Joe:

 

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

 

Yesterday I was working on a project shot on Epic 5K a= nd a sweater a woman was wearing that had a certain patter that caused a moi= re. Often the moire shows up at a certain focal length where the pixels on t= he sensor match up with the pattern so zooming in our out with the camera will affect how the patterns causes n= oise, just like a photograph in AE that is made up of dots... at a certain s= cale 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 im= age 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 acc= ess to Raw controls and resolution of the image but the same could be done i= n AE.

 

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