The minimum requirements are simply a screen, and a projector capable of displaying an image sufficiently bright for the given screen dimensions. Because the visuals are performed live during the performance, the conductor has no additional tasks and can focus entirely on the orchestra.
Since the visuals include night-time or space scenes, it is necessary for the concert hall to be made as dark as possible. This means the musicians must perform with the aid of music stand lights. A spotlight on the conductor is typically necessary for the musicians' benefit. It is recommended that the orchestra rehearse with stand lights and visuals at least once before the performance.
The video feed is supplied by a laptop computer that can output HDMI, DVI, and VGA signals.
The laptop and on-site choreographer need to be located in a position that has a clear view of the conductor. In practice, this can be anywhere in the hall, but the ideal location is on-stage.
While all the visuals are in high-definition (16:9 1080p) and an HD projector is preferred, in practice an HD projector not a requirement unless the screen is very large. However, increased projector brightness, resolution, and color fidelity significantly enhance the experience for the audience.
New for 2017: A choice of two synchronized DMX light show programs are now available for The Planets. The first adds simple color washes for each movement and occasional use of light effects. The second has numerous effects matched to the visuals and is suitable for immersive experiences where light fixtures are placed throughout the auditorium.
