Analog Camera – A camera that takes non-digital video. The term “analog” in video refers to a recording method that stores red, green and blue waves in a fixed number of rows; analog video is generally less crisp in detail than digital video.

Bandwidth – The amount of information that can be sent through a connection. Usually measured in bits-per-second. A fast modem can move about 57,000 bits in one second. Full-motion full-screen video would require roughly 10,000,000 bits-per-second, depending on compression.

Buffering Video – A buffer is a temporary holding pen in a computer’s memory for data for inputs (e.g., to software) or outputs (e.g., to a printer) until the process can deal with it. Video buffering occurs when a streaming video player saves portions of a streaming video file to local storage for playback.
Captions – Text that appears over a video that labels a scene, identifies a location or person, or narrates dialogue onscreen. Captions can be either open or closed.

Embed – Adding an element from one document to another document; in online video this refers to taking video from a online video provider and transplanting it elsewhere on the web (websites, social networking sites, etc.) through the use of HTML code.
Green screen – A screen placed in a video studio images can be projected onto. Television meteorologists frequently present the weather in front of a green screen or blue screen, and producers place maps over the blue portions of video footage, creating the appearance of the meteorologist standing in front of a large map. If the person standing in front of the screen wears the same color clothing as the screen, the projected images will appear on the person’s clothing.
HTTP Streaming – The default protocol for streaming audio and video over the internet. It involves the simultaneous download and viewing/listening of the file through HTTP. See also Progressive download.

IPTV – Internet Protocol Television- television content that is received by the viewer through the technologies used for computer networks. It is different from Internet TV in that Internet TV service providers cannot control the final delivery and IPTV service providers can. This allows more content to be available for Internet TV but at a lower quality and less content for IPTV but at a much greater quality. IPTV is often associated with VoD (video on demand).

Multi-title (video) Player – A video player that can play and display multiple videos, see playlist.
Non-Linear Editing – An editing method that allows the editor to access any frame in a video clip with the same ease as any other. This is opposed to linear editing in which analogue video is physically cut and pasted. Non-Linear editing is with digital video and is therefore non destructive to the original video.
Page View – a request to load a single page of an Internet site. On the World Wide Web a page request would result from a web surfer clicking on a link on another HTML page pointing to the page in question. This should be contrasted with a hit, which refers to a request for a file from a web server. There may therefore be many hits per page view. Page Views are also called Page Impressions.
Playlist – A sequence defining the order in which a collection of video or audio files will be played. For video, a playlist is displayed in a Mulit-title (video) Player.
Professional Video Hosting – These websites provide online video hosting and sharing for viewing by private and public audiences, similar to consumer video hosting, but at a cost. Accordingly, the video content is of higher quality and the users are given greater control of their videos.

Rule of Thirds – This rule involves envisioning a tic-tac-toe board on top of a video shot, so the image is divided into nine squares. The videographer should choose one of the four points of line intersection as a focal point. According to Digital Photography School, “The theory is that if you place points of interest in the intersections or along the lines that your photo becomes more balanced and will enable a viewer of the image to interact with it more naturally.”
Streaming Media – Internet video and/or audio clips that can play directly over the Internet, without needing to be downloaded first onto a computer. Used to view and hear broadcasts, and to interactively play and seek in stored clips. See also Pure Streaming.
Switcher – a device that allows a video producer to switch between multiple cameras to create a more visually interesting video and reduce editing time if the video is not live. Switching is used in most live television broadcasts.
