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. 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 Vs. Analog

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

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%size37kbPhoto 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

The Master Technology Teacher: Knows how to convert between analog video and digital video. video-converter.aspx ?affiliateid=10054&zmam= &zmas=1&zmac=4&zmap=AD02A
