  • Exporting a quicktime w SMPTE timecode on a separate audio channel

    Posted by John Squire on November 12, 2012 at 7:36 pm

    I’ve got a client requesting a ProRes QT with SMPTE timecode on a third audio channel. Am I crazy or is this just for tapes. How would I do this.

    Thanks.

    FCP doesn’t generate LTC which is time code data in an audio stream. Tape machines do.

    What you need is a wav or AIF of LTC with the same timecode as your sequence and put it on a third audio track. Make sure your sequence is setup to output more than a stereo mix and patch the timecode track to output as channel 3. It would be fair to ask why of your client as they may not know how timecode works with QuickTime files.

    I would search the web to see if audio files of various time codes are available to download somewhere.

    Yeap.
    As Michael say, TC can be recorded on audio tracks on tape, but no idea on how to get that done in FC, neither I understand what’s the posterior utility of that TC.
    The only application I know able to read that AUX TC recorded in a QT audio track is “Videotoolshed”.

    250 bucks.
    As Michael suggest, ask your client what a heck hi is trying to do with that.

    Any time I’ve been asked to do this, it’s for a good reason. Many projection systems that intend to run synchronized lighting displays use the LTC output from the player to sync the lighting rig. Here’s how I usually do it – output my file to a tape deck with TC, then recapture from tape, grabbing the audio LTC as it plays from the deck.

    This seems to be what I want, seeing how I don’t have access to a deck where I’m at right now. There’s even a LTC generator for 150.

    I can add the track to the quicktime now, but is there a way to not have it audible when I playback on a computer? Have it be a third audio track that’s not stereo?

    Thanks for the link.

    John,
    If you have added a TC track (note, it’s a QT track, not channel)
    you can mute it.
    Just open it in QT pro and go to properties.
    Select the track (probably the lowes one), and select the ‘audio settings’ tab. Then mute it.

    hth,

    Bouke
