Green/Blue TV Screen
Posted 18 March 2008 - 11:04 AM
1) Have a TV screen set on auxiliary or AV channel that will simply be a blue screen. My worry is that it will still flicker.
2) Have a video of a solid blue/green color playing on the TV running at 24fps. But will it flicker because it's still NTSC?
3) Have a blue or green mat over the TV screen. This would be what I'd do if the first two won't work.
Suggestions? Is there a fourth method?

Or if you use an LCD screen with a television facade over it then the blue output of the screen might work fine. I suppose even if you figured out how to balance the LCD color and brightness and therefore use the actual video during the shot, the odds that the timing will be right aren't that high.

You'll need to do a 4-point track in order to add your new image to the screen, so make sure all four corners are well-defined.
I gaffed a music video that used the corner tracking marks to add in the screen image. I had nothing to do with the FX, but I'm guessing they had to do some roto where subjects ovelapped the screen. In those cases I think a complete green screen material (with well defined corners) could have been more helpful.
