level. Video: Brightness and contrast of the color. Audio: See gain.

LFOA. Last Frame of Action. Last frame of picture or sound on a film reel which is the final frame to be included when measuring reel length. The LFOA is noted on mix sheets and in the notes for each reel sent to the negative cutter. Same as LFOP.

LFOP. Last Frame of Picture. See LFOA.

lightstruck leader. Leader made from raw stock that the film lab has deliberately exposed to light so it becomes lightstruck and turns white.

Lightworks. Professional digital editing system.

limiter. An analog circuit in an audio recorder that automatically adjusts volume to prevent clipping when a digital or analog signal surpasses a preset level.

line cut. Tape of the switches from one camera angle to the other that the multiple cam director called out as the show was shot.

linear editing. Making or recording each edit sequentially from the beginning of the show to the end of the show.

lined script. Pages of script shot each day and marked by script supervisor with vertical lines indicating where each take starts and ends.

locked cut. Final edited cut that should be considered unchangeable.

lo-con. Low contrast positive film stock made from OCN, dupe neg, or interneg that’s printed and timed brighter in the lab then telecined to make a video master.

logger. 1) Person who enters (logs) info about tape (description, take number, time code etc.) so editor and other post personnel can locate footage. 2) Person who marks transcripts so editor and other post personnel can locate footage.

LokBox. Essentially an electronic synchronizer, the LokBox locks (syncs) a video tape machine with a film synchronizer so that the negative cutter can cut the negative. Used on shows that have been edited digitally and have no work print, the LokBox runs forwards and backwards and has also been used to cut sound on film.

lossy. Scheme of data compression which reduces the amount of data in the image so that when it’s decompressed some of the original data is lost. Commonly used for video and sound image files such as JPEGs and MPEGs where users won’t notice the image loss.

loupe. A small, single lens magnifying glass resembling a monocle used to examine film frames.

LTC. Longitudinal Time Code. Analog time code that can be read when the tape is moving and that is laid down lengthwise (longitudinally) during or after production to an audio track.

LTO. Linear Tape-Open. Magnetic tape storage technology used for archiving since it can hold hundreds of GB on a single cartridge.

luma. See luminance.

luminance. Non-color portion of a video image or signal that holds the black and white data (brightness and contrast).
