<p>Hi, Jim,</p>
<p>I checked Tim Stoffel's magnum opus on VTR formats
(<a class="moz-txt-link-abbreviated" href="http://www.lionlamb.us/quad/format.html">www.lionlamb.us/quad/format.html</a>) and he says DVCAM (which has 40
and 184 minute cassettes on 1/4 inch tape) has:<br>
</p>
<pre> No. of digital channels: 2 Sampling rate: 48 kHz No. of bits: 16
(Or, 4 32 kHz, 12 bit channels)
</pre>
<div class="moz-cite-prefix">According to the same resource DVCPro
and DVCPro 50 are both 48/16 with 2 and 4 channels, respectively.</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">There seems to be some confusion online
in the forums, but many posts seem to agree with Tim's posting. I
don't know personally.</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">So, since you are transferring from the
DVDs you made, that would most likely be 48/16 PCM on the DVD as
well since it came across digitally from the MiniDV player. It
should be an exact clone. Although there are options for other
audio formats in DVD (including AC-3 and DTS), I'm thinking if it
took in PCM it wouldn't convert it to a lossy format.</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">I have not thought about this for
years, but what I found sounds like what I thought it was from
back in the day.</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">Cheers,</div>

<blockquote type="cite">f I recall, mini-dv was a medium dedicated
to Sony's lossy coded format. If I'm right then the so-called
"16 bit 48 kHz" files are lossy encoded. The lossy encoded
wordlength in the file is apparently 16 bit but when decoded it
will expand to 18 bits in linear pcm format (formerly lossy
coded) or more.

And if I'm right then David Josephson's point about finding the
original player makes sense and you have to play it from the
original software. I suggest having a bit-scope on the digital
output to sense the output wordlength coming from the decoder.
You could do that by playing the dig out (SPDIF) into a good DAW
and run a plugin called "bitter" on the bitstream.

Thanks Bob. The dubs I've made to DVD were Firewire from a
semi-pro player (not Sony) to a standalone DVD recorder that
claims to enhance toe video. For all of that material I
simultaneously recorded the same mix to 2-track DAT.
