what is the sample rate / width of your incoming audio and what is the
project settings.

That's normal. Audio needs to be conformed for every project.,
although it shouldn't take that long to conform.

Not normal in my experience. 99% of the time Premiere does
NO "conformation" or "rendering" of audio at all, and 1% of
the time it takes a few milliseconds, just long enough for an
old human like me to percieve.

I agree with the other response that Mr. Starsick seems to
has a significant mismatch between the clips he is importing
and the settings of the project. Likely a difference in sample
rates (32K or 44.1K vs 48K) or maybe even word-width
(12bit vs. 16-bit).

Since I primarily use DV for video, I make it a point that
everything I do (for video) is 16-bit @ 48K, sometimes mono,
sometimes stereo, depending on what it is. I frequently
videotape live music performances and then strip the audio
track out of Premiere and use CoolEdit/Audition to down-
convert to 44.1K to make audio CDs from.

We are assuming that Mr. Starsick is *really* seeing AUDIO
"conforming" and not VIDEO. One way to test this hypothesis
is to actually render the audio separately with the menu option.

The clips I am capturing have an audio sample rate of 32k my premiere
project is set to 32k clips are about an hour in length and take about
1/2 hour to conform. I am unable to do anything elese while they
conform. My workflow starts at with a live signal being sent through
panasonic AG-DV2000 (basically a $2000.00 transcoder at this poiunt)
and is captured directly to hard disk with Win DV these files are
transfered acroos the network to my PPRO station then imported into
PPRO at this point the conforming starts and really slows down my work
flow. I have also captured DV within premiere and when the capture
is done it still conforms the audio.

besides that everything else works great.

That's odd Josh. Premiere shoudl only have to conform or render when the
audio is different from the project. When you look at the properties of the
clips are they 12 bit/32Khz? Because Premiere will probably only do 16 bit
32Khz. Could it be that is the difference?

Also, what happens if you set Premiere to 48Khz or 44.1?

How can you say this? The help file in Premiere Pro plus everything I
have been reading on this forum and the Premiere Pro forums seems to
indicate my experience is normal- that audio is conformed each and
every time by necessity for each and every file that contains audio in
each and every project in Pro 1.0 and 1.5.

From the Premere 1.5 help file:
--------------------------------------------
When you import audio into a project, Adobe Premiere Pro conforms the
audio, converting it to the current audio sample rate for the project
at 32-bit quality. Once audio is conformed, no further conversion is
necessary except when you export to a format that uses audio settings
that do not match the project settings. Conforming audio affects
editing performance and project file management in the following
ways...

ahhh.. but some mixing/sample rate conversion takes less time than it takes
to put up the progress bar. Especially for like sample rates and widths.
Normally I never see any indication of Premiere rendering audio.

Maybe annother good reason to avoid "Pro"? I have been using
Premiere since 5.0 and currently using 6.5. I have edited >100
hours of video on several different computer systems with Premiere.

I repeat that it is so rare that I have ever seen audio rendering that
I truly can't remember when the last time was.

Pro rocks. Faster than any version so far
