Reducing moire on touch devices?

[Geronimo]

I've been shooting video of a number of touch devices (iPad, Surface, etc.) using Nikon and Canon HDSLRs, and the portion of the screen on these devices that is most in focus exhibits pretty bad moire pattern. (Example image attached) Does anyone have any tips or tricks (or know of a different camera) to use to lessen the moire, or negate it entirely?

Shoot with the screen off and insert it in post.

We're shooting actual touch demo videos, so we show the hand doing touch gestures and whatnot - it's not just a static image.

I feel your pain, we are having really good luck with C100.

If you must do this live, then you'll need to use another camera. Canon C100 to Ninja-2.

You could try the Mosiac anti-alasing filter, but I have no examples of this kind of shooting with it.

+1 for the Mosaic VAF.

You can also make it a little 'soft', if the focus is on the hand gesture and not the screen.

Every production I am on, almost always replaces screens in post.

Back in the olden days there were the sync problems with shooting TV screens due to the difference in frame rate, unless one changed the refresh rates on the TV's... now it's moire effects...

Thanks all for the feedback - will definitely be giving the Mosaic VAF a shot.
