    hi

    I have a panasonic mini dv, and i want to record indoors, music
    and conversation. which will produce the best sound 12 or 16 bit?
    what is the difference?

    Also i use a UV filter outdoors, and for sake of the lens
    never take it off. if i am recording indoors under artificial
    light, will leaving it on affect the quality of the video, like
    reduce light etc?

    thanks

  3. 16 bit will in theory produce better quality, but 12 bit allows dubbing
    an extra pair of audio channels onto the footage later without
    disturbing the original sound track. Some cameras give the choice
    between 2x16 bit channels or 4x12 bit channels at record time.

    If you're using the camera microphones, they're the limiting factor, for
    a number of reasons.
    No. They make a difference of less than 1/3rd of a stop.

    However, make sure both faces of the filter and the front of the lens
    are *absolutely* pristine, as the slightest mark will show up if there's
    stray light hitting it from outside the camera's field of view,
    especially if there is more than one source of light. Also watch out for
    mixed daylight & artificial light, as it's virtually impossible to
    correct the colours after the fact.

  4. It is more than theory. Even non-experts can readily hear the
    difference between 12-bit and 16-bit.
    Is there ANY current equipment that supports that feature?
    Was there ever any?
    Even with the universally crummy built-in microphones most
    people can hear the difference between 12-bit and 16-bit.

  5. I've tried both on a Panasonic NV-DS30, & the handling & mechanical
    noise is, indeed, recorded in higher quality, which is why I said the
    camera microphone is the limiting factor. With an external microphone,
    16 bit is noticeably superior.
    I could have sworn my NV-DS30 did, but re-reading the manual, I'm wrong.

    Sony say this one:-

    Sony Handycam DCR-HC1000

    Will record 4 channel surround sound with a special microphone.

    Shown as obsolete, though.
    It's that long since I used mine for any serious sound recording, I'll
    bow to your experience.
