1. Re: DV sequence - 32khz or 48khz?
Bill Hunt Feb 10, 2011 5:31 PM (in response to BJBBJB1)I believe most of them are 12 bit audio so that translates into 48khz
Here, you are confusing the Bit-Depth, and the Sample-Rate Usually, 12-bit is used by cameras that allow one to ADD narration to the tape. A choice of 16-bit Audio is the best choice for editing, as one can easily add that narration in the NLE program.
Now, PrPro can handle quite a few Sample-Rates, but given the choice of 48KHz (the Sample-Rate of DVD), it will never get better than that.
Regardless of what has been shot, PrPro will need to Conform the Auido stream(s) to 32-bit, floating point, for internal editing. This will be regardless of what the settings are. It will take a bit less time to work with 48KHz, but 44.1 (the Sample-Rate of CD), or 32KHz should work fine, and only take few moments longer.
If you are going to DVD-Video, and the footage has not been shot yet, choose 48KHz 16-bit Audio, and you will not get better than that.
Hope that this helps, and good luck,
Hunt

3. Re: DV sequence - 32khz or 48khz?
BJBBJB1 Feb 10, 2011 6:48 PM (in response to Bill Hunt)Bill,
Thanks. I understand that for new footage I would choose 16 bit for my source and I do. I also now understand that regardless of what I do, P Pro will confrom it to 32 bit floating point for editing.
But for the recordings I already have, that might be a mix, and after reading your post and the linked post, am I correct in that since my final product is an SD-DVD, I should just choose 48Khz for my project/sequence and I would be okay regardless of whether my source audio is 12 or 16 bit? And that way I would not be losing any quality during the editing process?

Bill Hunt Feb 11, 2011 8:16 AM (in response to BJBBJB1)Yes. In this case I would choose a 48KHz 16-bit Project, and let PrPro handle things from there. In most cases, it can ingest quite a few different standard aspect Audio files, and Conform them. If you run into any problems, just rip the Audio and in SoundBooth, Audition, or the free Audacity, do a Save_As PCM/WAV 48KHz 16-bit and Import that.
Good luck,
Hunt
