Moiré removal on one color fabric using color layer mode

I did a shoot with my new BMCC a couple of days ago, and the camera's performance was solid. Except for one shot with a certain factory suit fabric that gave a lot of moiré pattern. To level up with every good shot, I decided to work with the moiré more to get rid of it. I found this tutorial a year ago:



I used Keylight to get a mask of the fabric, since the fabric was all blue. I then added a new solid (using Keylight's mask) with the color of the fabric and color layer mode. In a five minutes of work the color of the moiré was gone! Only thing remained was the pattern. I added a new white solid with layer mode as color. Then I used a hue/saturation effect on the original footage to phase-out the moiré using hue and saturation sliders. After 10 minutes of work I got rid of the moire more than half (not just one frame but the whole shot)!

In stills the phase stays roughly the same, but in video it changes when the lighting or direction of the fabric changes. Maybe by using keyframes on the hue/saturation effect would work, but just this really did the trick in salvaging the footage.

Sounds interesting...can you share a before/after clip with us?

There are some glitches, but it's a rough test.

That works really well actually! Thanks for posting
