We are setting up a big cellar as a studio in which we will shoot with a green screen. At this point we have two solutions:
What do you think is the most practical?
Is there a risk to have chroma-key issues with the curtain? If we opt for the paint, how often should we expect to have to refresh the paint?
Thank you for your help!
Practical or most effective?
Green Screen work demands the following optimazation points to have it be effective.
Additionally, to help avoid hot spots, plan on a fresh drywall/plasterboard for that wall and when fixing, ensure sunk and smooth plastered nails. This will help you get a consistent surface for the green.
A curtain if it can be expanded to be absolutely flat with out any wrinkles might work, but I think this will be very troublesome.
Painting the wall with the appropriate paint would be more effective.
When to repaint?
Establish a base-line video test, that is repeatable, same lights, same object(s), same camera. Run this in your post production chroma-key video track before each production use, and it should be obvious if the paint needs to be refreshed.
