    I have previously used an ADVC300 for all my VHS tape captures ... PAL S-VHS

    I carry out no processing just a straight capture using WINDV, why do the files show as being created using SONY DV codec ?
    Why would it use a SONY codec ?

    If I look at MediaInfo for the files they all show the following:

  2. MediaInfo always says "Sony" for the "dvsd" fourcc.

    OK .. in earlier post I was chastised for using the inferior SONY codec

    Found out that the ADVC300 appears to computer as if it is a Sony MiniDV camcorder's IEEE1394 interface. And its IEEE1394 output stream looks like a MiniDV camcorder output.

    My guess is you're using Windows' built in DV decoder to view the video.

    Yes, the ADVC300 has a DV encoder chip. It sends a DV A/V stream to the computer via firewire. WinDV just takes that stream and wraps in in a AVI container.

    For a giggle or two (not much else to laff about today) I did a few tests with my ADVC.

    First, I did two 'captures' with WinDV. The type-1 capture just shows 'DV' in mediainfo. Procoder identify this as 'LAV (dvcp)'
    The type-2 'capture' only shows the 'hint' and Procoder identify this as 'LAV (dvsd)'

    I then did two similar captures using Ulead DirectShow and these produced the same results as above.

    Strange then .... I am only doing a capture no processing, no conversion .... yet everyone of my files is tagged as SONY DV
    Are you using W7 ? ... could that be the difference

    You missed the critical difference. Only type-2 DV files have this. The type-1 file does not.

    And jagabo confirms my earlier suspicion(PM). Mediainfo does not always get it all right. I sense a little paranoia creeping in. I appreciate you want to get it right at the third time of asking.
