Rear Projection Flickering

[James Harding]

Hi everyone,

 

I am about to film a hitchcock style film this week which involves a rear projection in a studio. I am currently using a Panasonic PT-D3500E projector and the Arri D21 with a shutter angle of 180 degrees. I have noticed in tests that there is a severe flickering/phasing issue that I would like to fix. Does anyone know how to get around this, do I need to experiment with different shutter angles or perhaps a different projector, ours is a 1 chip DLP projector, I wonder if LCD or 3 chip DLP would help?

 

Thank you

 

James
