FCP audio VX1000
background) I have fcp 4.5 set up for use with my vx1000. I have athe capture and preset settings to 32 khz for the audio.
1)my question is basic I am assuming that fcp is handeling everything at 32khz, a departure from the normal 48khz. If I want to bring in cd quality audio do i bring it in as 32khz (aiff) or does fcp still want it at 48khz. i want to limit the demand on my cpu so i do not want FCP to have to convert on playback.
2) Also on output does fcp convert back to 48 or does it remain at 32khz. how does this all impact apack?

Last question first – the sampling rate of playback is determined by the output settings under audio/video preferences. It can be 32k, 44,1k, or 48k. It should match your workflow, in your case 32k.
First question next – simply import the CD track at 32k – in Quicktime Pro, Sound Converter, or other audio utility.
My question – Why are you acquiring at 32k anyway? “CD quality” is 44.1/16bit, so you are losing resolution (audio) when you import to 32k. I’m not very familiar with that camera but it should do 48k. It may make more sense to convert the camera audio to 48k – The difference in the load on your processor is next to nothing and your audio will sound better. Also, if I’m not mistaken, audio captured at 32k is not locked to video and will shift sync over time, whereas audio at 48k has the ability to be locked and will not drift.
