Specifications

A Digital Video Primer

Preproduction: e planning phase of a lm or video project, usually completed prior to com-

mencing production.

Previsualization: A method of communicating a project concept by creating storyboards or

rough animations.

Print to tape: A command for exporting a digital video le for recording onto videotape.

Production: e phase of a lm or video project that includes shooting or recording raw footage.

Program monitor: Window on the Adobe Premiere Pro interface that displays the edited program.

Progressive display: A method for displaying sequential images, such as the frames comprising

lm or video, whereby the entire image is shown at once; contrast with interlacing.

Project: File with all information pertaining to a job, including settings and source material.

Prosumer: Denes a market segment for video equipment and soware, comprising serious hob-

byists and those whose primary profession is not video production.

Pulldown: Technique used during the telecine process in which the 24 fps rate of lm is converted

to a video frame rate: 29.97 fps for NTSC; 25 fps for PAL and SECAM.

QuickTime: A multiplatform, industry-standard, multimedia soware architecture developed by

Apple and used by soware developers, hardware manufacturers, and content creators to author

and publish synchronized graphics, sound, video, text, music, VR, and 3D media.

RAID: Redundant array of independent disks, a digital data storage subsystem composed of mul-

tiple hard disks that are handled as a single volume in a computer.

RCA connector: A connector typically used for cabling in both audio and video applications.

RealMedia: Format designed specically for the web by RealNetworks, featuring streaming and

low data-rate compression options; works with or without a RealMedia server.

Real-time: In an NLE, refers to the processing of eects and transitions, so that playback of an

edit is continuous and there is no wait for rendering or processing.

Rendering: e processing of digital media into a nal form.

Resolution: e amount of information in each frame of video, normally represented for digital

displays by the number of horizontal pixels times the number of vertical pixels (such as 720 x 480);

for television, by the number of vertical scan lines (for example, 525 for NTSC). All other things

being equal, a higher resolution will result in a better quality image.

RGB: Red, green, blue, a way of describing the color of a pixel using the three primary colors (in

the additive color system).

Ripple edit: Automatic forward or backward movement of program material in relationship to an

inserted or extracted clip, or to a change in the duration of a clip.

Rolling edit: Automatic change in the duration of a program when a clip is inserted or extracted,

or when the duration of a clip is altered.

Rolling title: Text that moves vertically up or down across the screen.

Rotoscoping: Painting on individual frames over a series of frames to create an animation or to

remove unwanted details in lm or video footage.

Rough cut: A preliminary version of a video edit, oen assembled from lower quality clips than

those used for the nal cut. Rough cuts are created to communicate an editorial concept, or

provide a guide for the nal edit.

Sample rate: In digital audio, the number of times per second the amplitude of the analog waveform is

measured and converted to a binary number; the higher the number, the better the sound quality.

SAN: Storage area network, a data storage subsystem that can provide terabytes of capacity and

be simultaneously accessed by multiple users. A SAN may be JBOD (just a bunch of disks) or

composed of multiple RAIDs.
