sound effects program for video editing?

    When editing a video it can be useful to add sound effects in real
    time while watching the video.
    I was wondering if there was a program that allows you to assign
    sounds to certain keys on the keyboard such as a car horn, etc. When
    playing back the video it would be easier to press a key on the
    keyboard and have the sound recorded on a audio track of the video.

    Does anyone know of a program that would store sound from wav or mp3
    files to certain keys on the keyboard for short sound effects?
    It should walk with the narration track in the timeline as sounds can
    be recorded in real time.

    Far as I know there isn't a video editor that allows sound effects to
    be activated by pressinf certain keys on the keyboard.

  2. Your probably correct, as there is no program like this..

    However, a more important question would be, "..why?"

    Even if there were a way to place them in by tapping your keyboard,
    there's no way they are going to line up exactly where you need them.
    While watching the video, your brain has to signal your thought process
    that it's time to add a sound, then your thought process has to think
    about what key to hit, then your brain has to signal your hand, and then
    it takes milliseconds for the finger to come down, and a couple of
    milliseconds for the computer to place the actual sound on it.. :)

    I recently worked on a short where there was over 130 sound effects
    (more than keys on a keyboard I might add), and it was a painstaking
    process to go over the time line and adjust each sound moving it over
    frames at a time, until it sounded right. So, adding sound in, is more
    of a very fine tuning process if you ask me.

    Thanks for your feedback Richard.
    I was thinking of sound effects that don't need exact timing such as a
    car horn sounding as a car passes by.
    If needed then the sounds could be lined up to match the picture after
    the sounds have been put on he sound track.

    Like video games timing comes with practice.

  4. No video editing app I know will do that. You can, however, set
    markers where you want the sound effects, then after all are set, put
    the files in place there.

    If you have an MIDI/audio sequencing program like Sonar which will
    load AVI files, you can use the MIDI synth (and possibly the MIDI
    keyboard -- there are utils to use a PC keyboard as MIDI input) to
    generate sound effects. While you're at it, you can also do the music
    scoring too ;-)

    One issue with any "real time" recording is that most video editors
    grab much of the system resources, and may not allow for any recording
    -- or live commands of any kind -- while the video mix plays back.
    Pushing out several audio and video streams with effects and such uses
    a lot of CPU time. It is a bit much to expect it to allow any other
    app/plugin to interact with its timeline live, in real time.

    An audio program, though, can do the trick -- playing back one video
    stream while recording (no video effects), especially with just a
    small window for output, wouldn't be a big deal.

  5. Greetings Brian,

    I thought about this some more.. The only thing that I can think of
    would be to set up a complex set of systems where you have one system
    playing the movie, and another system capturing the sound. Then plug in
    a sound effects mixer between the two systems.

    Something like this:

    Then once your done "dubbing" the system, simply take the new sound
    file, and exchange it and marry it to the old video. You can do this
    with VirtualDub, ect.

    The systems can be two separate computers, or a video playback (DVD
    player) and a computer. or..

    Of coarse this could get really complex, and ugly. :)

    This is easy to do and is done quite often.

    you use a MIDI keyboard and a hardware or software sampler. Load in your
    samples, assigne them to keys and play away..

    Many editors will record at least 1 track while you are playing back in
    the timeline.

    You can record right into the NLE or make a AVI or QT file of your movie
    and play it in the audio sequencing app llike ProTools, Nuendo.. etc.. In
    this app you can control your sampler, MIDI and record audio to picture.

    The key is that the samples are triggered through MIDI. Record either in
    the NLE or your audio app.

    or use a sampler
    or use ProTools, Nuendo, Sonar.. etc..

    This is done all the time.

  8. ProTools lets you push a button adding in sounds while its playing realtime?

    Haven't tried Protools, for some odd reason, I must be the only one who
    can't install it on my PC or Mac?

    Any audio recorder will record samplers. You can either use a hardware
    sampler or a plugin sampler.
    nappy, Jun 2, 2004
  10. Yeah.. but I suspected that it's not the ProTools itself that lets you
    set up keys on your keyboard to use as "hot keys" for sound. ProTools is
    only used as the means to record a new track with the new sounds.
