MusicalLighting

Overview

My project is a "style" in the muvee Reveal movie editing program that changes lighting effects as the music in the movie changes. The user can choose the type of lighting effect to either be changed as either transparent or colored lighting. There is also an option to use a random transition effect (out of 4 possible transitions) between each slide.

Concepts Demonstrated

• Tail recursion - used to divide each segment of the movie the desired amount of times.
• Data abstraction - used to access the values of colors for lighting effects.
• Higher order procedures - used to take in a function of time to determine lighting values at each part of the movie.
• List building - used to create list of arguments to pass for the lighting effects.

External Technology

This project adds a "style" to the muvee Reveal software. It utilizes the muSE (muvee Symbolic Expressions) Scheme dialect that comes with muvee Reveal for music, lighting, and transition effects.

Innovation

muvee Reveal provides styles that respond to music by changing the pace, transitions, and various other effects, but none that change the lighting in response to music. I don't know of any other movie editing software that allows effects to be controlled by the music like in muvee Reveal. Since muvee Reveal is mostly based in Scheme it was easy to connect with using Scheme.

Additional Remarks

The transition effects only seem to work with the transparent lighting. Only the fade-out transition works when using the color lighting. Otherwise, the style seems to work just as planned, though at times the lighting effects seem a bit delayed with the music. I think this is just a problem with the software and not the actual style. The documentation for muSE/muvee styles was very helpful.
