Here are a few videos of what I've been up to this month in motion graphics.
Planet Earth - Rapture Effect
Who doesn't want to take pictures from outer space. Concept of this clip: the Earth in orbit just before the rapture; second coming of Christ.
Identity - Triple 16:9 Countdown
Countdown video I got commissioned to make for a local student ministry. It's themed for their fall retreat. The format is for a triple 16:9 side-by-side projection setup.
3D Camera Animation
Here's an advertisement or introduction concept. I really like the vibe of animating the camera around stills in 3-D space. I think it's a fresher perspective in collages.
Particle Generator - "Explosion"
Here's an example of a particle effect. The colors and intensity can be changed to give the effect of an actual explosion. Pretty cool, might want to do a comet title template with this; mimic the traditional "The More you Know" commercial.

Sound Waves: "In the Beginning..."
Dim the lights and grab a bowl of popcorn for this classic film on Sound Waves. This is a great explanation of where sound comes from. I took the liberty of typing up a short article to go along with the video.
Where does sound come from?
One complete complete compression and rarefaction defines a cycle. The length of time it takes to complete a cycle is the wavelength. This unit of time is measure in Hertz, Hz. The shorter wavelength is faster and higher in pitch. The longer wavelengths take longer and are lower in pitch.
Science of Sound
So why is the science of sound waves important for a sound guy to know, will it ever get used? The answer is yes. Microphones, mixers, speakers ( just to name a few tools ) are all used to capture, manipulate, and reproduce sound. So understanding the basic science they are built on will benefit your ability to use them well.
If this topic interest you, check out this book; Modern Recording Techniques. It's been the standard introduction to understanding sound and recording for years.
Where does sound come from?
Sound waves
are audible vibrations in the air. Just like a rock thrown into water
will produce a ripple, when you strike an object that’s in contact with
air it will produce sound. The pushing up of the wave is called compression and downward pull is rarefaction.
One complete complete compression and rarefaction defines a cycle. The length of time it takes to complete a cycle is the wavelength. This unit of time is measure in Hertz, Hz. The shorter wavelength is faster and higher in pitch. The longer wavelengths take longer and are lower in pitch.
[For
example, 5,000Hz sounds much higher than 50Hz. This is like comparing a
bee buzzing passed your ear to a semi-truck passing by you while you’re
walking down the street. The bee is producing higher frequencies,
whereas the semi-truck is producing lower frequencies; your soiled pants
in both situations is just a coincidence.]
Characteristics of Sound
Cycle - one complete push and pull of air
Wavelength - the length of a cycle
Hertz (Hz) - time it take to complete a cycle
Frequency - number of cycles completed in 1 sec *measured in Hertz (Hz)
Phase - Constructive or Deconstructive “combination” of wave forms.
Amplitude - Loudness *measured in decibels
Timbre - variations in a sound wave that make it sound unique.
