Joe:

 

Are you talking about a moire in your = subjects or foreground? Often there is a moire or pattern noise caused = by large sensor cameras because of the enormous resolution they have = which is often more than you need for an HD = production. 

 

Yesterday I was working on a project shot on = Epic 5K and a sweater a woman was wearing that had a certain patter that = caused a moire. Often the moire shows up at a certain focal length where = the pixels on the sensor match up with the pattern so zooming in our out with the camera will affect how the patterns = causes noise, just like a photograph in AE that is made up of dots... at = a certain scale the photo goes nuts.

 

Anyway, my fix yesterday was to change the = resolution of the image and presto the moire was gone. Instead of using = the full 5K image for the shot I dumbed down the image to half = resolution, still more than enough for HD television and the moire disappeared. Now I did this in Davinci Resolve where I have quick = access to Raw controls and resolution of the image but the same could be = done in AE.

 

If this doesn't work I usually grab onto the = area in question, again usually in a colour correction application like = Resolve and do a slight blur of the pattern that is causing a = moire.
