We did a test shoot yesterday for a project that will involve shooting lots of people using computers. We shot a RED and Sony F35. We really want to use the RED for this project, but every time a computer screen is in frame we get a heavy moire pattern on the screens with the RED. The F35 gets it as well, but it isn't nearly as severe. We tried to use various lens filtration to no avail, we were partly hoping when we projected the footage we wouldn't see it, and although projecting the footage on a large screen did help, it was still very severe. The only fixes we were able to come up with is not to shoot the screens in critical focus, or to skew the camera on a tango head and shoot the screen a little dutch. Obviously neither of these solutions are ideal.
We also tried many blur filters and post tricks, once in FCP also to no avail.
We shot at the RED at 4k and converted the files to uncompressed 4:2:2, 10 bit 1920x1080 and are using them at that resolution in FCP.
Has anyone else encountered this and is there any know work around, either something we can do on set or a special post filter to fix this problem? Any help would be greatly appreciated.
