Hello to all,

I need to shoot an LED TV, the content will be added in post production so it needs to be a clean Green for keying, however I did some tests and the Moire Patterns that appear are unbearable. Im shooting on the Red Dragon so it is not a compression issue. Any recommendations on how to deal with the problem? The patterns disappear the second it's slightly soft, but I rather keeping the television in focus.

Thanks!

J.

Instead of shooting the TV, why not cut and place a green screen inside the bezel?

In my reply in the thread on how screens in House of Cards, Social Network, Girl with Dragon Tattoo look so good

i posted a VFX reel of a guy who've worked on HoC and

the phone sequences show tracking of it is involved.

Doing a Roto out of the tracking is also easy.

 

However, somebody/something crossing the screen may involve less or more

delicate roto time. Hair anyone? :)

 

 

Best

 

Igor
