Frame rate: The frame rate defines how many frames
of a video sequence are played in one second. The
frame rate for  NTSC video is 30 frames per second.
The frame rate for  PAL video is 25 frames per
second.
Frame size: The maximum size for displaying image
data in a video or animation sequence. If an image
intended for the sequence is larger than the frame size,
it must be cropped or scaled to fit.
Frequency: The number of repetitions in a periodic
process (like a sound wave or an alternating voltage)
per unit of time. Usually measured in repetitions per
second, or Hertz (Hz).
