  • Convert all Audio in Timeline to same sample rate

    Posted by Matt Devino on April 29, 2010 at 9:48 pm

    I’m just finishing up editorial on a personal project and need some help getting my project ready for the Sound Mixer. I’m working in a ProRes 23.98 48k timeline in FCP 7. I have audio from a lot of different sources, everything from 44.1k AIFFs to 48k Camera Audio to 8k audio files I recorded over the phone using an iPhone app. Everything works fine in my timeline, but when I sent over my OMF to the audio mixer he couldn’t open it because of the different sample rates.

    So I need to get everything into the same sample rate for him.

    I tried doing a media manage of just the audio in my timeline using the “recompress media” option. This recompressed any video/audio files to 48k, but left all of the audio only files at their original sample rate.

    He is going to mix the project using soundtrack pro, so I tried sending the FCP timeline to soundtrack and that did work – everything came across correctly. The only problem is it’s just referencing the media on my drive, and I wanted to be able to just FTP an OMF or sound track project to the mixer (he’s on the East Coast, I’m in L.A.). Anyway to do this? Is there such a thing as a media manage in sound track?

    Any work around suggestions are much appreciated, whether FCP or soundtrack based, Thanks for your help in advance!

    Just use Compressor to batch convert them all. Keep the file names the same. Replace them in your media folder and reconnect if necessary.

    Next time don’t mix sample rates if you are going to do an OMF.

    The OMF export should have automatically converted the audio to 48Khz. the problem may be the 8khz material which I am very surprised to hear that it worked at all in FCP.

    It is always best practice to pre convert all material to 48khz before editing. It makes things go well in the timeline without beeps and renders.
