Glossary: P
PAL
Phase Alternating Line. A color television standard used in many countries. PAL consists of 625 lines of information scanned at a rate of 25áfps.
See also NTSC, SECAM.
palette
A central location for user-selectable buttons, which you can map to various functions for ease of use. The Command palette houses all the user-selectable buttons that allow you to perform a wide range of commands with a single click of the mouse.
partition
A method of assigning disk space that creates two or more virtual disks from a single physical disk (similar to creating a directory).
patching
The routing of audio or video from one channel or track in the sequence to another.
pedestal
See setup.
points
The mark IN and mark OUT entered in the Timeline.
pop-up monitor
An ancillary monitor used to view and mark clips and sequences.
position bar
The horizontal rectangular area beneath the Source monitor, Record monitor, Playback monitor, Composer monitor, and Source pop-up monitor that contains the position indicator.
position indicator
A vertical blue line that moves in the position bar and in the Timeline to indicate the location of the frame displayed in the monitor.
postroll
A preset period of time during a preview when a clip will continue to play past the OUT point before stopping or rewinding.
precomputed media
A computed effect stored in a file and referenced by a composition or sequence. Applications can precompute effects that they cannot create during playback.
prelay
The phase of audio postproduction during which music, sound effects, dialog replacement, and announce tracks are added to the master multitrack before the final mix.
preroll
The process of rewinding videotapes to a predetermined cue point (for example, 6áseconds) so the tapes are stabilized and up to speed when they reach the selected edit point (during recording or digitizing of source material from a video deck).
preview
To rehearse an edit without actually performing (recording) it.
preview code
An additional reference numbering system, like key numbers, supported by FilmáComposer for comparing digital sequences with evolving work print versions using change lists.
primary color correction
Color correction that applies to every part of a video image, or to every part of a video image that falls within a defined luminance range.
See also secondary color correction.
print
A positive copy of the film negative produced in the laboratory.
See also answer print, release print, work print.
process shot
A shot photographed specifically to be part of a special effects composite.
Program side
In color correction, the second of two available levels of color adjustment. Corrections made on the Program side typically apply a final look to a finished sequence, for example, by fine-tuning the color values to enhance the mood of a dramatic program.
See also Source side.
progressive media
Media composed of single frames, each of which is vertically scanned as one pass.
project
A data device used to organize the work done on a program or series of programs. Bins, rundowns, and settings are organized in the Project window. The project bins contain all your clips, sequences, effects, and media file pointers.
Protection master
A copy (dub) of a master tape, usually made immediately after the master has been recorded. It is used as a backup if the master is damaged.
pulldown
A process in which extra fields are added or "pulled down" during the conversion of 24-fps material to 30-fps NTSC or 25-fps PAL videotape. This conversion can be a telecine film-to-tape transfer or a 24p high-definition (HD) downconversion. Special procedures are required when recording or digitizing to eliminate the extra pulldown fields and to achieve true 24-fps editing. (PAL video with pulldown is not currently supported in Avid editing systems.)
pulldown phase
In a project based on an NTSC 24-fps to 30-fps transfer, the video frame at which a master clip starts: A, B, X, C, or D. The pulldown phase represents the pulldown-to-timecode relationship. Also called pullin frame.
pullin
An Avid term that combines two words — pulldown and IN point. The pullin is the column where the user logs the pulldown phase of the start timecode as either A, B, X, C, or D. The user can modify this field before or after recording or digitizing.
pullout
An Avid term that combines two words — pulldown and OUT point. The pullout is the column where the user logs the pulldown relationship at the sync point of the OUT point (end timecode) as either A, B, C, or D. This field cannot be modified by the user and is calculated by the system based on the pullin and the duration of the clip.
