Competency 004: A

Demonstrates knowledge of basic concepts relating to video technology (e.g.

analog, digital) and understands differences and similarities between linear

and nonlinear editing.

Digital vs Analog

• Think….

• Uses an electrical signal to capture images on magnetic tape.• VHS, 8mm, Betamax

Digital• Almost all modern

technology uses digital image capturing.

• Uses a pattern of 0s & 1s to record images • DVDs, Digital8, DVCam

Analog

Digital vs Analog

• High resolution• Does not degrade when copied• Edited with computer• Nonlinear editing• Records with pattern of

numbers• DVD players, computers

• Records video

• Lower resolution• Degrades when copied• Edited with VCR set-up• Linear Editing• Records electronically on

magnetic tape• Who has a VCR still?

Nonlinear vs Linear EditingNonlinear Editing-

Digital• Computer Editing

• Source device, computer (200 MHz processor, 64 MB Ram, 1 GB of freespace), capture device*, leads, software, monitor

• Simple to set up, but harder to understand how to use*

Linear Editing- Analog

• “Tape to Tape”

• 2 VCRs, 1-2 monitors, cables, tapes

• Simple

• Allows users to edit and insert audio

• Uses fast forward & rewind• Analog recording• VHS• Simple Set-Up• 2 VCRs, 1-2 monitors, cables, tapes• Original lost after editing

• Add and Remove Sound, Images, and Text

• Can “skip” to scene• Digital recording• DVDs/CDs• Computer, video recorder, software• Original not lost after

editing

Linear Vs Nonlinear

But don’t take my word for it…

Studio 1 Shows you the Difference!

Competency 004: B

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).

Video Filming

• Webcam• Video Cameras• Flip cameras• Cell Phones
