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.=20 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.=20 Jack Tunnicliffe Java Post Production On Apr 16, 2013, at 10:56 AM, "Sering, Joselito (HQP)" = wrote: > Hello all, >=20 > I was wondering if anyone has any advice on eliminating or reducing = video moir=E9 effectively on footage with subjects shot in front of = green screen like plugins or masking techniques.
