DV-AVI type 2 - 0.46sec of audio captured

[fberreth]

Hello folks,

I need your help. I have the same problem that kakomu (hope I spelled that right) had in July 2006. I captured a tape as DV-AVI type 2 and the audio is 0.46sec long only. Video is fine.
However, I cannot recapture the tape since I don't have it anymore :( Looking at the file size though I noticed that the file is large enough to contain audio (comparing with other tapes I have that have audio), so my hope is that DVIO which I used for capturing the tape simply "forgot" to update the header after all was captured. Is that possible? Is there a tool that can scan the AVI file and tell me what streams are in it w/o looking at the root header (or whatever this is called)?
Basically, I am trying to get this tape to work and holding on to a straw ... please help if there is any help ...
The audio is shown as 32khz, 12bit (may or may not be right).

Thanks,
Frank.

try open in virtualdub and listen... ?

also, several multi track nle are capable of showing audio and video tracks separately

Sure, I tried open this with vdub and vdubmod and both say audio is 0.46sec long. The audio stream should be 48khz, 16bit and about 55min. Since DV-AVI type-2 stores audio twice, once interleaved and once in a seperate stream I am thinking that it may have one of them messed up (probably the seperate stream).
I am wondering if I can get the audio from the interleaved stream that vdub is not looking at at all (that is why you can't open DV-AVI type-1 streams). Or maybe it's just the header screwed up?!?
What tool did you refer to that can "look" at the individual streams?

Forgot to say: VDub thinks audio is 32khz, 12bit. I know this to be wrong that's why I thought maybe it's just a header screw-up because the file size would have enough space for audio in it ...

VDub thinks audio is 32khz, 12bit

this should be ok, on may videocamera (Sony ) audio can be recorded on 16bit or 12 bits but always at 32khz.

just open in premiere or pinnacle or womble video wizard ... and look it

you can try even with avi2wav (google it)

good luck

Hi!I captured a tape as DV-AVI type 2 and the audio is 0.46sec long only.Your statement isn't totally clear.

Have you tried to PLAY the file on your PC, to see if it plays with audio?

[fberreth]

Yes, I tried playing it back with no success. As I stated, VDub thinks audio is only there for 1/2 a sec. even though the file size and length indicates it should be there for much longer.

I have tried Avi2Wav and it gives me the error message "XX" is not a valid integer value where XX are some weird characters.
Womble MPEG Video Wizard can't make anything useful out of it either.
