field
Half of an interlaced video frame consisting of the odd or the even scan lines.

FireWire
Apple's trademark name for its implementation of the IEEE 1394 protocol used to connect external hard drives, cameras, and other digital devices to computers. It provides a fast interface to move large video and audio files to the computer's hard drive. FireWire exists as two standards: FireWire 400 and FireWire 800. FireWire 800 has twice the bandwidth of the traditional FireWire 400 and uses a different hardware connector.
frame
A single still image from either video or film. For video, each frame is made up of two interlaced fields.

frame blending
A process of inserting blended frames in place of frames that have been duplicated in clips with slow motion, to make them play back more smoothly.
frame rate
The speed at which the individual images making up a moving sequence play back. It's stated in terms of frames per second (fps). Film in 16mm or 35mm is usually shot at 24 fps; NTSC video is 29.97 fps; PAL video is 25 fps. High definition (HD) can have several different frame rates.
framing
Composing a shot for the best presentation of the subject, taking into consideration the size of the subject in the frame and how it is positioned.
frequency
The number of times a sound or signal vibrates each second, measured in cycles per second, or hertz (Hz). Audio recordings are made up of a vast collection of waveforms, using many different frequencies of sound. Each frequency in a recording is associated with an audio pitch. The frequencies of an audio recording can be changed to disguise a voice or to clean up an unwanted noise.
