I am looking to shoot a scene where a person is going to be watching TV and I'd like to understand all the available options when it comes to fighting or avoiding flickering. Ideally I'd like the TV to be an old CRT one, in which case is there any other way apart from screen replacement? If I go down this route of screen replacement is the green screen the best way to do it? Are the results believable?
I'd like to understand other options too even if it's a projector (doubt it) or a modern LED display that will do it.
