| Lavaliere |
Small, easily concealed, unobtrusive, and aesthetically pleasing microphone, typically attached to clothing or worn around the neck for interview settings. |
| Layback |
Transferring the sweetened audio track back to the master video tape. See SWEETENING. |
| LCD |
(Liquid Crystal Display) Commonly used in digital watches, camcorder viewscreens and laptop computer screens, LCD panels are light-weight and low-power display devices. |
| Lead-Acid Battery |
Consists of several cells put in a series in a polypropylene container and uses lead oxide and spongy lead electrodes with sulfuric acid as an electrolyte. These are normally found in automobiles. |
| Lead-in |
The area of a Compact Disc between 23mm - 25mm containing the Table of Contents (TOC) data. |
| Leadout |
The area of a Compact Disc that follows the program area. |
| LiIon |
(Lithium Ion) The most common battery type among new camcorders. More expensive, but has a higher capacity and fewer memory rechanging problems. |
| Linear editing |
Analog, tape-based editing. Called linear because scenes are laid in a line along the tape. Has many disadvantages, such as the need to rewind and fast forward and the inability to insert footage without re-recording everything that follows. Compare with nonlinear editing. |
| Lip sync |
Proper synchronization of video with audio -- lip movement with audible speech. Better known as technique widely practiced with music video recordings, whereby "vocalists" mime to playback of prerecorded music. [See synchronous sound.] |
| Lithium Polymer Battery |
Uses lithium for an electrochemically active material, and the electrolyte is a polymer or polymer-like material that conducts lithium ions. |
| Lithium-Ion Battery |
Uses an electrochemically active material and an electrolyte liquid which conducts lithium ions. |
| Location |
Any place filming occurs except a studio. |
| Log |
A paper listing of the time code addresses of shots, scenes and takes. The log is an efficient way to find shots during editing. |
| Long shot |

| LP |
(long play) Middle tape speed of a VHS VCR, accommodating four-hour recordings. [See EP, SP.] |
| LTC |
(longitudinal time code) Frame identification numbers encoded as an audio signal and recorded lengthwise on the edge of a tape. (See time code, VITC). |
| Luminance |
Black-and-white portion of video signal, carries brightness information representing picture contrast, light and dark qualities; frequently abbreviated as "Y." [See chrominance.] |
| Lux |
Amount of lumens in a square meter. Means of measuring a camcorder's low-light sensitivity -- minimum amount of illumination required to record an "acceptable" image. Lower the lux reading the greater the sensitivity. |
