PRINT TO TAPE SONY DSR-30

While capturing from SONY DSR-DSR30 works fine, print to tape or print from timeline does not work unless you do the trick to put the machine in unlock audio. The same machine from where the clips are captured simply does not record and automatically enter in stop. The product I obtain here is unacceptable, a DVCAM with unlocked audio as in DV. Any suggestion?

What is it about the unlocked audio that is presenting a problem for you?

Carlo,
this isn't a real issue. The (un)locked audio really only has relevance to cameras, well at least as I understand it. The DV spec permits the audio be out of sync by upto 2 frames if the codec needs more time to encode the video, idea is no one can pick a momentary two frame shift in the audio sync, also its most likely to happen during very fast motion and that usually doesn't happen when lip sync is noticable. What woud be noticable is if the camera rendered pixelated video.

Some of the latest DV cameras will generate DV with locked audio, and I'm pretty certain that decks such as the DSR 11 and 45 will record in DVCAM with unlocked audio without any tricks.

The real issue if you're really worried about this is does VV loose audio sync to the extent the DV spec permits during render. Once the video is rendered its just one and noughts, all the VCR can do is record what its given when its going in digitally. As VV isn't rendering in real time (unlike a camera) I can see no reason why it wouldn't keep perfect sync.

If anyone else knows anything to the contrary I'd like to know also.

Thanks for your explanation. This is undoubtely due to the fact that the DSR-30 is and old machine (but reliable as anyone else, got it 6 years ago and still working fine with no maintainance, my older Betacam would have needed at least 3 o 4 replacement of heads). Probably the DSR-V10 is doing the same (recording in unlocked audio) but does not give any warning.
If the machine works properly in terms of that it gets exactly what comes out of Vegas I am fine. I was worried because after several editing platforms and cards this was the first time I got this warning
Thanks a lot
