Audio Dropout upon capture FCP5
So, I just upgraded to Tiger as well as FCP5 and I have random, but consistent audio dropouts (1-2 frames at a time) when I am bringing in a voice track. I am on a G5 dual 1.8Ghz, 1.5g RAM and using a DSR-20 DVCAM deck. I have tried dumping prefs, changing decks (same model) and changing firewire cables and still the same. BTW I am not capturing to an external deck. This did not happen with Panther and FCP 4.5. I am up to date on the apps, and also have installed the “Pro Applications” update for Tiger. So I am now stumped. All comments appreciated. I am going to try a different model deck (DSR-25) to see if that makes a difference. Thought I would post here to get some feedback. Thanks all in advance.

Okay so the DSR25 wound up working. Anyone know why I had problems with 2 DSR-20’s since the upgrade? Huh? Compatibility issues?

Dsr-11 also dropped frames of audio, but much less frequent. Could this be an error correction thing that needs to be addressed. The newest of the decks (DSR-25) had no problems, then slightly older (our dsr-11) had some glitches, and finally our oldest deck (dsr-20’s) full of dropouts. This sucks!!

I’m lost.
You have the voice track on DV tape and it drops out playing in from the TAPE?
Or the audio drops out going TO the tape from FCP?
(Two very different things.)
If its FROM the deck, it sure sounds like a “glitchy” recorded tape (dub the master to another TAPE via FW and capture from the copy.)
If its dropping out in FCP, perform an audio Mixdown.

FROM the deck and NOT the tape. The tape plays glitch free on all four decks when you listen straight out of monitor, but as soon as it goes through firewire and into “log and Capture” the recorderd waveforms have visual dropouts. I didn’t have one dropout using the DSR-25 though – same tape.

This does not really change my answer.
The error-correction (sent to the analog outputs) in a playback deck or camcorder can compensate for many drop-outs and mistracking.
But the FW output could come more “directly” from the tape (no compensation).And any given deck’s heads might track a particular tape better than other players.
But problems like this can be symptomatic of many things (like a “cough and fever” in humans).
If you don’t like one answer, you can seek a second opinion.
