Exporting audio with SMPTE
on Feb 18, 2010 at 2:39:16 am

Simple question: (Maybe not-so simple answer)

I am using FCP and need to export audio tracks w/SMPTE code.

How do you do?

If you export an OMF it has the info on where the files sit in a sequence timeline so an OMF will import into an audio system with the file correctly synced to the sequence timecode on the correct track.

Or do you mean a file like broadcast wav with embedded timecode metadata? More info on what you are trying to do will help.

Yes it's an audio file to be sent for transcription. So yes, a wav file with embeded metadata. It will be read only by the transcribers.

Thanks!

Can the transcribers play quicktime files? You can export the audio in a quicktime wrapper as later versions of quicktime player can read the embedded timecode. You could also provide a burn in on the video track or do they need to extract the timecode info automatically from the file? Most transcription services that I use take quicktime files.

Otherwise can they read broadcast wav and its embedded timecode?

It's in fact easy:

Import a QT, and you get a SMPTE LTC audio track.
Paste that in your timeline or in your QT and you're done.

If you have a batch of clips to do, contact me and i'll write something that will do the pasting for you.

@ Vahl

This program works great but I'm looking for a program that also carries over the audio (converts multi-channel audio quicktime with source timecode to BWAV file with same source timecode). Any thoughts?

wave to BWF is simple, get qtchange from my site.

However, it only does stereo or mono.
If could make it to work on any amount of channels, but that would require a day or so of coding.
How important is it to have poly files instead of multiple Mono?

@ Bouke,

I saw this tool but yes we would need all channels to transfer straight across. Here's an example quicktime movie we'd need converted:

The goal would be to produce a broadcast wave file with the same timecode stamp, same frame rate, same clip name, etc and all mono channels transferred across (up to 8).

Adam,
Downloading now.
I'm pretty sure i can make something, but it depends if you want P or M files.
Since this thread is very old, contact me direct at bouke at videotoolshed dot com
