| N Hour Rate |
The length of time it takes to discharge a fully charged battery at a constant current. |
| Nanosecond (nsc) |
One billionth of a second. An indication of the precision required in the timing of video signals. |
| Natural Light |
Planetary illumination -- from sun, moon, stars -- be it indoors or out. Has higher color temperature than artificial light, and thus more bluish qualities. [See artificial light, color temperature.] |
| Neighborhood EV (nEV) |
An EV that is not for highway use because it operates below highway speeds. |
| network access |
The ability of a device to connect to other resources on a particular network. |
| network adapter |
A device that connects another device to a network. |
| networking gear |
Equipment used to connect computers (or other networkable equipment) to each other. |
| networking medium |
The networking technology used in a particular network. Common mediums are 10/100BASE-T for wired networks and Wi-Fi for wireless networks. |
| Neutral-density filter |
(ND) Mounted at front of camcorder lens, reduces light intensity without affecting its color qualities. [See filter.] |
| NiCad |
(nickel cadmium) Abbreviation coined and popularized by SAFT America for lightweight camcorder battery type designed to maintain power longer than traditional lead-acid batteries. |
| Nickel Metal Hydride Battery |
Composed of nickel hydroxide and a multicomponent, engineered hydride alloy consisting of vanadium, titanium, zirconium, nickel, and minor quantities of other metals. It is non-toxic and completely recyclable. |
| Nickel-Cadmium Battery |
Uses potassium hydroxide as the electrolyte with a nickel and cadmium electrode. Often held in a polypropylene container, these batteries are also often used in automobiles. |
| NiMH |
(nickel metal hydride) Battery technology similar to NiCad, but more environmentally friendly, with higher capacity and fewer memory recharging problems. |
| NLE |
(nonlinear editor/editing) Hard drive-based editing system defined by its ability to randomly access and insert video in any order at any time. This is in contrast to linear, tape-to-tape editing which requires rewinding and fast forwarding to access material. |
| node |
A device on a network that has its own unique IP address. |
| Noise |
Undesirable video or audio signal interference; typically seen as snow, heard as hiss. |
| Non-Drop Frame |
A type of SMPTE time code that continuously counts a full 30 frames per second. As a result, non-drop-fame time code does not exactly match real time. See also DROP FRAME. |
| Noninterlaced video |
Process of scanning complete frames in one pass, painting every line on the screen, yielding higher picture quality than that of interlaced video. Most computers produce a noninterlaced video signal; NTSC is interlaced. [See interlaced.] |
| Nonlinear editing |
Digital "cut and paste" editing that uses a hard drive instead of tape to store images. Random access allows easy arrangement of scenes in any order. Also eliminates the need for rewinding and allows for multiple dubs without generational loss. |
| Nonsynchronous sound |
Audio without precisely matching visuals. Usually recorded separately, includes wild sound, sound effects, or music incorporated in post-production. [See synchronous sound</I>.] |
| nose room |
The distance between the subject and the edge of the frame in the direction the subject is looking. Also called ?look room.? |
| NTSC |
(National Television Standards Committee) Group formed by Federal Communications Commission to regulate U.S. television broadcasting specifications. NTSC refers to all video systems conforming to this 525-line 30-frame-per-second signal standard. [See PAL, SECAM.] |
