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
