MTT Exam Competency 004
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.

Digital
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
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

Analog Digital
Non-Linear and Linear Editing
Non-linear editing on digital video
Non destructive processEasier to use, new
Linear editing on video tape
Destructive processOlder 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.

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
Photo compressed at 20%size37kb 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.

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).
2-Dimensional 3-Dimensional

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
