    I need forty-five minutes of non-drop-frame smpte linear time code (starting at
    0:57:00) to use to synchonize some files I created in ProToolsFree, but have
    not been able to find such a sample on the web. Anybody know where I could
    download such a file? (and given the file, how would I see by looking at the
    wave form where each frame was, or at least where each minute was?)

    (I'm often at rec.arts.movies.production, but figured this would be the better
    place to ask)

    you can rent a time code generator from your local video rental house
    for $10 or so per day. Does the free version of protools even accept
    time code or are you putting it on a audio channel? That's nice if it
    does. The real version syncs to sources via SMPTE spiggot on the inout card.

    I'm putting it on a channel, and then (maybe) on CD so that a digibeta MOS tape
    can be married to the sound it belongs with prior to making DVDs with it. I
    don't have any cards, just the program (and it's a great program!)

    Watch out. DBeta needs timecode and digital audio words to be synchronized
    to the vsync rate.

    Also, without that lock, there's a good chance your track will drift a
    frame or two by the end of 45 minutes.

    Also, check with the post or mastering house (or whoever's doing the
    resyncing). They might charge very stiffly for non-standard timecode
    tracks, which is what you're suggesting. It might be cheaper for you to go
    in with your audio on CD, and roll it in yourself.

    FWIW, one of the studio suppliers used to sell a CD with timecode on one
    channel, and an announcer calling out the numbers on the other. It won't
    address these other issues, but will do what you want.

    I started with 18fps film, and transferred to video at 17.982 with a 3:3:4
    pulldown. So every film frame can be identified with a specific set of video
    fields. The sound track is in ProTools, and referenced to "beats" that give me
    18 references per second, and that sound is in sync with the film. (It's a
    transfer from fullcoat with a second channel of pulses that match the beats).
    So it's in sync in ProTools. If I can put a time code track in ProTools that
    matches the film frame rate (that is, matched with the ratio 18:30) then that
    track should be in sync with the video.

    No?

    I imagine that when the house marries the two, the machines will keep the time
    code in sync and therefore the sound will be in sync.

    No?

    What would be non-standard about this timecode track (starting at a bit before
    1:00:00 so that first picture falls properly)?

    Alternatively, I could just supply the CD audio (with a 2-beep) and let it play
    wild. How much drift would there be in 45 minutes between CD and DBeta?

    Do you remember which one or who made it?
