I lost my first response. Sheesh, I've been using computers since the early 1990's and now I'm losing my mind. ROFL.
SOMEtimes the problem with grainy images or videos is due to low light, but that isn't the case this time, at least not for me. The light is just fine, but the subject image (in this case, me) is out of focus. Occasionally the background is in focus but the subject is always blurry.
Maybe I'll make an appointment with the GeekBar or whatever it's called, when I have a spare day to spend. In the meantime, it's just videos to my grandson (almost 5 years old) and granddaughter (almost 2 years old) so they aren't nearly as critical as I am.
Thanks for the responses.
