Does anyone know where the A to D converters in digital video stuff
such as MiniDV, Digital8 and DVD run out of 1's and clip the signal?
Does anything bad happen when it does, such as bearding or losing sync?
This could happen in average use with impedance mismatch, maladjusted
camera clipping
point, etc.
I have seen consumer VHS machines that put out about 1.25 volts of
video, even when sync level is about normal. Presumably if digital
machines are designed to accept this (so the public can convert their
home tapies to DVD), then this would be
about the limit. I'm just wondering how close to clipping level normal
video would be. Also if I change the white clip point in a video camera
can I get a bit more dynamic range out of it (for consumer/industrial
not broadcast) without blowing anything up. Thanks.
