    anyone know of any products that will allow me to convert a 'video'
    that was shot on a cam corder
    using 'no light' (rather than the full color process) and improve the
    quality of the video, add color and improve the audio?

    part of it is in color and part was done with that 'green' night
    vision looking process.

    Perhaps some of the black and white to color filters can do it. I would
    imagine that even then you would have to apply significant color
    correction to it as well. Overall a very laborious process.

    Of course your next question will be - 'what software do I use?' I've
    never used any. Well, I use Vegas video, and I can visualize that how I
    might use the secondary color correction to try and match portions of
    the green video to the color part. Still. I don't know if you will get
    much satisfaction. The nightvison stuff I recall has far less shading
    difference than a black and white.

  3. You could use the same techniques they use to "colorize"
    old black & white Hollywood movies. Don't get your hopes
    up for either decent video or audio "improvement".

    Which is what I thought to begin with, but then I thought about how
    monotone and uniform the green is in those night vision shots. It might
    be the devils own job trying to get any filters to make consistent
    decisions based on greenscale? shading.

  5. Don't let the green color fool you. You have a black & white picture
    that just happens to be tinted green because of a technical quirk.
    You would have to remove the green anyway (make it B&W) to
    attempt to kludge anything that resembles a real-color image.
    There is no useful information in the green tint.

    I wouldn't even try to 'improve' the colour rather go the other way and
    either turn it sepia or black and white. Trying to add colour where there is
    none only brings up noise and other artefacts unless you have access to
    Hollywood style upmarket software. With the sound you could run it through
    CoolEditPro or Adobe Audition, etc and apply some of the filters available.
    You don't describe what's wrong with the sound? Generally with sound , wind
    noise, handling noise and off mic is common. Reducing the bass response via
    a high pass filter can subjectively improve dialog

    After the conversion though will the footage have enough subtlety in the
    greyscale to allow for more than some broad color decisions. Really, I'm
    just musing out loud cause I don't know. Never tried it. I might give it
    a go and see what success may or may not be had. Try the same steps and
    process with the same subjects show with the same camera under same
    light in B&W also and compare.

    I seriously doubt it. You could take a typical frame
    and try it. That should be enough to dissuade you
    from thinking you can make anything out of noisy
    monochrome video. Of course, it depends on what
    your expectations are (?)

    Thats kinda what I figured really. That green stuff is really pretty
    flat and noisy.
