Tom,
Ping me outside of the DUC with what the menu settings are on the DVW-A500 you are using. We have
never had a problem with checking audio sync using the jog wheel on a DVW-A500.

I've really begun to mistrust scrubbing tape to confirm audio sync after a couple of recent experiences;
|
I don't trust it on the AJ-HD3700B or the SRW-5500 at the moment.

In one case, a Digibeta tape was kicked back for a dropped in section at the end being one to two frames late. Later, the same tape was checked again, this time the same section was supposedly 10 frames late. The tape had not been modified!
|
Are you only inserting audio? I suspect the answer is yes, but I have to ask.

The only difference was the QC tech and that the first test was done on an SRW-5000 and the second on a DVW-A500.

Well, I think that difference (read - failure) falls on the QC department. They should be performing QC on whatever deck will ultimately be used for playback. I understand that the SRW-5500 will playback a Digital Betacam tape if you have an option card in it, but playback and operation may not be the same, as we're discussing now. We use a SRW-5500 to playback Digital Betacam, but we're not performing QC on our laybacks or clones with that deck. We do that work on a DVW-A500.

The other case was after I'd layed back a fix for one of these tapes, I was using the remote serial controller that the QC techs use to scrub the tape and check sync. I found that I could fairly easily get the sound to play up to a frame and a half early or late when jogging back and forth and then down to a still frame (with stuttering audio) as the QC techs do.
|
I don't recall getting the stuttering audio, but on the AJ-HD3700B I can absolutely get the sync error to be 2-3 frames by jogging slowly.

On top of everything else, the QC techs are using a flat panel (supposedly delay compensated) while I'm using a CRT...

You may want to find out if those QC techs are going to AES, and if so, tell them to
attend this session.
