    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

    mike

    16 bit means that each sound sample has a fidelity of 65536 possible
    amplitude values. 12 bit means there are just 4096 possible amplitude
    values. Also, I have a sneaking suspicion that 12bit audio on DV is recorded
    at 32KHz instead of 48KHz, so as well as each sample having a limited amount
    of fidelity in its amplitude, it's also dropping fidelity through the loss
    of one third of the samples per second.

    The editing software I use seems to struggle with 32KHz, 12bit DV audio, so
    unless you have a good reason for using it, steer clear.

    We have ours on and off the stills camera all the time, and to someone like
    me, the difference isn't noticeable. They have earned their keep protecting
    the lens, though! I'd suggest that continually taking it on and off is
    likely to increase the chance of the camera being dropped, so it stays on
    all the time.
