Competency 004 The Master Technology Teacher knows and applies basic strategies and techniques for using digital video technology.

The Master Technology Teacher: Demonstrates knowledge of basic concepts relating to video technology (e.g., analog, digital) and understands differences and similarities between linear and nonlinear editing.

Analog Analog: An electrical signal that continuously varies in strength as related to some form of input. Analog Recording: A means of recording audio or video whereby the recorded signal is a physical representation of the waveform of the original signal. http://www.filmland.com/glossary/Dictionary.html http://www.yourdictionary.com/images/computer/ CARRIER.GIF

Digital Digital: A reference to a system whereby a continuously variable analog signal is reduced and encoded into discrete binary bits that establish a mathematical model of an original signal or other information. http://www.filmland.com/glossary/Dictionary.html Digital Recording: A method of recording in which samples of the original analog signal are encoded on tape or disk as binary information for storage or processing. The signal can then be copied repeatedly with no degradation. http://www.filmland.com/glossary/Dictionary.html

Non-Linear and Linear Editing Non-linear editing on digital video Non destructive process Easier to use, new Linear editing on video tape Destructive process Older method of cut and paste.

The Master Technology Teacher: Demonstrates knowledge of basic concepts of video filming(e.g., composition, ratio of image to frame, position in frame, line of gaze, pans/tilts, movement, perspective). Composition- arrangement of elements in a frame Aspect ratio- width by height ex. 4:3, 16:9 Pans- right to left or left to right movement Tilts- up and down movement Perspective- camera view

The Master Technology Teacher: Knows a variety of basic video techniques(e.g., zoom, focus, filters) and lighting techniques(e.g., key fill, backlight)and how to use incident/reflected light, color, temperatures and filters.

Video Techniques-Zoom (In- Out)

Video Technique Focus

Lighting Techniques Key light Back Light Fill Light http://matbury.com/wordpress/wp-content/uploads/2009/07/three-point.jpg

The Master Technology Teacher: Demonstrates knowledge of compression schemes for a variety of file types (e.g., photographs, animation, audio, video, graphics) and knows compression strategies, programs, and techniques to conserve memory and retain image integrity when digitally capturing files.

Compression Schemes Lossy compression means compressed file has less data than original file. Lossless compression means none of the information is lost.

Compression Photographs- are compressed into jpeg files Animation - into Gif files Sound- Mp3 files Video graphics MPEG-1 MPEG-2 MPEG-4

Photograph Compression http://computer.howstuffworks.com/question289.htm Photo compressed at 20%size37kb http://computer.howstuffworks.com/question289.htm Photo compressed at 95% size4kb

The Master Technology Teacher: Knows how to use techniques for capturing and editing audio components during the video production process. Microphone Music Narration

The Master Technology Teacher: Demonstrates knowledge of techniques used in postproduction(e.g./ editing and creating control and /or time coded tracks; creating transitions, captions and titles; applying 2 –D and 3-D animation effects).

Animation Effects 2-Dimensional 3-Dimensional http://www.squidoo.com/3d-animation-studio

The Master Technology Teacher: Knows how to convert between analog video and digital video. http://www.homesecuritystore.com/p-214-ad02a-usb-20-analog-to-digitalvideo-converter.aspx ?affiliateid 10054&zmam 55691497&zmas 1&zmac 4&zmap AD02A

Vocabulary Non-Linear Editing Linear Video Editing Analog Recording Digital Digital Recording Composition Pan Tilt Zoom Filter Backlight Key Light Fill Light Aspect Ratio 2D animation 3D animation Lossy Compression MPEG-1 MPEG-2 MPEG-4 Omnidirectional Unidirectional Shotgun Lavalier

Non-Linear Editing Modern editing method which involves being able to access any frame in a digital video clip with the same ease as any other

Linear Video Editing Process of selecting, arranging and modifying the images and sound recorded on videotape. Cutting of the negatives made it a destructive process

Analog Recording A means of recording audio or video whereby the recorded signal is a physical representation of the waveform of the original signal

Digital A reference to a system whereby a continuously variable analog signal is reduced and encoded into discrete binary bits that establish a mathematical model of an original signal or other information

Digital Recording A method of recording in which samples of the original analog signal are encoded on tape or disk as a binary information for storage or processing. The signal can then be copied repeatedly with no degradation.

Composition Visual make-up of a video picture, including such variables as balance, framing, field of view and texture all aesthetic considerations. Combined qualities form an image that’s pleasing to view.

Pan Horizontal camera pivot, right to left or left to right, from a stationary position

Tilt Vertical camcorder rotation(up and down) from a single axis, as on a tripod

Zoom An optical effect in which the image rapidly grows larger or smaller as though the camera is moving closer or away from its subject

Filter Any device placed on a lens or light source that alters the quality of the passing light

Backlight A light which is generally mounted behind a subject to light the subject’s hair and shoulders without illuminating a subject’s front.

Key Light The main light on a subject

Fill Light May be used to reduce the contrast of a scene and provide some illumination for the areas of the image that are in shadow

Aspect Ratio The proportion of picture width to height

2D Animation Everything happens on a 2 dimensional platform. Pictures are flat, without depth and offer only one perspective

3D animation Everything happens on a 3 dimensional platform. Pictures have depth and offer multiple perspectives just like in real life and have soft subtle shadows casted on the objects and characters within.

Lossy Compression Compressed file has less data in it than the original file

MPEG-1 Standard for the compression of moving pictures and audio

MPEG-2 Standard on which digital television set top boxes and dvd compression is based

MPEG-4 Standard for multimedia and web compression

Omnidirectional An omnidirectional (or nondirectional) microphone's response is generally considered to be a perfect sphere in three dimensions

Unidirectional A unidirectional microphone is sensitive to sounds from only one direction

Shotgun “Shotgun” microphones are the most highly directional

Lavalier A lavalier microphone is made for hands-free operation
