Frame Rate
The frame rate of any motion picture, whether film or video, defines how often pictures
are taken per second. The higher the frame rate, the more accurately you capture
moments in time and reduce flicker during playback. To achieve double the perceived
frame rate (flicker), film projectors actually double or triple the shutter speed, even
though the same frame is repeated two or three times, respectively. This is because
a faster flicker creates more convincing motion. Video uses a similar, although more
complicated, technique called interlacing. For more information about interlacing, see
the next section, “
Scanning Method
.” For more details about frame rate, see
Appendix B, “
Frame Rate and Timecode
,” on page 405.
