"Grain" removal
on Mar 21, 2010 at 1:37:43 pm

I have a beautiful CU of lead actress with unfortunate "grain" resulting from the Letus lens system used on EX1 w/Nikkor lens not being on / vibrating---ground glass vibrates to "hide' its texture. So it's not really a video noise thing, but rather the actual ground glass surface texture. I have read other grain removal posts, but thought maybe there was some thing I might try .
Any plug ins ???

Grain & noise reduction plugins are designed to deal with moving grain, not the fixed stippling of the ground glass. You may try median filters, but expect this shot to require a lot of work for a marginal benefit.

OK makes sense, please explain median filters.

A median filter is a kind of blur. It looks for "median" values between pixels, and will smooth things out. If you have Shake or Nuke, you can use keys & roto mattes to isolate various areas to apply different levels of blur & median filters.
