Edit to Tape – disappearing audio
Mastering to DigiBeta through Kona2 with Kona VTR control in FCP5.03 in ASSEMBLE mode.
Have problems with audio not always being recorded – though the audio clearly passes out to the VTR and is audible. The audio seems to be on tape when scrolling, but does not playback. Tried with embedded, AES-EBU, and even analog audio – but still the same problem.The facility House from where I rented the VTR have no problemswith it on their AVID suites.
My guess is that it is an issue with the VTR control (Kona RS422 connection) – maybe an FCP issue – that causes the VTR to be confused and not insert the audio properly?
Tried to download latest Kona2 driver but the problem remains!

Check to see that the Channel condition lights are not red. It sounds to me like this is a channel condition error. That could mean one of two things. Make sure you are locked to external sync.

Try this.
When you are attempting to play back the tape be sure that you only have the OUTPUT of the K2 going to the INPUT of the D-beta deck. You will notice problems if you ahve the decks input and output hooked up at the same time.
WHen I output without a BB gen I only send the OUTPUT of the K-Box to the D-Beta. To watch it back I unhook the OUTPUT and watch.
Try that too, but look at those channel condition lights. This is probably because you are trying to OP without the DECK and the KONA locked to the same black (sync) source.

Be sure that the deck’s reference is set to VIDEO INPUT, not REF.
I have also had this problem with QT exports with missing segments of audio. I found that trimming certain media and/or moving the offending media to another audio track will fix the problem. But it may take a bit of effort.

I think I know what went wrong. I usually set the deck’s TC to PRESET in order to stribe the tape with black from timecode zero. (Can’t get stribing in FCP to work properly – the TC has it’s own life).
And I think I forgot to set the TC back to REGEN for Mastering…!– No Parking Production –
