddle: when I replugged the Analog Video In cables, everything now works. So AJA is now replacing the break-out box and the umbilical.
Does this make any sense at all?

Not really. Glad AJA was able to track it down.
Thanks for posting the results.

Thanks for helping out. When your deadline is looming and you have one machine, and it ain’t workin’… it’s mighty nice to get a helping hand.
