e Panasonic DVX100 was the rst prosumer camera to provide 24p and 30p progressive scan. Today, many

video cameras oﬀer a progressive scan option. Progressive scan oﬀers an image that is well suited for web video

and for display on computer monitors and at-screen displays.

Resolution. e amount of detail in an image. Higher resolution equals more detail. Also used to describe the

size of an image, usually in pixels, e.g. a high denition video frame consists of 1920 x 1080 pixels.

Single system sound. A method of recording sound and picture on the same device, typically this is the way it’s

done in video production. See double system sound.

Slate. 1. A device used to place an identier in front of the camera at the beginning of a take. When shooting

double system sound, the clapping motion and the clapping sound is used to synchronize the audio to the

picture in post production. 2. A shot or portion of a shot in which a slate or other identifying information

appears. Often master tapes will include a slate and countdown prior to the start of the show.

Stock footage. Motion picture footage from previously existing lms, led in lm libraries or archives, which is

incorporated into a new lm, usually to provide scenic background or for stock situations and settings, such as

war scenes or foreign locations. See compilation lm.

Synchronous sound (sync sound). 1. Recording sound in synchronization with recording image. Can be single

or double system. In single system sound recording the camera records sound and image, with double system

sound recording, the camera is used to record images and a separate sound recorder is used to record sound. 2.

Sound whose source is apparent and matches the action in a scene. See non-synchronous sound.

Terabyte. One trillion bytes. A two hour high-denition movie at a resolution of 1920 x 1280 would take

about one terabyte to store in an uncompressed format. Acquisition formats like HDV involve signicant levels

of compression in order to reduce the data required to store video.

Time code. 1. A time reference used to identify each frame of video, typically written or displayed as

“02:23:43:02” designating hours : minutes : seconds : frames. A semi-colon between the seconds and frames

typically indicates drop-frame time code (in which some numbers are skipped in order to align time code with

real time).

TV Safe. e area of the video image which will normally appear on a standard home television set. Due to the

design of CRT monitors, they over-scan the image, which means that the overshoot the edge of the tube, so you

can’t be sure that something that appears in the frame will actually be seen by “viewers at home” so it has

become standard to keep titles within an area called “title safe” and the rest of the action within “action save.”

Non-linear editing system and DVD authoring systems have guidelines you can turn on and oﬀ to see these

margins. Some LCD displays overscan the video so this is not a thing of the past.

USB (Universal Serial Bus). An interconnect standard used to connect computers, hard drives, cameras,

scanners, printers, etc. USB (a.k.a. USB 1.0) is a pretty slow standard, USB 2.0 (a.k.a. fast USB) is pretty fast

and is widely used for connecting cameras and external hard drives to a computer. Even though USB 2.0

appears on paper to be faster than FireWire, the manner in which FireWire is implemented makes it a faster

interface and thus FireWire, especially FireWire 800 is favored by video editors for interconnecting computers

to external hard drives.

Widescreen. A general term for presentation using a screen with an aspect ratio greater than 1.33:1 (4x3).
