by Diggersworld.com Programming the Light Show: Twenty three light controllers (sold by Light-O-Rama) control this years light show.  Each controller can control 16 sections of light up to 8A per channel or 30A per controller.  A section of light, for example, may be one red string of lights on the tall 3D trees, one of the dancing trees, or one small segment on the leaping arches.  We are slowly changing to more LEDs to brighten parts of the show and reduce the amount of burned out bulbs over the month that the show takes place. The image below is the LOR controller.  Each controller is placed in a weatherproof metal enclosure designed for commercial applications. A central ‘Director’ is the hardware that plays light sequences off a SD memory card at a predetermined schedule (5-midnight).  The director sends commands to each light controller at precise times - up to 20 times per second. The commands tell the LOR controller to turn on or off, fade up or down, blink randomly, and shimmer (repeat a very fast on/off) at any time during a song.  At the same time, the director plays the audio which is sent to a small FM transmitter so visitors can listen to the music in the comfort of their car. The difficult part is deciding when to send the command to the lights.  The software package that assists this is also from Light-O-Rama.  Each song is listened to in small sections often at 1/2 speed and then a designer decides what the display should look like at that point in time. The image below is the LOR programming software showing a sequenced 7-second section of Santa Claus is Coming to Town.  Only a small section of the total number of channels are displayed.  The image on the right is an animated picture that provides an idea of what the display will look like as the song plays.   Assembling the Audio and Voices: Each riddle is recorded about 4 times so we can choose the best one to use in the show.  Once the best voice is selected, the editing begins.  The voices are raised in pitch, reverb is added and then compressed to make the voice stand out.  Laughing is added after each joke and finally music is added to the background.  Below is a picture of the sound editor with the introduction being edited.  This same editor is used to shorten some of the songs to fit within the show. Creating the videos: The videos are taken very late at night to minimize other car headlights.  A Flip UltraHD is used for the wide view.  For the chipmunk closeup, a SLR camera with telephoto lens was used in HD video mode.  No sound is recorded at that time.  Once the video is done, it is imported into a video editing program and then the soundtrack is added, the opening title is added and the picture is adjusted for best look.  It is then rendered into a smaller size video that can be viewed on the website.  The chipmunk video required additional work to zoom in on the faces.  There are actually two videos that are merged together: the wide view of the show and a close up of the chipmunks.
