    Are clapperboards useful, or is it all just silly posing about?

    I can feel the ascending collective incredulity of clapperboard loaders
    across the land!
    Where sound and vision are recorded separately - e.g. film camera + DAT
    recorder - the clapperboard provides both a visual and audible cue to enable
    the editor to sync up the two tracks when it comes to the final edit.
    But surely that much ought to be obvious! :)

    Yes, that bit was indeed obvious. :)

    I was wondering more about the info boxes they have - I was looking at some
    for sale online, and some of the boxes didn't seem much use for someone
    making a short film using one video camera ('director' and 'cameraman' seem
    completely superfluous, and I'm not sure about 'reel').

    Not just that. I'd use a clapperboard to synch the editing of two cameras
    that were shooting a wedding at the same time, if doing so didn't make me
    feel such a tit.

    As it is, I use camera flashes on the video, and (if I have separate audio)
    manually line up the waveforms.

    No - the boxes aren't necessary for that sort of production. As you can put
    a sticky label on a tape, even the "reel" is a bit superfluous.

    It is very handy for celluloid film, as it puts an ID (of sorts) on the film
    itself. A label on the can is no good, because the reel might be put back in
    the wrong can. I was under the impression that celluloid film is transferred
    from reel to reel by each playback, so labelling the reel itself is not an
    option (though I could be wrong about it changing reels), and labelling the
    reel might also throw it out of balance (could be wrong about that, too).

    Weren't the clapper boards used to label and identify the many takes of
    each scene, and the particular scene itself, on a film reel, as well as
    to allow synching of the sound (which was usually recorded separately
    and striped onto the film at the editing stage) ?

    Considering the cost of film, that sounds more plausible than my "lost can"
    theory. An old fashioned split-by-scene: Can't do it on computer by content
    change or timecode, so eyeball for the clapper and use that to make the base
    cuts.

    :eek:)

    Are you still on mug-sw?

    Just asking because the SiT2005 DVD is now available.

    Very useful to serious film makers, very silly to those who are just
    filming the kids playing in the garden - IOW, if you don't know what
    Scene or Take numbers etc. are then you probably don't need a
    clapperboard (or the modern equivalent).

    As others have said, a clapperboard is more than just a means of
    syncing the picture to the sound, much useful information can be
    recorded to tape for later use in the edit without the risk of
    loosing paper notes.

    Given that I probably won't even fill one tape for the project I'm planning,
    I tend to agree. And, once it's transferred to the computer, the tape is
    there to be reused.

    Well, the record on the film would only identify the reel that it started
    on. Assuming the various takes are then cut into individual strips of film,
    then the clapperboard image at the start would identify the original reel
    that the film was wound onto. Maybe it has more to do with tracablity - what
    time period the reel was used over, what lab processed it, etc.

    Yes, but the ones I looked at had extra boxes. For example, one had...

    --------------------------------------
    Prod. No.
    Scene Take Roll
    Date Sound
    Prod. Co.
    Director
    Cameraman

    Yup. I guess I'm trying to work out what information might be useful to me.
    So far, I've got...

    Production
    Scene Shot Take
    Location

    I suppose date would be a good idea, and maybe time of day (interested in
    how shots look when done at different times of day). Aye, it looks like
    'what, where, and when' are what I might want to know after the fact...

    But, if you might be using the tape to record another project
    *before* the other(s) have been transferred to the computer a
    clapperboard (or even a chalk-board [1]) can be useful to permanently
    make which shots belong to which project.

    [1] VT doesn't *normally* need a sound marker (clap) now, unless you
    need to sync two or more independent cameras in post.

    Yup. I'd dedicate a tape/tapes to a specific project and use others if I was
    doing something else as well.

    Some audio will very likely be recorded on a minidisk (the location is
    permanently windy and the in-camera sound is useless).

    If you need to sync 2 or more cameras that don't have synchronous timecode
    (broadcast cameras can sync their timecode with a BNC-BNC lead) a simple
    clap of the hands will do. With your palms horizontal make sure both cameras
    are running and can clearly see your hands and do one clap - it's as good as
    a clapperboard.

    Also, if your software can show the audio waveform of each camera track you
    can visually sync using that,
