Beamer RGB colors

[Polaroid22]

Hello,


I am shooting something that is projected with a beamer, but I see these RGB colors. How Can I fix this? (beamer is 60hz) A7S II is on NTSC 24fps 40 shutterspeed(to counter the moving lines on the screen).

Any idea how to fix this?


thanks!

Update:

It is called the rainbow effect. So I know what I am dealing with.
