feedback
A loud squeal or howl caused when the sound from a loudspeaker is picked up by a nearby microphone and reamplified. Also caused when the output of a tape recorder is fed back into the record circuit.
field
One-half of the scan lines in an interlaced video frame. In most systems, the odd-numbered lines form one field, and the even-numbered lines form the second. NTSC video contains approximately 60 fields (30 frames) per second, and PAL video contains 50 fields (25 frames) per second.
file system
A way of organizing directories and files on a disk drive, such as FAT or NTFS for Windows computers.
See also format.
filler clip
A segment of a sequence that contains no audio or video information. Filler can be added to the Source monitor (or pop-up monitor) and edited into a sequence.
See also filler proxy.
filler proxy
The result of a composition specifying media to be played for the filler clips in each track.
film timecode
Timecode added to the film negative during the film shoot via a film timecode generator. Film timecode numbers are synced to the film key numbers on the dailies during the telecine transfer process. A special key link reader is required for viewing the film timecode.
flash frame
After a long, complex piece is edited, small bits of video might be accidentally left in a sequence. When the Timeline is zoomed to 100ápercent, these small, unwanted pieces might not be visible. An editor can use the Find Flash Frame command to find these bits.
foley
The background sounds added during audio sweetening to increase realism.
format
To prepare a disk drive or floppy disk for use. For Windows computers, you format a disk drive by copying a file system (either FAT or NTFS) to the drive.
formatting
The transfer and editing of material to form a complete program, including any of the following: countdown, test patterns, bars and tone, titles, credits, logos, space for commercial, and so forth.
fps
Frames per second. A measure of the film or video display rates
(NTSC = 30áfps; PAL = 25áfps; SECAM = 25áfps; Film = 24áfps).
frame
One complete video picture. A frame contains two video fields, scanned at the NTSC rate of approximately 30áfps or the PAL rate of 25áfps.
frame offset
A way of indicating a particular frame within the group of frames identified by the edge number on a piece of film. For example, a frame offset of +12 indicates the twelfth frame from the frame marked by the edgecode.
frame pulse
A pulse superimposed on the control track signal. Frame pulses are used to identify video track locations containing vertical sync pulses.
frame synchronizer
A device that allows a nonsynchronous video source, such as a satellite or microwave feed, to be used in a timed-video environment by capturing entire frames.
freeze frame
A video effect that appears to stop the action. Freeze frames can be created during recording, digitizing, or during an editing session. Compositions can create this effect by using a track repeat object that can specify the display of a single frame for a period of time.
front porch
The portion of the composite video signal that starts at the trailing of the picture information and ends at the leading edge of the horizontal sync.
