Notice of Deposition

A legal document that states when, where, and before whom a deposition will take place; the videographer uses it to confirm scheduling, participants, and any special recording instructions.

Related: Site Survey, Pre-Flight Check
Site Survey

A visit to or assessment of the recording location before the proceeding to check space, power, lighting, acoustics, and seating so camera and microphone placement can be planned.

Related: Camera Placement, Notice of Deposition
Pre-Flight Check

A systematic test of camera, audio, lighting, media, and power before recording starts, confirming that every component works and that settings match the plan.

Related: Test Recording, Backup Recording
Camera Placement

The planned position and height of the camera relative to the witness, bench, and exhibits, chosen to give a clear view without blocking participants or sightlines.

Related: Site Survey, Framing
Test Recording

A short trial recording made before the proceeding and reviewed for image, sound, timecode, and media performance so problems are found before testimony begins.

Related: Pre-Flight Check, Timecode
Backup Recording

Recording simultaneously to a second media or device so that a failure in one recorder does not destroy the only copy of the testimony.

Related: Pre-Flight Check, Chain of Custody
Timecode

A frame-based time reference embedded in the recording that lets anyone locate a precise moment and synchronize video with audio, transcripts, or other recordings.

Related: Synchronization, Frame Rate
Frame Rate

The number of video frames captured each second; it must be set consistently to produce smooth motion and remain compatible with playback and editing systems.

Related: Timecode, Deliverable Format
Exposure

The overall amount of light reaching the camera sensor, controlled by iris, gain, and shutter settings; correct exposure keeps faces and documents clearly visible.

Related: Iris, Gain
Iris

An adjustable opening in the lens that controls how much light enters the camera; changing it affects both image brightness and depth of field.

Related: Exposure, Depth of Field
Gain

Electronic amplification of the camera signal used when light is low; raising gain brightens the picture but also increases visual noise.

Related: Exposure, Iris
Depth of Field

The range of distance in front of the camera that appears in focus; a shallow range isolates the speaker while a deep range keeps documents and room details sharp.

Related: Iris, Framing
Framing

The composition and crop of the picture, such as a medium shot of the witness, selected to show the face, hands, and relevant surroundings clearly.

Related: Camera Placement, Depth of Field
Locked-Down Shot

A camera fixed securely on a tripod and left stationary so the image stays stable and does not distract viewers from the testimony.

Related: Camera Placement, Framing
Color Temperature

A measure in kelvin of how warm or cool a light source appears; matching the camera to the room's light keeps skin tones and exhibit colors natural.

Related: White Balance, Glare
White Balance

A camera adjustment that makes white objects look neutral under the room's lighting, preventing unwanted blue or orange color casts in the recording.

Related: Color Temperature, Glare
Lavalier Microphone

A small clip-on microphone attached to a speaker's clothing that picks up the voice consistently while rejecting much of the surrounding room noise.

Related: Wireless Microphone, Audio Levels
Boundary Microphone

A flat microphone placed on a table surface that captures voices from several people seated around it, making it useful for deposition tables.

Related: Audio Levels, Monitoring
Wireless Microphone

A microphone that sends audio by radio to a receiver; it requires frequency coordination, fresh batteries, and monitoring to prevent dropouts or interference.

Related: Lavalier Microphone, Monitoring
Audio Levels

The strength of the recorded sound as shown on meters; levels are kept in a steady range to avoid distortion when loud and inaudibility when soft.

Related: Monitoring, Automatic Gain Control
Automatic Gain Control

A camera feature that constantly adjusts audio volume; it is normally switched off for legal recording because it boosts background noise during quiet moments.

Related: Audio Levels, Monitoring
Monitoring

Listening to the audio through headphones while recording so dropouts, hum, clipping, or other problems can be detected and corrected immediately.

Related: Audio Levels, Wireless Microphone
Three-Point Lighting

A standard setup using a key light, a fill light, and a back light to illuminate the subject evenly and separate them from the background.

Related: Color Temperature, Glare
Glare

Unwanted reflection from windows, eyeglasses, or glossy exhibits that washes out detail; it is controlled by changing light angles or camera position.

Related: Three-Point Lighting, White Balance
Chain of Custody

A documented record of who handled the recordings and media at every stage, from capture through editing, delivery, and storage, proving they were not altered.

Related: Retention, Checksum
Recording Log

A written record of start and stop times, media used, participants, and notable events during a proceeding, used later to locate specific segments.

Related: Timecode, Synchronization
Synchronization

Aligning video with a transcript or separate audio track so that any spoken word can be found at the correct point in the recording.

Related: Timecode, Recording Log
Redaction

Removing or obscuring confidential information, such as names, faces, or documents, from a recording before it is released to others.

Related: Deliverable Format, Confidentiality
Checksum

A digital fingerprint calculated from a file; recalculating it later and comparing the values verifies that the recording has not been altered.

Related: Chain of Custody, Retention
Deliverable Format

The file type and physical or digital medium specified for the final product, chosen so courts and parties can play it reliably.

Related: Frame Rate, Redaction
Impartiality

Remaining neutral and unbiased, recording all testimony accurately and completely without favoring any party, coaching a witness, or influencing what is said.

Related: Code of Ethics, Conflict of Interest
Confidentiality

Keeping recordings and details about the proceeding private and sharing them only with persons authorized by law or the parties.

Related: Redaction, Code of Ethics
Conflict of Interest

A personal, financial, or professional relationship that could bias the videographer's work or judgment; it must be disclosed to the parties and avoided.

Related: Impartiality, Code of Ethics
Off the Record

A pause when the proceeding is not being recorded; the videographer should confirm the instruction and note the pause in the log.

Related: Recording Log, Impartiality
Retention

The policy and legal requirements for how long raw and final recordings are kept and how they are stored securely.

Related: Chain of Custody, Checksum
Code of Ethics

Professional standards that require honesty, neutrality, competence, and respect for the legal process, guiding how a legal videographer behaves and makes decisions.
