Mixing audio of different sample rates....
by Matthew Abourezk (Mabou2) on Jun 23, 2008 at 2:12:09 pm

Hi all,

I don't have time to experiment, so I am hoping you can help me.

I am a bit confused about the "Big Picture" of how FCP wants me to handle sampling rates for different video formats.

I am shooting an exercise video in HD (with an HVX 200) that I will edit and eventually output as a SD 16:9 DVD.

When we shoot, the audio will from the camera will be @ 48Khz. The client has provided CD music that is 44.1Khz. Play that CD live during the shoot so the girls have something to workout to. Then I need to use the music in the FCP timeline for editing.

Is there ANY reason why I should change the sampling rate of the CD audio to 48K before I drop it into the FCP Timeline? We will most likely do all of the editing in HD, then output the finished piece as a SD 16:9 movie for use in DVDSP.

Any input is appreciated.... including warnings of potential issues.

Thanks a bunch,
Matt

To keep it simple, convert your audio file on the CD to 48Khz. FCP was designed to work with 48Khz.

insert your CD into your Mac. Open audio file with QuickTime and export using 16bit 48khz.

Alternative is convert file via iTunes. If you have many audio tracks, you can bring the files into FCP and do a batch export.
