Glossary

Term	Definition
Audio Stems	In audio production, a stem is a discrete audio source to be used as one unit. At the Church, individual stems are used for music, effects, and dialogue (including language audio dialogue).
Binary or Blob	The actual asset (video, audio, image, document) vs the metadata record.
Black Pearl	This is the off-line tape storage system that is replacing DIVA.
Captioning	The addition of text to accompany an audio track, usually provided as a viewable option. It is department policy to provide captioning on all English videos that are posted online on any site owned or operated by the Church. It is also strongly encouraged (but not required) that captioning be included on all other languages. This was done to comply with recent interpretations of the Americans with Disabilities Act.
Cards (Camera card, Audio card, SD card)	A physical card used to store data, such as from a camera or audio device. In video production, camera cards and audio cards break together, so the card numbers consistently match at all points in production.
Clip	A short excerpt taken from a moving image or audio resource. A clip may not convey a complete intellectual concept.
Codec	A device or program that compresses data to enable faster transmission and decompresses received data. In this case, the term codec is an acronym for coder/decoder.
Color space	Color space is a mathematical model which describes a specific organization of colors, usually as a number or combination of letters or numbers. This allows for reproducible representations of color.
Exif	Exchangeable Image File (Exif) metadata embedded within all images captured with a digital camera. This information is automatically copied from the camera data or data the photographer or cinematographer added while editing the images or video.
Frame rates	The frequency at which frames in a video are displayed, usually expressed as frames per second (fps). The higher the frame rate, the smoother fast actions appear.
International Master	For a video, a master that is free of any text or titles and prepared so it can easily be adapted into a new language master. Basically, it is a Titled Master with final color correction work and final audio mix but without any text or titles. See the Video Production Standards for specifications on codecs, color space, and file formats.
IPTC	International Press Telecommunications Council (IPTC) metadata copied from the camera data or data the photographer or cinematographer added while editing the images or video.
Master Files	The files used to create a final product deliverable.
Metadata	Metadata is information about other data. For our purposes, it is descriptive, administrative, and reference information about an asset (video, image, audio, document).
Proxy	For a video, footage that is lower in resolution, with a smaller file size, and thus a lesser data rate, used for editing. The proxies in Nuxeo will be 720x480p, 800k, HLS format with timecode.
Renditions	Other formats for an asset. For published video: 1080,720,360 mp4. For published audio: 64kb mp4 for spoken audio only, 128kb for full fidelity content (e.g., music).
Resolution	Resolution refers to the number of pixels in an image. Resolution is sometimes identified by the width and height of the image as well as the total number of pixels in the image. For example, an image that is 2048 pixels wide and 1536 pixels high (2048 x 1536) contains (multiply) 3,145,728 pixels (or 3.1 Megapixels). The higher the resolution the more detail the image has.
Slate	A board with information written on it used to mark the beginning or end of a take. Since scenes are shot out of sequence and audio recorded separately from the visual portions of a production, the metadata written on the slate is crucial for identifying assets. When the shooting is completed, scenes, audio, and visual components are pieced together during editing with help from the video slate.
Stock Footage	Pre-recorded footage used or collected and organized to be used in the production of films, broadcasts, and video recordings.
Stock Image	Pre-captured image used or collected and organized to be used in the production of another product.
Timecode	Timecode, also known as SMPTE or SMPTE code, is an electronic signal which is used to identify a precise location in time-based media like audio or video. SMPTE is an acronym for Society of Motion Picture and Television Engineers, the developers of this standard.
Titled Master	For a video, a master that includes the final color correction work, titles, and the final audio mix. See the Video Production Standards for specifications on codecs, color space, and file formats.
Transcode	Transcoding is the process of converting video or audio from one editing or encoding format into another.
Vantage	A vendor used to transform and compress video footage and renditions.
