Edit Decision List
An edit decision list (EDL) is a structured document that records every edit in a sequence — including source reels, timecodes, transition types, and durations — enabling a final cut to be precisely recreated from original source material..
Emotion Detection
Emotion detection in video is an AI analysis technique that interprets facial expressions, body language, vocal tone, and contextual cues to infer the emotional states of people appearing on screen..
Footage Logging
Footage logging is the process of systematically reviewing, annotating, and documenting raw video content with descriptions, timecodes, ratings, and keywords to make clips findable and useful during editing..
Frame Rate
Frame rate is the frequency at which consecutive still images (frames) are captured or displayed per second in video, measured in frames per second (fps), directly affecting motion smoothness and temporal resolution..
HDR Workflow
An HDR workflow encompasses the end-to-end process of capturing, editing, grading, and delivering high dynamic range video that preserves greater detail in highlights and shadows than standard dynamic range content..
Look-Up Table
A look-up table (LUT) is a mathematical formula that maps input color values to transformed output values, used to convert between color spaces, apply creative color grades, or preview a final look on set..
Lower Third
A lower third is a graphic overlay positioned in the bottom portion of the video frame, typically used to identify speakers, display titles, show locations, or present supplementary text information..
Media Asset Management
Media asset management (MAM) is an enterprise-grade system for ingesting, cataloging, storing, searching, distributing, and archiving large-scale media libraries including video, audio, images, and associated metadata across production workflows..
Media Ingest
Media ingest is the systematic process of importing raw footage and associated files from cameras, storage cards, and external sources into a production system, including verification, organization, backup, and preparation for editing..
Metadata Schema
A metadata schema is a structured framework that defines what descriptive, technical, and administrative information is recorded about media assets — including field names, data types, controlled vocabularies, and relationships — to ensure consistent and searchable organization..
Motion Graphics
Motion graphics are animated visual elements — including text, shapes, icons, data visualizations, and transitions — designed to communicate information or enhance video content through movement and design..
Multimodal Embeddings
Multimodal embeddings are AI-generated mathematical representations that capture meaning across multiple types of content simultaneously — including visual frames, spoken audio, on-screen text, and music — within a unified vector space..
Non-Linear Editing
Non-linear editing (NLE) is a digital video editing method that allows instant random access to any frame in the source material, enabling editors to assemble, rearrange, and modify sequences in any order without destructive changes to original files..
Proxy Editing
Proxy editing is a workflow technique where editors work with lower-resolution copies of original footage to improve playback performance and editing speed, then relink to full-resolution files for final output..
Render Farm
A render farm is a networked cluster of computers that distributes computationally intensive video rendering, VFX processing, and export tasks across multiple machines to dramatically reduce processing time..
Review and Approval
Review and approval is the structured workflow for collecting stakeholder feedback, managing revision requests, and obtaining formal sign-off on video content before final delivery or publication..
