48khz > 32Khz

Hi,
I work with VV3.0c
I have captured some DV clips from a DVCAM tape with Végas Vidéo Capture.
Some of those clips seem to be in 32Khz/16bit (in the media pool).
Nevertheless, my DVCAM tape have been entirely recorded in 48Khz/16bit.

Any ideas ?
TIA
Gilles

Did you capture these clips with 3.0c? There was a pre-3.0c bug that caused some DV clips to be captured at 16/32, but that was fixed (we are pretty sure- can you repro on a new capture session?).

In any case, you can use those clips with very little if any audible difference. If you do indeed have 3.0c, and are still getting 16/32 captures, please let us know.

Thx for the reply.
Yes, i use Vidéo Captue 3.0c (build-138) and i still getting 16/32 captures.
My DVCAM tape was recorded with a Sony DSR40 recorder.
For the capture, i read this tape with a Sony TRV900 camcoder.

Thx

I just noticed, the média pool display : « Field order : None (progressive scan) » for some of those clips.
All those clips are in 48/16.

I am experiencing this bug right now using Vegas Video 3.0c

Here are my questions:
- has anyone noticed any problems using the mis-interpreted 32K audio track?
- is there a way to fix the file so it is interpreted as 48K?
- has anyone figured out why this bug seems to go hand in hand with the associated video track being slightly shorter or longer than the audio? (when you drag the end of video, the audio doesn't trim in sync with the video because the lengths are slightly off)
- why do I get a 'Progressive' flag on a captured video clip every once in a while when all my content is interlaced? seems to be a related problem.

I have already been editing this video for several hours and the idea of re-capturing it isn't appealing, but if that's what I have to do to make sure my audio isn't going to be corrupt, then I have no option.

using:
Sony DSR-11 DVCAM Deck
various tape formats from various cameras. the clip that came across as 32K this time was from a miniDV tape... camera unknown, but I don't think it was a cannon because there are no black bars on the edges. does anyone know of a DV file reader that can read the metadata stored by the camera?

thanks all!
