Remote Mic with TM700

    My Audiotech wireless mic showed up today.

    It is mono mic with a stereo (1/8") out plug.

    What I would like is to have both the remote mic and some of the sound
    from the on camera mike.

    How to do this? I imagine that just plugging into the mike jack on the
    TM700 cuts off the internal mikes. Is this correct?

    Is there a way around that? What about the the other three channels? How
    do they work and just what is on them?

    Ideally I'd like to take this into Vegas and have control over the
    amount of ambient.

  2. I tell ya, I would much rather use a little digital recorder placed on the
    subject or wherever you want, than a wireless mike. No problems with
    interference or using up the camera's sound tracks, and you can mix it as
    desired in post. Probably cost less, too.

  3. Either the internal mic can be used (stereo or multi-channel,
    menu-selected), or the external mic works, but not both together.
    Either do what Gary suggested, synching the camera' audio with
    that of the external recorder during editing, or not, but the
    TM700 has no provision for directly mixing the internal mic's
    output with an external mic's output...

    I agree. But if a portable digital audio recorder is used you need a way to
    sync the sound of your portable recorder to the sound of your camera when
    editing as well as finding a audio clip to match the video clip. You could
    try using the time stamp on the video and the audio files. Yelling out the
    scene and take or the current time can help.

  5. Never EVER a problem, because there is always a spot or many spots in the
    scene where there is an obvious point to sync on. "Please be seated" in a
    wedding, beginning of music in a concert or play. If there was no such
    point, then sync wouldn't matter. I have never had to use a clap board for
    any purpose, and I have been shooting double system since the talkies.

    Obviously, once in the editing room, you fine sync using the waveforms under
    each other.

    Its only happened to me once when editing. I unlinked the audio and video
    tracks to do a few special effects such as freeze frame or slowing down a
    part of the video and did n't want to affect the audio track. For some
    reason the sound came out of sync with the picture and I tried to use mouth
    movement to sync the sound but its not as easy as it might seem to be.
    There may be times where you are recording at a distance (using the zoom)
    and have the portable recorder close to the source of the sound so the
    cameras microphone only gets a weak signal which can make syncing to the
    cameras audio difficult.

  7. True, but if you can't see it then neither can the audience. You can also
    just try and match gains and listen for echoes.

    As for syncing up sound to visuals using lip reading, I had to do that for
    many years in my film work, and we didn't have a "camera" track or video
    monitor to fall back on, nor did we use clap boards or anything else. The
    technique was to get it approximate by using the obvious visuals, such as
    this is where he started talking, and then "slip sync" in either direction
    until it hits. Sometimes it isn't real obvious which way to go if it is
    close, so you try both ways and see. But when it hits you know it!

    PS - I am new to Vegas, but I thought I spied a control near the bottom of
    the screen that sets speed of playback. That might cause some confusion at
    times. Am I right on that?
    Gary Eickmeier, Oct 28, 2012
  8. In many editors (I know you can do this in Vegas...;-), you can
    export an audio track with the audio amplified at a much higher
    level, import that track, easily synch it with the original (it
    will be the same length as the original), group it with the
    original track to use its more visible wave image as the guide,
    and when all is properly synched, you can either silence the new
    guide track, or ungroup it from the original track and dump it.

    I was using some special effects in vegas such as slowing down the video
    and suddenly found that a person was talking out of sync. I found it
    difficult to get him in sync. You think you have the person in sync but as
    you say when you play it back something does not feel right.

    If you have bits of silence in the audio track such as someone talking it's
    easier to do but if you have continuous music or some other background
    sound mixed in with the vocal then it can be more difficult. A person that
    does not speak clearly and does not have much mouth movement is also
    difficult to sync.

    Still I do like our suggestion
    Brian, Oct 30, 2012
  11. OK, here's another one: while taping someone talking or singing, throw
    a brick into the camera's field of view where you can simultaneously
    see their mouth and the brick hit the floor. It will then be EASY to
    synch the audio tracks while editing! 8^)

    Snap your fingers in front of the lens. Synch to when your middle finger
    hits the base of your thumb.

    This is a MUCH better method than mine! 8^)
    (But, unfortunately, I can't snap my fingers....)
    David Ruether, Oct 30, 2012
  14. The problem I see with your method is, what happens if I forget to take
    the brick along for the shoot?

    You could also take along a few marbles. They are easier to carry and
    less dangerous, but they will do the trick. Unfortunately, I've lost my

    I writing?!
    Sigh, similarly, I have also begun to "misplace" many of mine, too...8^)

  16. Hey - I've got an idea - get a clapboard!

    I was going to suggest that, but it is unfortunately considered too old
    timey to be considered by many. I carry in my kit a little clapboard about
    6 inches wide. Works a treat.

  18. What's wrong with a frog clicker?

    Hold it so it's easy to see the snap action.

    I'm thinking of making one from a small white board.
    However they tend to be old fashioned these days. A buzzer and a red light
    might be a better solution. The sound person presses a button and the
    camera sees the light and hears the buzzer.

    I think with processional recording a beep is generated on the sound track
    of the camera. Does anyone know more about this?
