Digital Video/Audio
Sound Wave
Is an audible vibration that travels through air or water.
Trough
Is the point that exhibits maximum amount of downward displacement from the rest position.
Sample Size
Is the number of bits used to save one sample.
Digital Video
Are videos that are made up of 1’s and 0’s, binary format, that represent the video image which computers can read.
Preproduction
Are the tasks undertaken before production begins.
Frequency
Is the number of waves to pass a point in one second.
Pitch
Is the quality of the sound determined by the rate of vibration.
Mono
Is one channel; audio is a single channel, where sound comes from a single direction.
Capture
Is to record audio, video, or still images as digital data in a file.
Production
Is filming the video.
Ampltude
Is the distance from rest to crest or rest to trough.
Sampling
Is the process used to convert analog sound waves into digital data to be used by computers.
Stereo
Is two channels; creates the impression of sound being heard from various directions, as in human hearing.
Frame
Is a single picture or still shot in a video.
Postproduction
Is capturing the video and editing.
Wavelength
Is the distance from crest to crest.
Sample Rate
Is the number of samples taken per second, often measured in Kilohertz (kHz).
Audio File Size
Is determined by the sample rate, sample size and number of channels used.
Resolution
Is the number of pixels that can be displayed on a screen.
Sound Effects
Is artificially created or enhanced sounds to emphasize content or enhance a creative point in a video.
Crest
Is the point that exhibits maximum amount of upward displacement from the rest position.
Bit Rate (Depth)
Is the number of computer bits process per unit of time.
Is video uses a continuous electrical signal to capture footage on a magnetic tape.
Frame Rate
Is the number of video frames played per second.
Video Effects
Enable you to add special effects to your movie, such as a vintage look or changing a video to black and white.
