Master Technology Teacher Competency 004 Fabian SalcedoEDTC 6343
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.
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). • 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. • 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.
The Master Technology Teacher: • Knows how to use techniques for capturing and editing audio components during the video production process. • 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). • Knows how to convert between analog video and digital video.
Analog and Digital • Linear and nonlinear video editing. • Image ratio • Zoom/Focus and pan • Compression (Image, Video, and Audio) • 2 D and 3 D Effects Terminology
Video signal transferred by analog signal. • Contains the brightness & color of the image. • May be carried in separate channels • Component video • S-Video. • Or combined in one channel • Composite video • RF connector. Analog Video
Non-Digital (Analog) • Non-digital (or analog) use a continuous range of values to represent information. • http://en.wikipedia.org/wiki/Non-linear_editing_system
Analog Video • Two common video graphic aspect ratios are: • 4:3 Is the universal standard definition formats. • 16: 9 Is the universal to high definition formats.
A digital system uses discrete (discontinuous) values, usually but not always symbolized numerically (hence called "digital") to represent information for input, processing, transmission, storage, etc. Digital Video • http://en.wikipedia.org/wiki/Digital
Non-linear Video • Non-linear video editing is the process of selecting, arranging images and sound recorded on videotape but the original files are not lost of modified during editing. =
Linear Editing • Linear video editing is the process of selecting, arranging and modifying the images and sound recorded on videotape.
Zoom • Digital zoom decreasing the angle of view of a digital photographic or video image. • Digital zoom is also cropping an image down to a centered area with the same aspect ratio as the original. • http://en.wikipedia.org/wiki/Digital_zoom
Focus • Focus is the adjustment for distinct vision ; also: the area that may be seen distinctly or resolved into a clear image.
2 Dimensional Effect • 2 Dimensional Refers to objects that are constructed on two planes (X and Y, height and width, row and column, etc.). (Flat Objects)
3 Dimensional Effect • 3 Dimensional objects are constructed on three planes (X, Y and Z) (Items can be rotated into different views).
