FCP firewire dubbing to Panasonic AJHD1400 deck.
I’m trying to output a 1080i sequence (:30) to my AJHD1400 deck. Picture is getting there fine, but I have dropped frames when setting the audio playback to DVCPRO HD out.
When I select internal audio, it plays back with no problem. But, I have to send it to the deck, so that isn’t a solution.
Anyone have any thoughts who has the 1400 deck and outputs via firewire? Is there a menu setting that needs attention on the 1400?

Have you mixed down your audio? How fast are your drives? Is the deck set for 1394 in?

Oh…meant to say…when audio playback is set to DVCPRO, it the audio actually goes out to the deck for about 3 seconds…then there is the “dropped frames” issue. But i can start the sequence from that point…and play out again for about 3 seconds then freezes up again. The audio file is fine. Everything is rendered.

It’s one single wave file. And yes, deck is set to 1394. Is there a menu item?

Select all in your timeline > hit apple-option-r and try again.
Also, how fast are your drives and what kind are they? Do you have the deck and your firewire drives hooked up together? I need to know these things to help you.

Try to rewire how the firewire signal is being routed. Take everything else off the firewire bus.
How full is the SATA drive?
Is it an edited timeline you are outputting?

There is no other firewire device hooked up. The SATA drive is only 30% full. It is an edited timeline I’m outputting.
And by the way, The exact same problem occurs whether it’s this 1080i sequence, or a different 720p sequence. Audio plays back fine for only 6 seconds…then “dropped frames” and freeze. Video plays perfectly.
I’ve tried different sound files to see if it could have a corrupted track…but the exact same thing happens.
Picture and sound digitized into FCP through the same deck and same firewire cables/ports…just as clean as a whistle.

Maybe FCP is reporting eroneuos dropped frames. This has been know to happen if not everything as speaking correctly between QT and FCP. Why not try the output without the drop frames warning, monitor the deck and actually see if the audio is dropping.
It wouldn’t be the first time FCO reported dropped frames incorrectly.

I had already turned off the “dropped frame” warnings…but the audio dropped out at the same point (goes for 6 seconds…then out). I can cue up anywhere on the timeline…and it will the audio stops 6 seconds later. It’s as if the buffer fills up.
It’s quite a puzzle to me. Thanks for trying to help, David.

Does it do this if you use Print to video?
Have you tried it to another deck.
I am going to give you one tiny tip.
Move one of those early audio edits by one or two frames and see if the problem persists.

Please mix down your audio, if that long wav file is not on you rmedia disk, it will drop frames. Mixing down the audio writes a temp render file to your media disk and will be faster than wherever you have it stored now.
