PIP - Abbreviation for Picture in a Picture, a video effect which places several complete images on the screen at the same time.

Pixel - A single picture element. The smallest element in a graphic image. Pixels are combined with other pixels to make up a graphic image. Picture quality increases as the number of pixels increase in a measured area of an image.

Point - A standard measurement unit for type sizes. One point equals approximately 1/72 of an inch.

point-of-view shot (POV) - Shot perspective whereby the video camera assumes a subject's view and thus viewers see what the subject sees.

Prime Lens - A prime lens is one with a single focal length, wide, normal or telephoto, as opposed to a zoom lens which has a variable focal length. They often come in a set of different focal lengths. Prime lenses tend to be sharper, faster and will often focus closer than zoom lenses.

Primary source clip - A source clip that has media attached to it. The original source clip from which secondary source clips and reference clips are created.

Preroll - Preroll is extra time at the beginning of a sound take to accommodate the slow lock-up time of some post production time code devices.

Pull Down - A transfer of sound slowed down from film speed, 24 film frames per second, to video speed, 29.97 video frames per second, which is the equivalent of 23.98 film frames per second. This must be done to line it up with a video transfer of picture when transferring sync sound to video.


Pull Up - This term can be a little confusing since it has three meanings that both apply to sound. (1) The process of offsetting the sound 26 frames ahead of picture when making a print. (2) Pull Ups, as a noun, are transfers of the first 26 frames of sound from a reel that are spliced onto the outgoing sound of the previous reel so that sound is not lost when the film is printed with the sound pulled up, since 26 frames of sound are cut off when reels are joined. (3) A transfer of the sound from a video, sped up from video speed, 29.97 video frames per second, which is the equivalent of 23.98 film frames per second, to film speed, 24 film frames per second. This must be done when the optical track is made after having mixed in video.


PZR filter - A filter that enables the rotation of clip frames around any of three axes, the positioning of a frame in any of three dimensions and the control of the point of view through perspective adjustments.
