I'm sure this topic has been covered ad nauseum, but 20 minutes of searches on this forum and lots of "Googling" have left me without a satisfactory answer to this basic question.
I would like to film someone watching a B&W TV and use some of the TV footage in the shot. I don't want to green screen the TV footage, because the light from the TV is important to the shot.
I know on features you would simply hire a "24fps playback guy" and he would use a "sync box", but what exactly is the technology?
I would theoretically be shooting with a 16mm sync camera (not sure of model, it would be a rental) and ideally would like to use a large LCD monitor dressed as a "TV" playing back 24P footage from FCP. Is this possible, and, if so, how exactly does the synchronization work??
Also, if this is possible, I would also like to figure out a system to playback the video at 48fps and shoot a few setups at 48fps so the video is real-time and the people watching are in slo-mo (abstract indie music video).
Any guidance would be much appreciated, as would any links to previous discussions of this topic.
